NFL Weather Betting Guide: How Weather Affects Spreads, Props and Totals
Weather is one of the most overlooked edges in NFL betting. While casual bettors focus on team stats and injury reports, sharp bettors check the forecast before placing any outdoor game bet. Wind, rain, cold, and snow can swing NFL spreads by 3-7 points, slash quarterback passing yards by 50+, and turn high-scoring affairs into defensive slugfests.
Why do most bettors ignore weather? They assume sportsbooks have already priced it in, or they dismiss light conditions as irrelevant. Both assumptions are wrong. Sportsbooks set opening lines assuming normal conditions, then react as forecasts develop. Bettors who anticipate weather-driven line moves consistently find value before the market adjusts. Historical data shows that totals unders in games with 20+ mph wind hit at rates exceeding 55%, a meaningful edge over the long term.
This guide covers how weather affects every NFL bet type: spreads, moneylines, player props, game props, and totals. Unlike generic weather advice, you will learn the exact thresholds that matter, specific adjustments for each bet type, and a systematic process for incorporating weather into your handicapping. Whether you are betting Sunday morning or looking for live value as conditions change, this guide gives you the framework sharp bettors use.

Why Weather Matters in NFL Betting
NFL games are played outdoors in 21 of 32 stadiums. From September through January, teams face everything from 90-degree heat in early season games to blizzard conditions in playoff matchups. Weather directly impacts player performance, game strategy, and final scores.
Most recreational bettors either ignore weather entirely or overreact to light conditions that do not significantly affect outcomes. The betting edge comes from understanding exactly when weather matters and how to adjust your bets accordingly.
The weather betting advantage:
- Sportsbooks set lines assuming normal conditions, then adjust as weather forecasts become clearer
- Early bettors who anticipate weather-related line moves get better numbers
- Weather affects certain bet types more than others, creating targeted opportunities
- Team-specific tendencies in bad weather are often undervalued

NFL Stadium Weather Overview
Before diving into specific bet types, you need to know which stadiums have weather and which do not.
Dome Stadiums (No Weather Impact)
Eight NFL teams play in fully enclosed dome stadiums:
| Team | Stadium | Notes |
|---|---|---|
| Atlanta Falcons | Mercedes-Benz Stadium | Retractable roof, usually closed |
| Dallas Cowboys | AT&T Stadium | Retractable roof, usually closed |
| Detroit Lions | Ford Field | Fixed dome |
| Houston Texans | NRG Stadium | Retractable roof |
| Indianapolis Colts | Lucas Oil Stadium | Retractable roof |
| Las Vegas Raiders | Allegiant Stadium | Fixed dome |
| Minnesota Vikings | U.S. Bank Stadium | Fixed dome |
| New Orleans Saints | Caesars Superdome | Fixed dome |
Dome game adjustments: Expect 2-3 higher game totals in dome games compared to outdoor games in similar conditions. Pass-heavy offenses perform at their ceiling indoors.
Notorious Weather Stadiums
Some outdoor stadiums are famous for extreme weather:
Buffalo (Highmark Stadium): Lake effect snow, brutal wind off Lake Erie, sub-20 degree temperatures common in December and January.
Green Bay (Lambeau Field): The Frozen Tundra lives up to its name. Single-digit temperatures and snow are common in late-season games.
Chicago (Soldier Field): Wind off Lake Michigan is the primary factor. December and January games often feature 20+ mph gusts.
Cleveland (Cleveland Browns Stadium): Similar to Buffalo with lake effect conditions and strong winds.
New England (Gillette Stadium): Cold and windy, though less extreme than Buffalo or Green Bay.
Denver (Empower Field): Altitude affects kicking more than weather, but thin air and cold temperatures impact late-season games.
How Weather Affects NFL Spreads
Weather can swing NFL spreads by 3-7 points depending on severity. The key is understanding which teams benefit or suffer in adverse conditions.
Wind and NFL Spreads
Impact: Wind reduces passing efficiency, limits deep balls, and shortens field goal range. Teams with strong running games and good defenses gain an advantage.
Threshold: 15+ mph sustained winds start affecting spreads meaningfully. 20+ mph is a major factor.
Spread adjustments:
- Pass-heavy favorites in 15-20 mph wind: Reduce expected margin by 2-3 points
- Pass-heavy favorites in 20+ mph wind: Reduce expected margin by 4-6 points
- Run-heavy underdogs in high wind: Add 1-3 points of value
Example: The Chiefs (pass-heavy) are 7-point favorites at Buffalo in 25 mph wind. The spread should probably be closer to 3-4 points because Kansas City cannot rely on their vertical passing game.
Rain and NFL Spreads
Impact: Rain increases fumbles, reduces passing efficiency, and slows the pace of play. Teams with ball security issues and pass-dependent offenses struggle.
