Playing golf in Thailand's heat is a solved problem: tee off at first light, drink 500ml to 750ml of fluid an hour, use your caddie's umbrella for shade, and avoid the March to May peak when April highs hit about 38C. Do that and Chiang Mai plays comfortably almost year round. Here is the full playbook, from tee-time timing to the warning signs to watch for.
How hot does it actually get on a Chiang Mai golf course?
Chiang Mai runs hot most of the year, with April highs averaging about 38C and even cool-season afternoons reaching 28C to 32C. The fairway feels hotter than the forecast because there is no shade.
Chiang Mai has three seasons that decide how a round feels. The cool, dry season runs November to February, when highland courses sit at 15C to 22C early and highs land at 28C to 32C. The hot season is March to May, peaking in April at around 38C average maximum (weather-and-climate.com, accessed 2026-09-18). The green season is June to October: humid, with short afternoon storms but mornings that are usually playable.
The number on your phone understates the course. An open fairway with no tree cover, radiant heat off the cart path, and Thailand's humidity all push the felt temperature well past the shade reading. That is why timing matters more than the raw forecast.
What time should I tee off to beat the heat?
Take the first or second tee time of the day, around 6:30am to 7:00am. You finish the front nine before the sun has bite and clear 18 holes by late morning, before the 1:00pm to 3:00pm peak.
Health agencies agree on this one point: schedule outdoor exercise for the cooler morning or evening hours (CDC, accessed 2026-09-18). On a golf course that means an early tee time is the single highest-impact decision you make. In cool season a 7:00am start has you in the clubhouse for lunch. In hot season it is the difference between a pleasant round and a survival exercise.
The downside of dawn golf is honest: peak-season weekend tee times at the best-conditioned courses sell out days ahead, so the early slots go first. Book early, or let an operator hold the block. For the full timing breakdown, see our guide to the best tee times for Chiang Mai golf.
How much water do I need for 18 holes in the heat?
Plan for 500ml to 750ml of fluid per hour of play in the heat, roughly 2 to 3 litres across a round. Sip every 15 to 20 minutes and do not wait until you feel thirsty.
Golf Australia's hot-weather guidelines put the target at about 3ml per kg of body mass every 15 to 20 minutes, or 500ml to 750ml per hour, with an extra 500ml to 750ml added for every hour played in real heat (Golf Australia Hot Weather Guidelines, accessed 2026-09-18). For a four-hour Chiang Mai round in April, that is a serious volume of fluid.
Two practical notes. First, do not rely on water alone for a long hot round; add electrolytes, because over-drinking plain water can cause low blood sodium. Second, every course sells cold water and most carts carry a cooler, so topping up mid-round is easy. Alcohol at the turn is the classic mistake, it speeds dehydration.
What should I wear to stay cool?
Light-coloured, loose, moisture-wicking fabric, a wide-brim hat or cap, sunglasses and high-SPF sunscreen. Dress codes still apply, so it must be a collared shirt and tailored shorts or trousers.
The heat advice and the course dress code point the same way. Loose, lightweight, light-coloured clothing keeps you cooler, and it happens to fit the collared-shirt, soft-spike standard every Chiang Mai course enforces. No denim, no sport shorts, no sleeveless shirts. See our Chiang Mai golf dress code guide for the exact rules per course.
Add a cooling towel you can soak at every water station, a spare shirt for the back nine, and sunscreen you reapply at the turn. A round in April can cost you two shirts. That is normal, not a sign you are doing it wrong.
Which months are the worst for heat?
March to May, peaking in April. Highs average about 38C and the burning season overlaps the same window. November to February is the cool, dry, comfortable season and the easiest golf of the year.
| Period | Typical high | Heat comfort | Verdict |
|---|---|---|---|
| Nov-Feb (cool) | 28-32C | Comfortable, cool mornings | Best golf, book ahead |
| Mar-May (hot) | up to 38C | Hard, plus haze | Dawn or night only |
| Jun-Oct (green) | 31-34C | Humid, morning storms | Great value, play early |

Can I play at night to skip the heat entirely?
Yes. Several Chiang Mai courses run floodlit night golf, which removes the daytime heat problem completely. Expect cooler air, a slower pace, and rates that can undercut a daytime round.
Night golf is the most underrated heat tactic in the region. Gassan Legacy Golf Club lights its course and lists an all-in night rate in the region of 1,500 to 1,800 baht, cheaper than its daytime rate. Summit Green Valley runs floodlit night golf too, and the in-city Star Dome Golf Club is built for after-dark nine-hole rounds. You trade mountain views for comfortable temperatures.
The trade-off: not every course lights every night, and floodlight schedules move with the season, so confirm at booking. Night rounds also play slower under lights. For a heat-averse golfer, that is a fair price.
How does the caddie help me manage the heat?
Your caddie is a built-in heat manager. Caddies are mandatory in Thailand, one per golfer, and they carry an umbrella for shade, hand you cold water, and wipe you down with a chilled towel between shots.
