Golf in the heat can be safe and enjoyable with a little planning. Book early morning or late afternoon tee times, drink water before you feel thirsty and keep sipping every hole or two, add electrolytes on long rounds, wear light-colored, breathable clothing with a wide-brim hat, and apply broad-spectrum sunscreen of SPF 30 or higher, reapplying at the turn. Use shade and carts where possible, and carry spare gloves and a towel for sweaty grips. Most importantly, know the warning signs of heat illness, such as dizziness, headache, nausea, cramps and weakness, and stop to cool down right away. Confusion, fainting or very hot skin can signal heat stroke, a medical emergency.
Why heat matters on the golf course
A round of golf often lasts four hours or more, with long stretches in direct sun and little shade. Walking the course, carrying a bag and concentrating on each shot all add physical strain. In hot, humid conditions, the body works harder to cool itself through sweating, and fluid losses can build up without golfers noticing. Heat can also affect focus, decision-making and swing tempo, so managing it well improves both safety and performance.
Heat checklist
| Area | Tip |
|---|---|
| Tee time | Early morning or late afternoon |
| Hydration | Drink regularly every hole or two; add electrolytes on long rounds |
| Clothing | Light colors, moisture-wicking fabric, wide-brim hat |
| Sun | SPF 30 or higher sunscreen, reapplied at the turn; sunglasses |
| Shade | Wait in shade, use a cart or umbrella |
| Equipment | Spare gloves and a towel for sweaty grips |
| Food | Light snacks such as fruit, nuts or sandwiches |
Hydration
Start hydrating before your round by drinking water in the hours leading up to your tee time. On the course, drink small amounts regularly, such as a few sips every hole or two, rather than waiting until you feel very thirsty. On long, hot rounds, especially if you sweat heavily, sports drinks or electrolyte tablets can help replace sodium lost in sweat. Avoid relying on alcohol or large amounts of sugary drinks, which do not hydrate well. Pale yellow urine is a simple sign of adequate hydration.
Clothing and sun protection
Choose light-colored, loose-fitting, moisture-wicking shirts and shorts or trousers that meet your course’s dress code. A wide-brim hat protects your face, ears and neck better than a cap, although many golfers wear caps with sunscreen on exposed areas. Apply a broad-spectrum sunscreen with SPF 30 or higher about 15 minutes before playing and reapply every two hours or after heavy sweating, often at the turn. Sunglasses protect your eyes from glare and ultraviolet light. Cooling towels or neck wraps can also help.
Managing your round
- Use shade. Stand in the shade while waiting to hit and between shots.
- Consider a cart. Riding reduces exertion on very hot days, or use a push cart instead of carrying.
- Pace yourself. Walk at a comfortable speed and take breaks when needed.
- Keep grips dry. Use a towel and rotate gloves to maintain a secure hold.
- Eat light snacks. Fruit, nuts and simple sandwiches keep energy steady without feeling heavy.
Warning signs of heat illness
| Condition | Common signs | What to do |
|---|---|---|
| Heat cramps | Painful muscle cramps, heavy sweating | Stop, rest in shade, drink fluids with electrolytes |
| Heat exhaustion | Heavy sweating, dizziness, headache, nausea, weakness, cool clammy skin | Stop playing, move to shade or air conditioning, loosen clothing, sip fluids, cool the body; seek medical help if symptoms worsen or do not improve |
| Heat stroke | Confusion, slurred speech, fainting, very high body temperature, hot skin; sweating may be present or absent | Call emergency services immediately and cool the person rapidly |
Heat stroke is a medical emergency. While waiting for help, move the person to a cool place and cool them quickly with water, ice packs or wet towels, especially at the neck, armpits and groin. Do not give fluids to someone who is confused or unconscious.
How heat affects the ball and course
Warm air is less dense than cool air, so the ball tends to fly a little farther on hot days. Firm, dry fairways add extra roll, and greens may become faster as they dry out. Some golfers find they need to club down slightly. Heat can also affect the golfer: fatigue may shorten your swing or change your tempo late in the round, so pay attention to how your body feels.
Acclimatizing to hot weather
The body adapts to heat over time. Golfers who move to a hot climate or face the first heat wave of summer often feel the effects more strongly than those who have been playing in warm weather for weeks. Gradual exposure helps: start with nine holes or range sessions during cooler parts of the day, then build up to full rounds over one to two weeks. As the body acclimatizes, sweating becomes more efficient and heart rate stays lower at the same effort. Even acclimatized players still need to hydrate and protect themselves from the sun.
Keeping your equipment in good shape
Heat affects gear as well as golfers. Leaving golf balls in a very hot car trunk for long periods is best avoided, and extreme heat can soften some grips and damage electronics such as rangefinders and phones. Keep spare gloves in a dry pocket of your bag, since sweat can make gloves slippery and wear them out quickly. Rotating two or three gloves during a round keeps your grip secure. Wipe grips with a damp towel and dry them to remove sweat and sunscreen residue.
Playing strategy in the heat
On hot days, conserve energy by keeping your routine efficient and avoiding unnecessary walking. Plan your shots to stay out of deep rough and bunkers, which require more effort to escape. Because the ball may fly and roll farther, adjust club selection and aim for the safe side of greens when the ground is firm. Staying patient and focused matters, since heat can lead to fatigue and impulsive decisions late in the round.
Step by step: preparing for a hot round
- Check the forecast, including heat index and humidity.
- Book an early or late tee time when possible.
- Hydrate in the hours before your round.
- Pack water, electrolytes, snacks, sunscreen, a hat and a towel.
- Dress in light, breathable clothing.
- Plan to ride or use a push cart on very hot days.
- Agree with playing partners to watch for signs of heat illness.
Who should take extra care
Older adults, young children, people with heart or lung conditions, people who take certain medications and those not used to hot weather are more vulnerable to heat illness. If you fall into one of these groups, take extra precautions, consider shorter rounds or cooler times, and talk with your doctor about playing in the heat.
Common mistakes
- Waiting until you feel very thirsty to drink.
- Relying on alcohol or sugary drinks for hydration.
- Skipping sunscreen reapplication.
- Ignoring early symptoms such as dizziness or headache.
- Carrying a heavy bag on the hottest days.
