Playing Sport in Hot, Humid Weather: Hydration and Safety Tips for Golf, Padel and Pickleball | Sharp by Design
Share
Summer is when Australian sport comes alive. Early-morning rounds, evening padel sessions, weekend pickleball with friends. But when the temperature climbs and the air turns heavy with humidity, playing sport stops being just a matter of fitness and starts being a matter of safety.
Heat and humidity together place extra strain on your body. Understanding why, and knowing what to do about it, helps you play better, recover faster and avoid serious heat-related illness. This guide covers how hot, humid conditions affect you, how to hydrate properly, what to wear, how to protect your skin and how to recognise the warning signs.
This article is general information only and is not medical advice. If you have a medical condition, take medication, are pregnant, or are unsure whether it is safe for you to exercise in the heat, speak to your doctor first.
Why heat and humidity make sport harder
When you exercise, your muscles produce heat, and your body needs to get rid of it. It does this mostly by sweating. As sweat evaporates from your skin, it carries heat away. That cooling system works well in dry heat.
Humidity changes the equation. When the air is already full of moisture, sweat does not evaporate as readily. It drips off you instead of cooling you, so your body temperature climbs faster even though you are sweating heavily. Your heart works harder, you tire sooner and you are more at risk of dehydration and heat illness.
That is why a 30 degree day with high humidity can feel and behave much harder on your body than a 30 degree day that is dry. It also explains why the same session can feel easy one day and exhausting the next.
Several factors raise your risk further:
• Not being used to the heat
• Being dehydrated before you start
• Poor sleep or being unwell
• Alcohol the night before
• Some medications
• Older age, or very young age
• Intense exercise, or long sessions with no breaks
1. Check the conditions before you play
Do not rely on the temperature alone. Look at the forecast for humidity, the UV index and wind, and check for any heat warnings in your area. If you can, plan your session for the cooler parts of the day, typically early morning or later in the evening, and avoid the middle of the day when the sun and temperature peak.
If conditions are extreme, rescheduling is always a valid choice. No round, match or social game is worth risking your health.
2. Start well hydrated
Hydration starts well before you step onto the court or tee. In the day or two before a hot session, drink fluids regularly and eat normal, balanced meals. Do not try to catch up all at once just before playing.
A simple check is the colour of your urine. Pale yellow, like straw, usually indicates you are well hydrated. Dark yellow suggests you need more fluids. In the couple of hours before you play, drink a glass or two of water, then let your body clear any excess before you start.
3. Drink regularly during play
Thirst is a late signal. By the time you feel thirsty, you may already be somewhat dehydrated. Aim to sip regularly through your session rather than gulping a large amount at once. On the golf course, drink at every hole or two. In padel or pickleball, drink between games and at changeovers.
Most people need a few hundred millilitres in each hour of exercise, and in hot, humid conditions more. How much you need varies with your size, how hard you play, how much you sweat and the conditions, so use your own experience as a guide. One practical approach is to weigh yourself before and after a session. Weight lost during exercise is mostly fluid, and large losses suggest you should drink more next time.
Water or electrolytes?
For sessions around an hour or shorter, water is usually enough. For longer sessions, or if you are a heavy sweater, an electrolyte drink can help replace the sodium and other minerals you lose in sweat. You can spot a heavy sweater by white salt marks on dark clothing or a salty taste on your skin.
Do not overdo it
Drinking more than you need is not better. Taking in very large volumes of plain water over a long period can dilute the sodium in your blood, a condition called hyponatremia, which can be serious. Drink to your needs, not to a target number.
4. Dress for the heat
Your clothing is a tool for staying cool. Choose pieces that are:
• Lightweight. Heavy fabrics trap heat.
• Breathable. Mesh and moisture-wicking fabrics let air circulate and help sweat evaporate.
• Light in colour. White and pastel shades reflect more sunlight than dark colours.
• Loose enough to move air. A relaxed fit allows airflow without clinging when damp.
A mesh jersey like our Bajada Padel Jersey, made from breathable polyester mesh with a relaxed fit and extended length, suits hot courts. On the golf course, a clean white golf polo that fits well, neither clinging nor flapping, makes a difference. Our guide to building a capsule golf wardrobe covers the essentials.
Add a trucker cap with a mesh back to shade your face while letting heat escape. For more ideas, see our guide to golf course dress codes in Australia.
5. Protect your skin
Sunburn does more than hurt. It impairs your skin’s ability to cool you and increases your long-term skin cancer risk. Australia’s familiar advice still applies: slip on protective clothing, slop on sunscreen, slap on a hat, seek shade and slide on sunglasses.
• Apply broad-spectrum SPF 50+ sunscreen about 20 minutes before you head out.
• Reapply about every two hours, and after heavy sweating.
• Cover often-missed spots such as the back of your neck, ears, tops of your feet and the backs of your hands.
• Wear a cap or hat and sunglasses.
• Seek shade whenever you pause, between holes, games or sets.
6. Acclimatise gradually
Your body can adapt to heat, but it takes time. Over roughly one to two weeks of repeated exposure, you begin to sweat earlier, sweat more efficiently and lose less salt. If you are not used to hot weather, perhaps because you have been travelling or the first heatwave has just arrived, ease in. Play shorter sessions, lower the intensity and add time gradually.
7. Pace yourself and take breaks
You do not have to play at full pace in the heat. Slow down, shorten your session, or play fewer games. Take regular breaks in the shade or somewhere air-conditioned.
Cooling strategies help too:
• Sip cold water.
• Keep a cool, damp towel around your neck.
• Splash water on your face and arms.
• Refresh with ice in your bottle or an esky.
On the golf course, consider walking in the shade where you can, using a cart for part of the round, and not rushing between shots.
8. Know the warning signs
Knowing how to spot heat illness early could save a life, yours or someone else’s.
Early signs (heat exhaustion)
• Heavy sweating
• Headache
• Dizziness or light-headedness
• Nausea
• Muscle cramps
• Unusual tiredness or weakness
• Fast pulse
• Cool, clammy or pale skin
What to do: Stop playing immediately. Move to a cool place, lie down with feet raised if you feel faint, sip water, loosen or remove excess clothing and cool your body with damp cloths, a fan or ice packs on the neck, armpits and groin. If symptoms do not improve quickly, seek medical advice.
Emergency signs (heat stroke)
• Confusion, slurred speech or strange behaviour
• Fainting or collapse
• Hot, red skin, with sweating that may have stopped
• Very high body temperature
• Seizures
Heat stroke is a medical emergency. Call 000 immediately. While you wait, move the person into shade, remove excess clothing and cool them as fast as possible with cold water, wet towels or ice packs. Do not give fluids to someone who is confused or not fully alert.
Look out for others
Sport in the heat is a team effort. Check on your playing partners, especially older players, children and anyone who looks flushed, unusually quiet or unsteady. Encourage breaks and make it normal to say you need one.
