Tennis Weather in the UK

Q: What wind speed is too much for tennis?

Wind above 15 mph (24 km/h) starts to noticeably affect ball flight and serve accuracy. Above 20 mph, lobs become very difficult to control and high-tossed serves are affected. Above 25 mph, consistent ball striking is difficult for most players and the game becomes frustrating. Professional tournaments are rarely played in sustained winds above 30 mph. For recreational players, winds above 20 mph are challenging; above 30 mph, play is effectively compromised.

Q: What temperature is too hot or too cold for tennis?

The ideal temperature range for tennis is 15–25°C. Below 10°C, the ball loses pressure faster and becomes harder and less bouncy, while cold muscles are more injury-prone — a proper warm-up is essential. Above 30°C, the risk of heat exhaustion increases significantly during long matches. Court surfaces (especially hard courts) can be 10–15°C hotter than the air temperature in direct sun, so a 28°C day can feel like 38–40°C at court level. The ATP and WTA have heat stress rules for professional play above 32°C wet-bulb globe temperature.

Q: How wet is too wet for a tennis court?

Any standing water on a court makes it unsafe to play. Even after rain stops, hard courts can remain slippery for 30–60 minutes until they dry. The critical danger zones are the painted lines, which have very little grip when wet. Most UK clubs have a policy of not allowing play on wet hard courts regardless of whether rain is still falling. Clay courts drain faster but the top layer becomes slippery mud. Grass courts should be avoided until the surface is fully dry and firm — typically several hours after rain.

Wind speed effects on tennis

Wind is the most disruptive weather factor in tennis. Even modest breezes affect the serve toss, lob control and ball flight — and crosswinds on an open court can make consistent play nearly impossible.

Wind speed	Beaufort scale	Verdict	Effect on play
0–10 mph	Bft 1–2 (Light air/breeze)	Very Doable	Negligible effect. Serve toss stable, ball flight true. Ideal conditions.
11–15 mph	Bft 3 (Gentle breeze)	Very Doable	Slight drift on lobs. Flat serves unaffected. Most players adapt easily.
16–20 mph	Bft 4 (Moderate breeze)	Take Care	Serve toss requires adjustment. Lobs and drop shots become unreliable. Ball skids unpredictably with the wind.
21–28 mph	Bft 5 (Fresh breeze)	Take Care	High-toss serves very difficult. Slice shots exaggerated. Playing into the wind makes power shots float. Strategy must adapt.
29–38 mph	Bft 6–7 (Strong/Near gale)	Best Avoided	Consistent play extremely difficult. Ball control largely lost. Increased injury risk from off-balance movement.
38+ mph	Bft 8+ (Gale)	Best Avoided	Dangerous. Flying debris, structural risk to canopies and fencing. Do not play.

Serving into the wind vs with the wind

Wind direction matters as much as wind speed. Serving into the wind reduces pace but improves control — it kills slice and kick serves. Serving downwind gives more pace but the toss is harder to control and flat serves can fly long. Cross-court winds are the hardest to adapt to, as the ball drifts laterally in a way that is difficult to anticipate or plan for.

Wet courts — when to stop playing

Rain transforms a tennis court into a hazard. The moment precipitation starts, conditions deteriorate rapidly — especially on hard courts where there is no absorption.

Hard courts in rain

Hard court surfaces — acrylic, asphalt and concrete — have almost no grip when wet. The painted lines are especially dangerous, becoming as slippery as ice during lateral movement. The LTA and the majority of UK clubs advise ceasing play immediately when rain starts on hard courts. This is not overcaution — ankle and knee injuries from slipping are common when players continue on wet hard courts.

After the rain stops

A hard court can remain dangerous for 30–60 minutes after light rain, and longer after heavier rain. Most surfaces need to be fully dry to the touch before resuming. In overcast conditions with no wind, drying takes longer — a court that looks dry can still be slippery. The painted service boxes and baselines dry last. Use a squeegee if one is available; otherwise wait. For indoor or covered courts, this is not an issue.

Grass courts in rain

Grass courts become extremely slippery very quickly in rain. Even light drizzle is enough to make grass dangerous for rapid directional changes. Grass also suffers surface damage when played on wet — divots and mud patches form rapidly, which can cause unpredictable ball bounces and ankle hazards even after the court dries.

