Thailand plays golf all year. The courses never close for winter, the grass stays green, and you can tee off in shorts in January. But “open year-round” is not the same as “equally good year-round.” The country runs on a tropical monsoon calendar, and the difference between a December morning and a September afternoon is the difference between a comfortable round in shirt-sleeves and a rain delay under a thunderstorm shelter.
This guide breaks the Thai golf year into its three real seasons, gives you verified weather patterns for each, and hands you a month-by-month table so you can match your trip to the conditions you want. It also covers a point most golf brochures skip: Thailand is a big country, and the “best month” in Bangkok is not the best month in Chiang Mai or on the Andaman coast. If you are still deciding where to base yourself, our https://gonggolf.com/golf-in-thailand/ covers the regions in detail, and the https://gonggolf.com/golf-in-thailand/cost/ guide shows how prices swing with these same seasons.
Thailand’s Three Golf Seasons at a Glance
Central and eastern Thailand — the Bangkok and Pattaya golf belt where most visitors play — runs on three broad seasons driven by the monsoon:
- Cool, dry season (roughly November to February) — the peak. Least rain, lowest humidity, most comfortable temperatures, clearest skies. This is prime golf time, and everyone knows it, so courses and resorts are at their busiest and priciest.
- Hot season (roughly March to May). The dry weather largely holds, but daytime highs climb into the mid-30s Celsius and beyond. Playable, especially early morning, but demanding by midday. Crowds thin and rates ease.
- Green / rainy season (roughly June to October). The southwest monsoon brings the year’s heaviest rain, peaking around September. Courses are lush and green, rates are lowest, and rain often comes as short heavy bursts rather than all-day washouts — but you must plan around it.
Those windows shift by a few weeks from year to year and from region to region, so treat the month boundaries as guidelines rather than hard lines.
Cool, Dry Season (November–February): The Peak
If you want the single best answer to “when should I play golf in Thailand,” it is roughly December to mid-February. During these months the northeast monsoon brings drier, more stable air to central Thailand. In Bangkok, average rainfall drops to around 13 mm in January and just a few millimetres in December — often only one or two rainy days for the whole month. Mean temperatures sit near 28 C, with daytime highs around 32–33 C and pleasant mornings.
The practical payoff for golfers:
- Comfortable mornings. A 7:00 to 8:00 am tee time in December or January is genuinely enjoyable — cooler air, lower humidity, and you can walk 18 holes without wilting.
- Dependable conditions. Full-day washouts are rare, so a tightly packed golf itinerary is far less likely to be derailed.
- Clear skies and firm-but-fair courses. The best time of year for scenery and photos, and fairways run truer than in the soaked months.
The trade-off is crowds and cost. This window overlaps Thailand’s peak tourist season and the Northern-Hemisphere winter escape, so tee sheets fill fast — morning slots between about 7:00 and 10:00 go first — and green fees and resort rates sit at their annual high. Book tee times and accommodation well ahead, especially over the December holidays and Chinese New Year. Our https://gonggolf.com/golf-in-thailand/cost/ guide explains the high-season premium in detail, and if you are mapping out a full trip, the https://gonggolf.com/golf-in-thailand/trip-planner/ walks through how to sequence courses and tee times around this demand.
Hot Season (March–May): Quiet Courses, Early Tee Times
From March through May, central Thailand stays mostly dry but heats up markedly. Bangkok’s mean temperature climbs toward 30.5 C in March and about 31.5 C in April — the hottest month of the year — with daytime highs commonly in the mid-to-upper 30s Celsius and high humidity building ahead of the monsoon. Rainfall creeps up too, from around 40 mm in March to roughly 90 mm in April as pre-monsoon showers begin.
Golf in this season is entirely doable, but it changes how you play:
- Tee off at first light. The earliest available slot — around 6:00 to 7:30 am — is the comfortable window. By late morning the heat is serious.
- Hydrate and take a cart. Most visitors ride rather than walk in these months, and caddies (near-universal in Thailand) will keep you supplied with water and shade; see our https://gonggolf.com/golf-in-thailand/caddies/ notes for how the caddie system works.
- Enjoy the space and value. Crowds thin noticeably after the February peak, tee sheets open up, and rates soften — good news for flexible golfers who don’t mind the heat and stick to mornings.
April is also the month of Songkran, the Thai New Year water festival, with the national public holidays falling on 13–15 April. It is a wonderful cultural experience but can affect transport, staffing, and course availability around these mid-April dates, so factor it into your plans.
