TL;DR

  • Weather can affect player performance, scoring, and overall outcomes of games.
  • Always take the weather into account when doing your betting research.
  • Sportsbooks factor the conditions into the pricing of their lines and props.

The relationship between weather and sports betting is a vital one for smart gamblers. They understand the potential weather impact on games, whereas casual bettors often overlook this when making selections. It’s time for you to take into account how the weather affects different sports so that you can spot wagering opportunities.

Why weather matters in sports betting

It’s vital to understand how weather affects betting odds relating to certain sports. Outdoor events such as football, tennis, and baseball can be affected by rain, wind, cold, or heat, and that means there is a weather impact on those games.

Any bettor needs to understand the link between weather and sports betting all year round, not just in extreme conditions. Dedicated bettors factor climate variability into their selections, realizing it’s a key data point. All too many casual bettors overlook it. 

Online sportsbooks are constantly improving the way they adjust their lines in response to changes in weather, and they keep an eye on the forecast to anticipate how the weather may impact in-play betting on a game.  

How weather affects specific sports

🏈 American Football

When it comes to NFL betting and weather conditions, there are several ways in which the climate can make a big difference:

  • If it’s raining, passing and catching the ball becomes more difficult, so factor that into prop bets on rushing and passing yards.
  • Quarterbacks find it much harder to shine with a wet ball, which you should consider when weighing up individual player props.
  • Statistics show that games played in cold or snowy conditions produce fewer points, so think about that when considering an over/under bet.

🎾 Tennis

Let’s look at how weather affects betting odds in tennis. Outdoor tournaments will not proceed in rain unless the court has a retractable roof, but heat and wind can have a major weather impact.

  • On hotter days, the ball will travel faster through the air, making it likely that more aces will be served.
  • However, in windy conditions, the ball toss can be harder to control, making aces less likely to occur.
  • If a tournament is played in extreme heat, a player may struggle to recover fully from a gruelling match in time for the next round.

🏎️ Formula One

Few sports are more at the mercy of conditions than Formula One, where the weather impact can be significant, particularly when it rains.

  • Rain radically alters the condition of the track, which means teams have to change tires, adding significant uncertainty to the race outcome.
  • If you have an accurate weather forecast and know which teams are using hard, soft, or medium tyres, you can predict how the next few laps will pan out.
  • Watch the changing weather conditions and be ready to move fast when you see an edge in the in-play markets

🎮 Sports least affected by weather

For many sports, the impact of weather on betting behavior is minimal because they are played indoors. It is unlikely that esports, basketball, or hockey odds will fluctuate if it starts raining.  

However, there may be ways in which the weather can impact a game. If a team has had a long delay to its flight caused by bad weather, or flooding has forced it to change route to the venue, that might reduce its chances of winning. 

Live betting: Reacting to weather in real time

Knowing how weather affects betting odds can help your decision-making, particularly when it comes to in-play wagering. By keeping a close eye on the weather, you may be able to get an edge and make your play before the odds move.

You may notice, for instance, that it is particularly windy at a golf championship or an NFL game. There will be a weather impact on the scoring at both, so you may find some value on the over/unders.

A rain delay to an MLB game or a tennis match could make a difference in the momentum of the action, or give a tired player a chance to recover. Similarly, when the heat is intense, you may anticipate that exhausted players on the tennis court or in an NFL game will perform less well in the latter stages. 

How to factor weather into your betting strategy

Once you have understood the link between weather and sports betting, there are some simple steps you can take to apply that knowledge to your wagering strategy.

  • Use reliable forecasts. By finding the best apps and platforms with accurate readings of upcoming conditions, you can be ahead of the game with your live bets.
  • Study the movement of lines. Watch how certain sportsbooks move their odds in response to changing weather conditions. In time, you will see which ones overreact and which move more slowly.
  • Match the weather to the team. Do your research and find out which teams record better results in rain, snow, or wind. An NFL team with a strong rushing game, for instance, may thrive in the rain.

Once you know how weather affects different sports, you can apply that knowledge appropriately to every game when it’s clear the conditions will have an impact.  

Final thoughts: Weather as a bettor’s edge

Every bettor is looking for an edge, and an understanding of the link between weather and sports betting can be extremely valuable to the smart gambler. There are distinct, consistent patterns around how weather affects different sports that the well-informed bettor can use to their advantage. 

Source reliable forecast data and combine it with your analysis of a team’s tactics and recent form to aid your decision-making. This is particularly key to live betting, where knowledge of the likely weather impact before the odds move can give you an opportunity to pounce. 

And remember, please bet responsibly at all times when you are wagering on sports.  

FAQs

Which sports are most affected by weather?

Sports that rely on good conditions but can be played in bad, such as NFL, Formula One, baseball, and tennis, will always feel the greatest weather impact. Extreme heat or cold, snow, rain, or wind can make a significant and sudden difference to the way a game or race plays out. 

Should I always bet the “under” when bad weather is expected? 

Not necessarily; it depends on the market you’re playing in. You may expect fewer total points in an NFL game when the weather turns hostile, which makes an under bet the right play. But there may be prop markets, such as total rushing yards, that make an over bet the right way to go when the quarterback is less inclined to pass.