Threshold: Light rain (under 0.1 inch per hour) has minimal impact. Moderate to heavy rain (0.2+ inch per hour) affects spreads.
Spread adjustments:
- Pass-heavy teams in moderate rain: Reduce expected margin by 1-2 points
- Teams with fumble issues in heavy rain: Consider fading
Example: A pass-first team that averages 35+ pass attempts faces a run-heavy opponent in steady rain. The spread should tighten by 1-3 points.
Cold Weather and NFL Spreads
Impact: Extreme cold (below 20 degrees) numbs hands, hardens the ball, and affects passing accuracy. Warm-weather teams (Miami, Arizona, LA teams) struggle in extreme cold.
Threshold: Below 30 degrees starts mattering. Below 20 degrees is significant.
Spread adjustments:
- Warm-weather team at cold-weather site in sub-20 temps: Add 2-3 points to the home team
- Dome team playing outdoors in extreme cold: Add 1-2 points to the outdoor team
Example: Miami visits Buffalo in January. Temperature is 12 degrees. The Bills should get an extra 2-3 points beyond what the matchup suggests on paper.
Snow and NFL Spreads
Impact: Snow creates the most chaotic game conditions. Visibility drops, footing becomes unpredictable, and passing is severely limited.
Threshold: Accumulating snow has major impact. Light flurries matter less.
Spread adjustments:
- Any game with 2+ inches of accumulating snow: Spreads become less predictable
- Pass-heavy teams in snow: Expect significant regression
- Teams with experienced cold-weather QBs (Allen, Rodgers): Slight advantage
Example: Snow games often become coin flips. Heavy favorites in blizzard conditions frequently fail to cover.
How Weather Affects NFL Moneylines
Weather creates upset opportunities by leveling the playing field. When conditions limit what teams can do offensively, superior talent matters less. This is where moneyline underdogs find their best value.
The principle is simple: bad weather compresses the talent gap. A team that wins by 10 points in normal conditions might only win by 3 in a blizzard, or lose outright. Heavy favorites laying -300 or more become vulnerable when their offensive advantages are neutralized.
Historical Weather Upsets
Weather has produced some of the most memorable NFL upsets:
- 2023 Wild Card: Miami entered Kansas City as slight underdogs in -4°F temperatures. The Dolphins, a dome-trained warm-weather team, managed just 14 points as their passing attack froze. Cold-weather preparation matters.
- 2017 Week 14: Buffalo hosted Indianapolis in a lake-effect blizzard with 2+ feet of snow. The Bills won 13-7 in a game where neither team could move the ball consistently. Snow games become survival contests.
- 2007 Week 15: The Browns upset the Bills 8-0 in a wind-driven snow game where neither team scored a touchdown. Extreme weather makes any result possible.
When to Bet Underdogs in Bad Weather
Target these situations:
- Run-heavy underdog vs pass-heavy favorite in high wind: The underdog can execute their gameplan while the favorite cannot
- Cold-weather underdog hosting warm-weather favorite in extreme temps: Home team has experience advantage
- Any heavy underdog (+200 or more) in blizzard conditions: Chaos benefits the worse team
- Dome team traveling to notorious weather stadium late in season: Vikings, Falcons, and Saints historically struggle in December road games at Buffalo, Green Bay, or Chicago
Calculating weather-adjusted moneyline value: If you project a game as a toss-up due to weather but the moneyline shows +250 on the underdog, that represents significant expected value. A +250 underdog needs to win just 28.6% of the time to break even. If weather makes it a 40% proposition, you have a strong bet.
Example: A 10-point underdog with a strong running game faces a dome team in 22 mph wind and rain. The moneyline might offer +350 value because the favorite cannot play their style.
When to Avoid Favorites in Bad Weather
Fade favorites when:
- Favorite is a dome team playing outdoors in severe weather
- Favorite relies heavily on vertical passing (60%+ pass rate)
- Weather is extreme (25+ mph wind, heavy snow, sub-15 temps)
- Spread is 7+ points in bad weather (difficult to cover)
Dome team road struggles: Teams that play 8 home games indoors face a significant adjustment when traveling to outdoor stadiums in November through January. The Vikings, Falcons, Saints, Raiders, and Lions all show decreased road performance in cold-weather outdoor games. Track these matchups closely when weather is forecasted.
How Weather Affects NFL Player Props
Player props offer the most targeted weather betting opportunities. Specific positions and stat categories are dramatically affected by conditions.
