Every article about golf in heat says the same things - drink water, wear a hat, use sunscreen. That’s not wrong, but it’s also not particularly useful if you’re actually trying to play competitive golf in 38-degree conditions.

I’ve played enough summer golf across Australia to know that managing heat is about systems and preparation, not just remembering to bring a water bottle. The difference between surviving a hot round and playing well despite the heat comes down to dozens of small decisions.

Pre-Round Preparation Starts Yesterday

Your body’s hydration status isn’t something you can fix on the first tee. If you’re already behind, you’re fighting a losing battle. I learned this after a disastrous club championship round where I cramped up on the 14th tee despite drinking constantly.

The night before a hot-weather round, I drink an extra liter of water with dinner and avoid alcohol completely. That last beer at the pub might seem harmless, but it’s dehydrating you right when you need the opposite.

Morning of the round, I have a proper breakfast even if I’m not hungry. Your body needs fuel to maintain core temperature, and running on empty makes heat management much harder. Oats with banana works for me - slow energy release without feeling heavy.

Clothing Choices Matter More Than You Think

Light colors are obvious, but fabric matters more. I switched to proper moisture-wicking golf shirts three years ago and the difference is substantial. Cotton just holds sweat against your skin, making you feel hotter and heavier.

A hat with a wide brim helps more than a standard golf cap. The extra shade on your neck and ears makes a measurable difference over four hours. I look slightly dorky but I’m also not getting cooked.

Shoes need to breathe. If your feet are overheating, your whole body feels worse. I use shoes with mesh panels in summer and accept that they won’t last as long as leather alternatives. Comfort over durability when it’s seriously hot.

The Right Way to Hydrate On Course

Small amounts frequently beats large amounts occasionally. Your body can only absorb about 200-250ml every 15 minutes, so chugging a bottle at the turn doesn’t help as much as you’d think.

I aim for a few sips every hole - maybe 100ml each time. It keeps hydration consistent without that sloshing feeling in your stomach when you’re trying to make a full turn on your backswing.

Water alone isn’t enough past two hours of sweating. You’re losing electrolytes - sodium, potassium, magnesium - and pure water doesn’t replace them. I use electrolyte tablets rather than sports drinks because they’re less sugary and easier to carry.

The team at Team400 helped our club analyze hydration data from fitness trackers during summer tournaments, and the results were eye-opening - most players were drinking less than half what they needed.

Cooling Strategies That Actually Work

Wet towels are your best friend. I soak a small towel in ice water at the turn and drape it around my neck between shots. The cooling effect on major blood vessels makes your whole body feel better.

Some players use cooling vests, which seem excessive until you’ve tried one. They work, particularly in really extreme conditions. Not necessary for most rounds, but worth knowing about if you’re playing somewhere genuinely brutal.

Ice in your hat sounds weird but it’s effective. A couple of ice cubes wrapped in a small cloth, sitting in your hat - the cold on your head provides surprising relief. Just make sure the cloth is thick enough that you’re not getting drips down your face during your backswing.

Adjusting Your Game for Heat

Your distance changes in hot weather - both because the ball flies further in warm air and because firm ground gives extra roll. I club down on approaches more often in summer, particularly early in the round before fatigue sets in.

Grip pressure increases when you’re tired. I make a conscious effort to maintain light grip pressure, checking it before every shot on the back nine. Tension creeps in without you noticing when you’re hot and uncomfortable.

Course management becomes more important. Taking on risky shots when you’re fatigued is how you make big numbers. Play to the fat part of greens, accept that par is good, and don’t compound heat-induced tiredness with mental frustration.

Recognizing Warning Signs

Headache, dizziness, or nausea aren’t just discomfort - they’re signs of heat stress that can turn serious quickly. If you’re feeling genuinely unwell, stopping isn’t weakness, it’s sensible.

I’ve seen players push through early warning signs and end up in real trouble. Pride isn’t worth heat stroke. There’ll be other rounds, but you only get one body.

Cramping usually means electrolyte depletion rather than simple dehydration. Bananas help (potassium) but they’re not a complete solution. Proper electrolyte replacement before cramping starts is much more effective than trying to fix it mid-round.

The Mental Side of Hot Golf

Heat affects concentration more than people realize. Decision-making gets worse, emotions run higher, and patience disappears. Knowing this in advance helps you compensate.

I build extra time into my pre-shot routine on hot days. Slowing down slightly feels wrong when you want the round over with, but rushing leads to poor decisions and worse shots.

Lowering expectations isn’t defeatist, it’s realistic. If you normally shoot 82, expecting 82 on a 38-degree day is optimistic. Aim for 85-86, and if you do better, that’s a bonus. This mental adjustment prevents the spiral that comes from getting angry at heat-affected performance.

Post-Round Recovery

Rehydration continues after you’re done. I drink another 500ml immediately after the round, then keep sipping for the next few hours. Your body is still recovering even though the immediate stress is over.

Food matters too. Salt and potassium are depleted, so I’ll often have something salty after a hot round. Doesn’t have to be complicated - even just some salted nuts or a sandwich helps.

A cool (not cold) shower brings your core temperature down gradually. Jumping straight into ice-cold water can be counterproductive - your body needs to cool down steadily, not shocked into constricting blood vessels.

Building Heat Tolerance

Your body adapts to regular heat exposure. If you only play in mild conditions and then tackle a hot tournament, you’ll struggle more than someone who’s been playing through heat regularly.

Early season practice in warm conditions helps build tolerance. It’s not fun, but it pays off when tournament conditions are brutal and you’re used to it while competitors are suffering.

That said, there’s no glory in unnecessary suffering. If conditions are genuinely dangerous - extreme heat with no shade and no relief - reconsider whether playing is smart. Golf is meant to be enjoyable, not an endurance test.