Green / Rainy Season (June–October): Lush, Cheap, and Underrated
The southwest monsoon defines this season. In Bangkok, monthly rainfall climbs from roughly 155 mm in June to a peak around 335 mm in September, spread across 18 to 21 rainy days a month at the height of the monsoon in September and October. Temperatures actually ease slightly from the hot-season peak — mean values around 29–30 C — because cloud cover moderates the daytime highs.
It sounds off-putting, but the rainy season is more golf-friendly than the raw numbers suggest, and it is genuinely popular with value-focused travellers:
- Rain often comes in bursts. Much of the monsoon rain falls as intense afternoon or evening downpours and thunderstorms rather than continuous all-day rain. A morning round frequently finishes before the heaviest weather arrives.
- Courses look their best. This is when Thailand’s fairways and gardens are at their most vivid green.
- Lowest prices and open tee sheets. Green fees and packages hit their annual low, and you can often book on short notice. The https://gonggolf.com/golf-in-thailand/cost/ guide quantifies just how much you can save.
The risks are real and worth planning for: lightning will suspend play (Thai courses take storms seriously and will clear the course), the odd day is a full washout, and softer ground means more casual water and slower-running fairways. Build a buffer day or two into a rainy-season itinerary, favour early tee times, and consider booking flexible or refundable tee times. Note that late season into November can still deliver heavy rain in some years as the monsoon retreats.
Month-by-Month Snapshot (Central Thailand / Bangkok Golf Belt)
The table below uses long-term climate averages for Bangkok, representative of the Bangkok–Pattaya golf region where most visitors play. “Crowds” and “price level” reflect typical golf-tourism demand. Treat weather figures as climatological averages, not a forecast — always check conditions close to your trip.

If you play the popular Bangkok-area courses such as Thai Country Club or Ballyshear Golf Links (both just outside Bangkok, in the Chachoengsao and Samut Prakan areas), or head down to the Gulf coast for Siam Country Club near Pattaya, this Bangkok calendar is a close guide — the eastern Gulf coast follows a very similar dry-season (December to April) and wet-season (May into November) rhythm, with December and January the driest months of all.
Regional Nuance: North vs. Coast
The three-season model above holds for central and eastern Thailand, but two regional patterns are important enough to change your planning.
Northern Thailand (Chiang Mai and around): watch the burning season
The north is cooler than Bangkok in the peak months — Chiang Mai’s nights in December and January can drop to around 15–16 C, and it’s the most pleasant golf climate in the country during that window, with January and February averaging only about 10 mm of rain. But the region has a distinct and serious drawback later in the dry season.
From roughly February through April, farmers across northern Thailand and neighbouring countries burn crop stubble and forest, and the surrounding mountains trap the smoke. Air quality can deteriorate sharply — ground and satellite monitoring recorded “unhealthy” to “very unhealthy” PM2.5 levels across Chiang Mai during the 2026 burning season, including days in early and mid-April 2026 when the city topped global pollution rankings, with the haze typically peaking around March and April and easing as the rains return in May. For golfers, this means the north is at its best in November, December, and January, and the late-dry-season haze months are best avoided if air quality matters to you or anyone in your group. Chiang Mai’s hottest months (March to April) also push daytime highs toward 35–37 C.
The Andaman (west) coast, Phuket: a more pronounced wet season
Phuket and the Andaman coast share broadly the same November-to-April dry season as the rest of the country, and those months deliver the classic clear-sky, comfortable golf conditions. The difference is the monsoon: the southwest monsoon hits the west-facing coast hardest, so the May-to-October wet season here is the most pronounced in Thailand, with heavier, more sustained rain and rough surf. The dry-season window on the Andaman coast is therefore especially worth protecting — aim for November through February, and treat the shoulder months of April and November as transitional, when showers can still be abundant.
So, When Should You Go?
A quick way to decide, depending on what you value most:
- Best all-round conditions: December to mid-February. Comfortable, dry, reliable — worth the crowds and premium prices. Book early.
- Best value with still-good weather: March, and the shoulder weeks of November and early December. Fewer crowds, softer rates, mostly dry — just tee off early to beat the heat.
- Lowest cost, green courses, flexible plans: June to October. Accept the risk of rain delays, build in a buffer day, play in the mornings, and enjoy the savings.
- Heading north (Chiang Mai): stick to November to January and avoid the February-to-April burning/haze season.
- Heading to Phuket / the west coast: commit firmly to the November-to-February core of the dry season.
Whatever month you choose, an early tee time is the single best habit for golf in Thailand year-round — it beats the heat in the hot months and dodges the afternoon storms in the wet ones.