Quarterback Passing Props in Weather
Wind impact on passing:
- 15-20 mph wind: Expect 10-15% reduction in passing yards
- 20+ mph wind: Expect 20-30% reduction in passing yards
- 25+ mph wind: Expect 30%+ reduction in passing yards
Passing prop strategy:
- Under on passing yards is the most profitable weather prop bet
- Target QBs with lines set at their normal averages when weather will limit production
- Deep ball QBs (Mahomes, Herbert) are affected more than short-game QBs
Rain impact on passing:
- Moderate rain: 5-10% reduction in passing yards
- Heavy rain: 15-20% reduction in passing yards
- Interception overs can have value (wet balls are harder to catch)
Example: Patrick Mahomes passing yards is set at 285.5. Weather shows 22 mph sustained wind. His under has significant value because Kansas City will run more and avoid deep shots.
Rushing Props in Weather
Weather generally helps rushing production:
- Teams run more in bad weather (fewer pass attempts)
- Running backs get more volume
- However, severe cold can make runners more cautious
Rushing prop strategy:
- Over on rushing yards for lead backs in bad weather games
- Over on rushing attempts has even more value
- Target teams that already run frequently (Ravens, 49ers, Browns)
Example: Derrick Henry rushing yards is set at 75.5. Heavy rain forecast. Tennessee will likely run 25+ times instead of their usual 18-20. His over has value.
Receiving Props in Weather
Wind impact on receiving:
- Deep threat receivers suffer most (fewer downfield targets)
- Slot receivers maintain more value (short routes less affected)
- Tight ends often see increased targets in wind games
Receiving prop strategy:
- Under on deep threat receivers in high wind
- Consider tight end overs (safer targets)
- Avoid receiving touchdown props (fewer red zone passes)
Example: A speedy deep threat has his receiving yards line at 65.5. Wind forecast shows 20 mph. His under has value because the QB will avoid deep shots.
Kicker Props in Weather
Wind impact on kicking:
- 15+ mph wind: Field goal range drops from 52+ to 45 yards
- 20+ mph wind: Field goal range drops to 40 yards
- 25+ mph wind: Even short field goals become risky
Kicker prop strategy:
- Under on field goal makes in high wind
- Under on kicker points in extreme weather
- Teams go for it on 4th down more often in wind (limits FG attempts)
Example: Kicker total points is set at 8.5 in a 25 mph wind game. Teams will likely go for touchdowns or punts instead of attempting field goals. Under has strong value.
How Weather Affects NFL Totals
Game totals are the most commonly bet weather market. For a deep dive on weather and totals, see our guide on how weather affects over/under betting.
Quick Reference Weather Thresholds for Totals
| Condition | Threshold | Total Adjustment |
|---|---|---|
| Wind | 15-20 mph | -2 to -4 points |
| Wind | 20+ mph | -4 to -6 points |
| Rain | Moderate | -1 to -3 points |
| Rain | Heavy | -3 to -5 points |
| Cold | Below 25F | -2 to -3 points |
| Snow | Accumulating | -4 to -8 points |
| Dome | Indoor | +2 to +3 points |
Example: Chiefs at Bills with an opening total of 52.5. Forecast shows 18 mph wind and light rain. Adjusted expectation: 46.5-48.5. The under likely has value.
For complete totals betting strategy, see our over/under betting guide and totals strategy guide.
NFL Weather Betting Strategy
Knowing how weather affects games is only half the equation. You also need to know when to bet and how to find value.
When to Bet NFL Weather Games
Bet early when:
- Weather forecast is already severe (72+ hours out)
- You expect the line to move toward under or toward the weather-favored team
- Example: Snow is forecast for Sunday in Buffalo. Bet the under Thursday before it moves.
Bet late when:
- Weather forecast is uncertain
- You want to see final conditions before committing
- Live betting during weather games can offer value
Timing matters: Sportsbooks adjust lines as weather forecasts become clearer. The biggest line moves happen 24-48 hours before kickoff when forecasts solidify.
How Sharps Approach Weather Betting
Sharp weather betting principles:
- Quantify the adjustment: Sharps assign specific point values to weather conditions, not vague leans
- Compare to market: If you think weather reduces the total by 4 points but the line only dropped 2, there is value
- Fade public overreaction: Sometimes the public overreacts to weather, creating value on the other side
- Look for props: Weather props (especially passing unders) are often slower to adjust than totals
Building Weather Into Your Handicapping
Weather handicapping process:
- Check weather forecast 72 hours before game
- Identify games with significant weather (15+ wind, moderate+ precip, sub-25 temps)
- Quantify expected impact on totals, spreads, and props
- Compare your projections to current lines
- Recheck forecast 24 hours before game
- Final check 2-3 hours before kickoff
- Adjust or pass if conditions change significantly
Weather Forecasting Resources for NFL Bettors
Accurate weather data is essential for weather betting. Here are the best sources.