Every Thai course assigns one caddie per player, no opt-out, and on a hot day that rule works in your favour. The caddie holds the umbrella over you while you wait, sets the pace so you are not baking in full sun, cleans your ball, and keeps you moving efficiently. The caddie fee is about 300 to 400 baht at Chiang Mai courses, and a tip of 400 to 600 baht per round is expected, handed over in cash at the bag drop after the round. Say "khob khun khrap" or "khob khun kha".
If you want the full norms, our Chiang Mai caddie culture and tipping guide covers it. Courses closest to the city, like Mae Jo at about 20 minutes out, also cut your transfer time in the heat.
What are the warning signs of heat exhaustion?
Heavy sweating, muscle cramps, dizziness, weakness, nausea, and cold clammy skin or a rapid pulse. If they appear, stop, get to shade or air conditioning, loosen clothing, and sip cool water.
Heat exhaustion is the body's response to losing too much water and salt through sweat, and the symptoms are muscle cramping, heavy sweating, weakness, dizziness, thirst and nausea (CDC, accessed 2026-09-18). The fix is simple and immediate: move to shade or the air-conditioned clubhouse, loosen or remove excess clothing, sip cool water, and use a cool towel or shower to bring your temperature down.
Does the burning season matter as much as the heat?
Yes, and it overlaps the heat. Roughly mid-January to mid-April, agricultural burning pushes Chiang Mai's air quality index past 150, and past 300 on the worst days. Check it daily and carry an N95.
The hot months carry a second problem beyond temperature. From around March, air quality drops hard: in the worst weeks PM2.5 readings can exceed 300, and Chiang Mai regularly ranks among the world's most polluted cities during the burn. Heat you can plan around with an early tee time. Smoke you cannot outrun on an open course. Check IQAir or aqicn each morning, carry an N95, and read our burning season golf guide and air purifier guide before you travel in those weeks. If the AQI is bad, shifting the trip or the destination beats playing through it.
Should I book a package for hot-weather rounds?
A package helps most in the heat because the operator secures the dawn tee times that sell out first, folds air-conditioned private transfers into the price, and manages the schedule around the cool end of the day.
The hot-weather advantage of an enquiry-based golf package is logistical. We hold the early tee-time blocks that individual bookers miss, run air-conditioned private transfers so you are not standing at a Grab pickup in the sun, and sequence courses so you play the most exposed layout on your coolest morning. CMGT Golf is enquiry-driven, so we send a quote and confirm with a deposit rather than a fixed shelf price.
Be honest about when it does not pay: a single dawn round you can book direct is often cheaper than any package. The package math works when you are playing several rounds and want the timing and transfers handled. Compare options across the full course directory, or a shorter trip like the Weekend Warrior or Northern Value itinerary.

Frequently asked questions
What time should I tee off to avoid the heat in Chiang Mai?
Book the first or second slot of the day. Most Chiang Mai courses open tee sheets around 6:30am to 7:00am, and that early window lets you play the front nine before the sun has real bite. From November to February you finish 18 holes around 11:00am to 11:30am, well before the 1:00pm to 3:00pm peak. In the hot months of March to May, an early tee time is not optional, it is the only comfortable way to play. The alternative is a twilight round from about 3:30pm, or floodlit night golf. We build every itinerary around the cool end of the day.
How much water should I drink during a round in Thailand?
Plan for 500ml to 750ml of fluid per hour of play in the heat, so roughly 2 to 3 litres across an 18-hole round, per Golf Australia's hot-weather guidance. Sip every 15 to 20 minutes rather than gulping at the turn, and do not wait until you feel thirsty. Add an electrolyte tab or a sports drink if you are sweating heavily for more than an hour. One honest caution: over-drinking plain water can cause low blood sodium, so balance water with electrolytes on the hottest days. Every course sells cold water and most carts carry a cooler.
Which months are too hot for golf in Chiang Mai?
March through May is the hot season, with April the peak. Average highs reach about 38C in April, and the afternoon on an exposed fairway feels hotter. It is playable if you tee off at dawn and stop by late morning, but it is the least comfortable window of the year. March and April also overlap the burning season, when air quality drops sharply. If your only option is those months, play early, keep rounds short, and consider night golf. November to February is the cool, dry, comfortable season and the reason most golfers come.
Do Chiang Mai courses have night golf to beat the heat?
Yes. Several courses run floodlit night golf, which sidesteps the daytime heat entirely. Gassan Legacy offers an all-in night rate in the region of 1,500 to 1,800 baht, cooler and quieter than a midday round. Summit Green Valley and Star Dome also light their courses after dark. A night round trades the mountain views for a comfortable temperature and a slower pace, which suits players who struggle in tropical heat or who land on an evening flight. Confirm floodlight schedules and current rates at booking, since not every course lights every night and start times shift by season.
How does the caddie help with the heat?
Your caddie is your heat-management partner. Caddies are mandatory at every Thai course, one per golfer, and they carry an umbrella that doubles as portable shade between shots. They will hand you cold water, wipe you down with a chilled towel, and set the pace so you are not standing in full sun longer than needed. The caddie fee runs about 300 to 400 baht at Chiang Mai courses, with a tip of 400 to 600 baht per round expected in cash at the end. On a hot day, a good caddie is worth every baht for the shade alone.