Clay courts in rain

Clay courts absorb light rain better than hard or grass surfaces, and play can sometimes continue through very light drizzle. However, the top layer becomes slippery mud once the rain is significant, and the ball becomes visibly heavy and loses its bounce. Most clay court clubs draw the line at moderate rain (2mm/hr or more). Post-rain, clay courts need rolling and relining — typically done by groundstaff before play resumes.

Temperature guide for tennis

Temperature affects both player safety and the ball itself. Pressurised tennis balls behave differently in cold conditions, and court surfaces (especially dark hard courts) can be far hotter than the air temperature suggests.

Below 5°C

Cold — injury risk

Muscles and tendons are stiff and injury-prone. Ball loses bounce and feels hard. Thorough warm-up essential.

5°C – 14°C

Cool — take care

Manageable with proper warm-up. Ball may feel slightly dead. Wear layers you can remove.

15°C – 25°C

Ideal

Best conditions for both performance and comfort. Ball behaviour is optimal.

26°C – 32°C

Warm — hydrate

Court surface may be 10–15°C hotter than air. Carry water. Take breaks in shade between sets.

Above 32°C

Heat risk

Heat exhaustion risk on long matches. Professional tournaments suspend play at 32°C WBGT. Shorten sessions.

UV and long matches

A typical competitive match lasts 90 minutes or more. At UV index 6 (moderate-high), which is common in the UK from May to August, sun damage can occur in 30 minutes without protection. Apply SPF 30+ before play — particularly to the back of the neck and arms. A cap helps protect the face without affecting peripheral vision. UV index is at its highest between 11am and 3pm.

Tactics for playing tennis in wind

If conditions are breezy but playable, adjusting your tactics can make a significant difference to your enjoyment and performance.

Serve adjustments

In a crosswind, toss the ball slightly upwind so it drifts back to your strike zone. Lower your toss height in strong wind to reduce drift time. Consider using a slice serve into the wind (it becomes more vicious) and a flat first serve with the wind (where pace naturally increases). Avoid the kick serve in strong crosswinds — the topspin interacts unpredictably with the wind.

Groundstroke strategy

Playing into a headwind, add more topspin to keep the ball in — flat shots float long. Playing downwind, use flatter shots and aim deeper. Slice backhand shots are excellent in wind — the low trajectory and backspin make them more predictable than topspin groundstrokes. Avoid ambitious cross-court angles in crosswinds; the ball drifts further than expected.

Mental adaptation

Wind makes the game feel unfair because both players experience it differently on each side. Accept that the wind is part of the conditions — players who adapt their expectations and strategy for the wind will always out-perform those who try to ignore it. Change ends every two games; this is partly why — it equalises the wind advantage over a set.

Frequently asked questions

Can you play tennis in light rain? ▼

Technically yes, but it is generally not advisable. Even light rain makes hard courts extremely slippery — the painted lines and acrylic surface become as treacherous as ice when wet. Wet lines are a significant slip hazard, particularly during lateral movement. On clay, light drizzle can be managed briefly, but the ball becomes heavy. On grass, any rain makes the surface slippery immediately. The LTA advises stopping play as soon as courts become wet.

What wind speed is too much for tennis? ▼

Wind above 15 mph starts to noticeably affect ball flight and serve accuracy. Above 20 mph, lobs become very difficult to control and high-tossed serves are affected. Above 25 mph, consistent ball striking is difficult for most players. For recreational players, winds above 20 mph are challenging; above 30 mph, play is effectively compromised.

What temperature is too hot or too cold for tennis? ▼

The ideal temperature for tennis is 15–25°C. Below 10°C, the ball loses pressure and becomes harder and less bouncy, while cold muscles are more injury-prone. Above 30°C, the risk of heat exhaustion increases during long matches. Court surfaces can be 10–15°C hotter than the air temperature in direct sun, so a 28°C day can feel like 38–40°C at court level.

Is it safe to play tennis in a thunderstorm? ▼

No — stop play immediately if you hear thunder or see lightning. Tennis courts are open, flat surfaces with no protection from lightning, and metal racket frames can conduct electricity. The LTA guidance is to stop play at the first sign of lightning and seek shelter in a solid building. Wait at least 30 minutes after the last thunder before resuming play.

How wet is too wet for a tennis court? ▼

Any standing water on a court makes it unsafe. Even after rain stops, hard courts can remain slippery for 30–60 minutes. The painted service boxes and baselines dry last. Most UK clubs have a policy of not allowing play on wet hard courts regardless of whether rain is still falling. Clay courts drain faster but become slippery mud when saturated. Grass courts should be avoided until fully dry — typically several hours after rain.