Primary Weather Sources
Weather.com / Weather.gov:
- Most reliable forecasts
- Use hourly forecast for game time (not daily high/low)
- Check wind speed and direction specifically
NFLWeather.com:
- NFL-specific weather resource
- Shows game-time conditions for every outdoor game
- Historical weather trends by stadium
Twitter/X:
- Beat reporters often post weather updates
- Search team name + weather for real-time info
- Local TV meteorologists provide detailed forecasts
When to Check Weather
72 hours before: Initial check to identify potential weather games
24 hours before: Forecasts become more accurate, make preliminary bets
2-3 hours before kickoff: Final conditions, adjust if needed
During game: Conditions can change, affects live betting
Stadium-Specific Considerations
Lake effect stadiums (Buffalo, Cleveland): Weather can change rapidly. Check lake effect predictions specifically.
Coastal stadiums (Miami, Tampa, Jacksonville): Monitor for storms and wind off the ocean.
Mountain stadiums (Denver): Altitude affects kicking more than weather, but thin air changes ball flight.
Common NFL Weather Betting Mistakes
Avoid these errors that cost bettors money.
Mistake 1: Overreacting to Light Weather
The error: Betting unders because there is a 30% chance of light rain or 10 mph wind.
The fix: Only adjust for significant weather. Light conditions (under 15 mph wind, light rain, temps above 30) have minimal impact on NFL games.
Mistake 2: Ignoring Team Tendencies
The error: Assuming all teams are affected equally by weather.
The fix: Teams that already run heavy (Ravens, 49ers, Browns) are less affected by bad weather. Pass-heavy teams (Dolphins, Bengals) suffer more.
Mistake 3: Betting Too Early Without Weather Updates
The error: Betting Thursday for a Sunday game based on early forecasts, then weather changes.
The fix: Initial forecasts beyond 72 hours are unreliable. Wait for forecasts to solidify or be prepared to adjust.
Mistake 4: Forgetting Dome Team Adjustments
The error: Not accounting for dome teams playing outdoors in weather.
The fix: Teams that play 8 home games indoors (Vikings, Falcons, Saints, etc.) are less prepared for extreme outdoor conditions.
Mistake 5: Only Betting Totals
The error: Focusing exclusively on over/under bets in weather games.
The fix: Player props (especially passing unders) often offer better value because they adjust slower than totals.
Frequently Asked Questions
How much does wind affect NFL games?
Wind becomes significant at 15+ mph sustained speeds. At 15-20 mph, expect passing efficiency to drop 10-15% and game totals to be 2-4 points lower. At 20+ mph, the impact doubles. Wind primarily affects deep passing, field goal range, and punt distances.
Should I always bet the under in bad weather NFL games?
Not always. The value depends on whether the line has already adjusted for weather. If a total opens at 48 and drops to 43 because of weather forecasts, the under may no longer have value. Look for games where your weather adjustment exceeds the market adjustment.
Which NFL teams perform best in bad weather?
Teams with strong running games and defenses perform best in weather. Historically, Buffalo, Green Bay, and Baltimore have thrived in adverse conditions. These teams have offensive systems that do not rely heavily on the passing game and QBs comfortable in cold weather (Josh Allen, Aaron Rodgers).
Do warm-weather NFL teams really struggle in the cold?
Yes, there is measurable data supporting this. Dome teams and warm-weather teams (Miami, Arizona, LA teams) show decreased offensive efficiency in sub-30 degree games. The effect is most pronounced when temperatures drop below 20 degrees. Miami in particular has a poor historical record in extreme cold.
How do I check weather for NFL games?
Use Weather.com or Weather.gov for accurate forecasts. Check the hourly forecast for game time, not the daily summary. Pay attention to wind speed (not gusts), precipitation probability and intensity, and temperature. NFLWeather.com also provides NFL-specific forecasts for all outdoor games.
Does rain affect NFL passing more than cold?
Moderate to heavy rain typically affects passing more than moderate cold. Rain makes the ball slippery, increases fumbles, and disrupts timing. However, extreme cold (below 15 degrees) can be worse than rain because it affects ball grip and hand dexterity for both QBs and receivers.
When is the best time to bet NFL weather games?
If weather is already clearly severe in the forecast (72+ hours out), bet early before lines adjust. If weather is uncertain, wait until 24-48 hours before the game when forecasts solidify. For live betting, weather games can offer value when conditions change mid-game.
Are NFL player props affected by weather?
Yes, player props are significantly affected and often adjust slower than totals. Passing yards unders are the most profitable weather prop because QBs throw less often and attempt fewer deep balls. Rushing overs can also have value because teams run more in bad weather.
Summary
Weather betting is an underutilized edge in NFL betting. Most recreational bettors ignore weather entirely, and sportsbooks cannot perfectly price in every weather scenario.
Key takeaways:
- Wind over 15 mph significantly impacts passing, field goals, and game totals
- Rain and snow favor running teams and defensive games
- Extreme cold hurts warm-weather and dome teams
- Player props (especially passing unders) often offer the best weather value
- Check weather 72 hours, 24 hours, and 2-3 hours before kickoff
- Quantify adjustments rather than making vague leans
