Imagine: the key match of the season is on the line. Your bet is hanging in the balance, and suddenly a downpour begins on the field, changing the trajectory of the ball and the speed of the players. At such a moment, understanding how weather affects sport becomes not just a useful skill, but a real advantage. Unlike spectators, bettors need to not only predict the weather, but also assess how its vagaries will affect the results, odds and, ultimately, their bets on bookies online.
In this article, we’ll look at five key weather factors that can turn the game around and how to factor them into your analysis.
Wind: The Invisible Player on the Field
Wind is the master of unexpected scenarios. In football, gusts knock long passes off course, in tennis they distort the trajectory of the serve, and in golf they turn a precise shot into a lottery. However, the most striking example is baseball. A strong headwind slows the ball down, causing it to ‘bounce,’ which is advantageous for pitchers with curveballs. A tailwind, on the other hand, speeds up the ball, increasing the chances of home runs.
Example for bettors: In 2019, an MLB game between the Chicago Cubs and the Colorado Rockies was played in winds of up to 40 km/h. Sportsbooks set high odds on totals, but experienced players, taking into account the wind direction, increased their bets on individual outfielders’ performance. The result: 8 out of 10 long hits landed outside the field, bringing unexpected losses to the favourites.
Tip: Study the history of the stadium. Open arenas (such as Wrigley Field) are more prone to wind.
Keep an eye on the forecast an hour before the match — the wind direction and strength can change dramatically.
Rain: When the Field Becomes an Ally or a Traitor
A wet lawn is not just mud. In rugby, it slows down ball passing; in football, it increases the number of mistakes made by defenders; and in American football, it turns fourth down into Russian roulette. However, the main victim of rain is goal statistics. UEFA research shows that during heavy rain, the number of shots on target decreases by 15-20%, and the penalty conversion rate drops to 54% (compared to 75% in dry weather).
An example for bettors: In the 2021 Premier League match between Liverpool and Manchester United, it started raining in the second half. The bookies’ odds for a total of less than 2.5 shots on goal rose sharply, but those who knew that Manchester United had scored 60% of their goals in the second half of the season bet on “both teams to score” — and won.
Assess the teams’ line-ups. Teams that focus on dribbling (such as Barcelona) lose in slippery conditions.
When betting on statistics (corners, fouls), keep in mind that referees award more set pieces in the rain.
Heat: The Hidden Enemy of Endurance

Temperatures above 30°C not only pose a risk of heatstroke, but also factor into tactics. In tennis, players shorten rallies, in football they slow down, and in marathons, 80% of records are set at temperatures between 10-15°C. For bettors, the key indicator is the Wet Bulb Globe Temperature (WBGT), which combines heat, humidity and solar radiation. For example, when the WBGT is above 32, NFL matches often end with a lower total due to frequent breaks for hydration.
An example for bettors: At the 2020 US Open in New York, with a WBGT of 29°C, the average number of games per set for the top 10 tennis players fell from 9.3 to 6.7. Bets on ‘more than 20.5 games per match’ failed, although before the tournament such an outcome seemed safe.
When betting on long events (matches without timeouts), lower your expectations for totals.
Monitor substitutions: in hot weather, coaches are more likely to bring in fresh players in the second half.
Cold: When Muscles Become Enemies
Sub-zero temperatures change physiology: muscles lose elasticity, the risk of injury increases, and passing accuracy in football decreases by 12-18%. In ice hockey, it would seem that the cold is an ally, but the ice becomes harder, increasing the puck’s bounce. For bettors, this means that teams from warmer regions (such as Spanish clubs in the Europa League) often lose away games in Scandinavia in winter.
Example for bettors: In a 2022 Champions League match, Bayern Munich faced Zenit in St. Petersburg at -10°C. The German club, accustomed to controlling the ball, made 20% more mistakes, and Zenit’s odds of winning rose from 5.00 to 4.20 on the day due to the weather forecast.
Analyse the match schedule. Teams that play twice a week are less able to adapt to sudden drops in temperature.
When betting on the first half, keep in mind that it takes longer to warm up in the cold, so the opening minutes are often sluggish.
Humidity: The Unseen Conductor of the Game
High humidity (above 70%) increases the load on the cardiovascular system, causing athletes to make more mistakes due to fatigue. In cricket, this leads to a decrease in bowlers’ speed, and in basketball, to a loss of accuracy in three-point shots. In handball, however, humid air improves ball grip.
Example for bettors: At the 2022 World Cup in Qatar, matches with humidity of 80%+ showed an increase in substitutions in the 65th minute and later. Bettors who bet on goals in the last 25 minutes increased their ROI by 18% thanks to weather report analysis.
Conclusion: Weather as a Forecasting Tool
To be successful in betting, it is not enough to know the team line-ups or goal statistics. The weather is an independent player that can overturn the logic of the odds. Follow these rules:
- Always check the WBGT and wind speed 1-2 hours before kick-off.
- Compare historical data: how the team has performed in similar conditions.
- Use sudden weather changes to find ‘arbitrage’ odds.
Remember: bookies Pakistan do not always adjust their lines quickly when weather reports change. Your task is to stay one step ahead.
