How to Keep Cool While Playing Golf in Hot Weather

Playing a great round of golf on a scorching hot day is just as much a mental and strategic challenge as it is a physical one. Beating the heat isn't about simply enduring it, it's about having a game plan to keep your body cool and your mind sharp from the parking lot to the 18th green. This guide will walk you through the practical, coach-approved strategies you need to not just survive a hot day on the course, but to actually play well and enjoy it.

Before You Even Reach the First Tee: Smart Preparation

Your battle against the heat doesn't start when you feel the sun beating down on the first fairway. It starts the day before. The smartest golfers prepare for extreme conditions before they even a pack their bag, giving themselves a massive advantage.

Hydration Starts Yesterday

One of the biggest mistakes golfers make is trying to hydrate during the round. By the time you feel thirsty, you're already behind the curve and your performance is suffering. True hydration for a 4-5 hour round in the sun begins 24 hours in advance. Make a conscious effort to drink plenty of water throughout the day leading up to your tee time. Think of it as filling up your body's a reservoir. If you start the round with a full tank, you only have to focus on topping it off. While water is great, consider adding an electrolyte tablet or drink to your pre-round routine to pre-load the essential minerals you're about to sweat out.

Timing is Everything: Pick the Right Tee Time

This might seem obvious, but it’s the single most effective way to avoid the worst of the heat. The sun is at its most intense and punishing between 11 a.m. and 3 p.m. If you have the flexibility, book the first tee time of the day and you'll likely be finishing up as the temperature really starts to climb. Conversely, a late afternoon "twilight" round can be fantastic, as you'll play during the cooler, golden hours. If you're stuck with a mid-day tee time, all the following tips become even more important.

Dress for Success (and Survival)

Your clothing is your first line of defense against the sun and heat. Ditch the old cotton polos and dark colors, which trap heat and moisture. Modern golf apparel is your best friend here. Here's what to look for:

  • Light Colors: White, light grey, and pale blue reflect sunlight, whereas black and navy blue absorb it.
  • Moisture-Wicking Fabric: Look for tech fabrics like polyester or nylon blends designed to pull sweat away from your skin and help it evaporate, creating a cooling effect.
  • UPF Protection: Many modern golf shirts come with a Ultraviolet Protection Factor (UPF) rating. A UPF 50 shirt acts like sunscreen for your torso.
  • The Right Hat: A baseball cap is better than nothing, but a wide-brimmed "bucket" or "sombrero" style hat is far superior. It provides 360-degree shade, protecting your ears and the back of your neck - two spots that get exposed and sunburned constantly.

Pack Your "Cool" Bag

Think of your golf bag as your support vehicle. A little extra preparation here pays off immensely. Along with your a clubs and balls, make sure you pack these heat-beating essentials:

  • A Large Insulated Water Bottle: Fill it with ice and water right before you leave. It will stay cold for much longer than a standard plastic bottle. Aim to have at least 64 ounces with you.
  • Two Towels: One is for you, one is for your gear. Keep one towel damp and cold (you can re-wet it at water stations or from your ice bottle) to wipe your face and neck. The other stays dry for your grips and hands.
  • High-SPF Sunscreen: Apply it liberally a 30 minutes before your round and, most importantly, re-apply it at the turn. A spray-on type can be quick and easy to apply mid-round.
  • Healthy, Light Snacks: Bananas (potassium), oranges (hydration), or a small bag of almonds can give you a clean energy boost without weighing you down.

On-Course Tactics: Staying Cool While You Play

Once you’re on the course, the game shifts to conservation - conserving your energy, your coolness, and your focus. Small, consistent actions are what separate those who wilt on the back nine from those who finish strong.

Hydrate The Right Way

Chugging a whole bottle of water on the 4th tee won't do you much good. Your body can only absorb so much at once. The key is consistent sipping. Make it a rule: after every tee shot, take a few good sips of water. This keeps your system steadily replenished. Alternate between plain water and a sports drink or an electrolyte packet mixed into your water, especially on the back nine. This replaces the salt and potassium you lose through sweat, which is vital for preventing cramps and mental fog. And an important reminder: caffeine and alcohol are diuretics that will a dehydrate you faster. Save the beer for the 19th hole.

Use the Shade Strategically

Pretend you're a tactician whose greatest weapon is the shade. A few degrees of temperature difference and getting out of the direct sun, even for a minute at a time, makes a huge difference over 18 holes.

  • When driving a cart, park it in the shade of a tree, not in the middle of the fairway.
  • Walk along the tree lines to your ball instead of down the sunny center.
  • While waiting for your partners to play, stand under a tree. Don’t just stand in the sun.

Each of these small moments is a chance for your body to cool down and recover. They add up significantly.

The Magic of a Wet Towel

This is a timeless pro tip for a reason: it works wonders. Take that damp towel from your bag and drape it over the back of your neck. The main arteries that supply blood to your brain are close to the surface of the skin on your neck. Cooling this area has an immediate and powerful effect on your overall body temperature and how you feel. It can snap you out of that hazy, overheated feeling in seconds.

Adjust Your Expectations (and Your Pace)

You are simply not going to have the same amount of physical energy in 95-degree heat as you do on a perfect 70-degree day. Accept it. Don’t fight it. Trying to swing out of your shoes on every shot will just wear you down faster. This is the perfect time to choose a riding cart over walking. Conserve your energy between shots so you can commit to the swing when it matters. Take an extra club and make a smoother, 80% swing. Your body will thank you, and your scores probably will, too.

Think Cool, Play Cool: Your Mental Game in the Heat

Heat doesn’t just drain your body, it drains your brain. Mental errors - poor decisions, loss of focus, frustration - spike when your core temperature rises. Protecting your mental game is the final piece of the puzzle.

Accept the Conditions, Don't Fight Them

Whining about the heat is a waste of precious mental energy. Complaining doesn’t lower the temperature, it just deepens your negativity and takes your focus off the shot at a hand. Before the round, simply tell yourself, "It's going to be hot today, and that's okay. I have a plan for it." By accepting the conditions, you can focus your energy on executing your strategy - seeking shade, hydrating, and making good decisions.

How Heat Affects Your Shot Decisions

Fatigue breeds sloppy choices. After three hours in the sun, you are more likely to pull the hero club or try a risky shot you have no business playing. Heat can also impact ball flight, warm, humid air is less dense, meaning the ball may fly a bit further than usual. Acknowledging this is step one. Step two is simplifying your strategy. Aim for the fat part of the green. Take the safer club. Prioritize making a solid, committed swing over a powerful one. A tired, lazy swing is a recipe for a big number.

Know the Warning Signs

This is about more than golf, it's about your well-being. You have to be able to recognize the signs of heat-related illness. Be aware of these symptoms in yourself and your playing partners:

  • Heat Exhaustion: Heavy sweating, clammy skin, dizziness, headache, nausea, rapid pulse, and fatigue.
  • Heatstroke (Medical Emergency): High body temperature, confusion, slurred speech, a loss of consciousness, and skin that is hot but could a be either dry or damp.

If you start to feel genuinely unwell, stop playing immediately. Get into the shade, drink cool water, and seek help. No score is worth risking your health.

Final Thoughts

Playing golf in the heat is a learnable skill, blending smart preparation before your round with disciplined tactics during it. By controlling your hydration, what you wear, and how you use the course to your advantage, you can protect your body and mind from the draining effects of the sun, freeing you up to play your best.

When fatigue sets in on those blazing hot days, making smart, simple decisions becomes that much harder.
