Training in hot weather: sun safety for summer tournaments and pre-season

Why heat is a real coaching hazard, not just discomfort

Cold and wet get most of the "is it safe to train" attention in grassroots football, but heat causes more serious medical incidents in youth sport than most coaches expect — heat exhaustion, and in rare cases heat stroke, both happen on ordinary pitches during pre-season (July-August) and at all-day summer tournaments, not just in extreme heatwaves.

The risk is highest exactly when coaches are least prepared for it: pre-season starts in the hottest part of the year, and tournament days mean 4-6 hours of continuous sun exposure for players rotating through matches and coaches who never leave the touchline.

Recognising heat exhaustion early

Watch for:

• Excessive sweating, or in more advanced cases, sweating that suddenly stops
• Pale, cool, or clammy skin (different from the flushed look of normal exertion)
• Dizziness, headache, or nausea
• Cramping, especially in the legs
• A player who suddenly underperforms or seems "switched off" — often the first sign parents and coaches miss

Act immediately if you see these: stop the player, move them to shade, loosen extra clothing, and give small regular sips of water. Call for medical help if symptoms don't improve within 20-30 minutes or if a player becomes confused, stops sweating, or loses consciousness — those are heat stroke red flags and need emergency treatment, not a rest on the bench.

Adjusting the session for heat

Treat 30°C+ (86°F+), especially with high humidity, as the point to actively change your plan, not just "push through":

• Shorten work blocks and add a mandatory shaded water break every 15-20 minutes
• Move high-intensity running work to the coolest part of the session (start or very end), and use the middle for technical/possession work at lower intensity
• Run team talks and drink breaks in shade, not standing in direct sun
• Schedule sessions for early morning or evening where the fixture list allows it
• Above roughly 32-33°C with no shade available anywhere on site, cancelling or moving indoors is the safer call — this isn't being soft, it's basic duty of care

Hydration: little and often, not one big bottle

As a rough guide, players should take on 150-250ml every 15-20 minutes during hot sessions — more for older and adult players doing intense work. Thirst is already a lagging indicator of dehydration, so scheduled breaks matter more than waiting for players to ask. Remind parents the night before a hot session or tournament day: send players in already hydrated, not relying on catching up once they arrive.

Sun protection for players

Sunscreen (parents' responsibility, applied before arrival and reapplied at half-time on tournament days), light-coloured breathable kit where the format allows it, and encouraging players to use shade during any downtime between matches all help. A wide-brim hat or cap during warm-ups and breaks (not during play, obviously) is worth normalising at younger age groups especially.

Sun protection for coaches — the part everyone forgets

Coaches get more sun exposure than most players, not less. A single training session is 60-90 minutes of standing in the open; a tournament day is 4-6 hours pitch-side with no rotation, no bench, and often no shade near the touchline. Treat sun protection as standard kit rather than an afterthought:

• Wraparound sunglasses that actually stay on while you're moving, shouting instructions, and looking up and down the pitch all day
• UPF-rated clothing or sun sleeves for the arms — a full day in short sleeves at a July tournament adds up fast, and sleeves mean you're not choosing between sunburn and overheating in a long-sleeve top
• A hat with genuine brim coverage, not just a cap peak

Tournament day survival kit

For coaches and players spending a full day on an exposed pitch: sunscreen (SPF 30+, reapplied at half-time), a refillable water bottle per player, a pop-up shade shelter or team gazebo if the venue allows it, a cool box with ice packs for cramps and minor knocks, and a spare set of light kit for players who overheat in the wrong layers.

When to postpone or cancel

Postpone or move indoors if: temperature is forecast above roughly 32-33°C with no shade on site, there's an official heat-health warning in effect, or you don't have enough water/shade to run scheduled breaks safely. As with cold and wet weather, this isn't about being soft — it's the same duty-of-care judgement call, just for the opposite end of the thermometer.
