Rainy-season golf in Chiang Mai is worth it if you play mornings. From June to October the rain falls as short afternoon storms, not all-day washouts, so the course is lush, tee sheets are near-empty, and all-in rates start around ฿1,950. Tee off early and you rarely lose a round.
The catch is a real one, and we will not hide it: September and October are the wettest months of the year, and the burning-season haze that some travellers try to dodge sits at the other end of the calendar. This is a guide to when green-season golf pays off, what it actually costs, and how we schedule around the weather. For the dry-peak comparison, see our best time for golf in Chiang Mai guide.
When is the rainy season for Chiang Mai golf?
The green or rainy season runs April 1 to October 31, the opposite of the November-to-March dry peak. It is the cheapest, quietest, most short-notice-bookable stretch of the golf year.
The season is not one weather pattern. April and May are hot, with 35C afternoons and early storms, and they overlap the tail of burning season. June, July and August are the sweet spot: warm mornings, reliable but brief afternoon rain, deep-green fairways. September and October are the true wet months before the dry season returns. Chiang Mai's climate records put September at about 190 mm of rain across roughly 20 rainy days, easing to 112 mm over 14 days in October (weather-and-climate.com, accessed 2026-09-10).
Will rain actually stop me playing?
Rarely, if you tee off early. Rain here arrives as short, heavy late-afternoon storms, usually 30 to 90 minutes, then clears. Mornings are commonly dry and the greenest of the year.
The monsoon pattern is a gift to a golfer who plans around it. Storms build with the afternoon heat and break late, so the playable window is the morning. Book the first or second tee slot, aim to finish by early afternoon, and most days you beat the rain entirely (Climates to Travel, accessed 2026-09-10). Thai courses also play through light rain: your caddie holds the umbrella and keeps your grips dry. Only lightning stops play, on a horn, until the cell passes. A well-drained layout like Chiangmai Highlands recovers within the hour, so a morning-first rotation rarely loses a round.
How much cheaper is green-season golf?
Green-season all-in rates start near ฿1,950 and top out around ฿3,400 at the best-conditioned course. You also get near-empty fairways and one-to-two-day booking lead times instead of weeks.
All-in here means green fee plus the mandatory caddie fee plus cart. The Gassan courses out toward Lamphun are the value floor. Gassan Panorama, one of Thailand's longest layouts at 7,761 yards, runs about ฿1,950 all-in in green season. Gassan Legacy, the flattest and easiest of the group, is ฿1,950 by day and ฿1,650 under floodlights. Highlands, the region's best-conditioned course, sits near ฿3,400 all-in (฿2,250 green, ฿400 caddie, ฿750 cart), with its cart and caddie fees confirmed on the course's own rate card (Chiangmai Highlands rates, accessed 2026-09-10). Rates move every season, so confirm the live number at booking.
| Period | Weather | Crowds | Rates | Verdict |
|---|---|---|---|---|
| Apr-May | Hot 35C+, early storms, haze tail | Light | Green-season low | Playable but check air quality |
| Jun-Aug | Warm, brief afternoon rain | Light | Green-season low | Best value window of the year |
| Sep-Oct | Wettest, ~190mm Sept | Very light | Lowest | Great value, morning tee times only |
| Nov-Mar | Cool, dry, clear | Heavy | Peak rack rate | Best conditions, dearest, book weeks ahead |
What are the real numbers?
Green season stacks up as low rates, real rain and thin crowds. Here is the sourced picture rather than the brochure version.
What is the honest downside?
Softer ground, casual water and the odd cart-path-only day. September and October can wash out an afternoon, and some courses aerate greens in the low season.
The rain that keeps fairways lush also leaves them soft, so you get less roll and the occasional puddle in a low fairway. Drainage varies a lot between courses. Better-drained layouts play within an hour of a storm; flatter ones hold water longer. The bigger watch-item is maintenance: low season is when several courses schedule greens aeration, which leaves temporarily sandy, bumpy putting surfaces. Always ask whether a course has recent or planned greens work before you commit a round to it. And on a September afternoon, accept that a suspended round is a real possibility, not a freak event.
Which courses suit a wet-season trip?
Well-drained, better-conditioned courses that recover fast, plus the floodlit ones that let you dodge a rained-off afternoon by playing at night.
Highlands drains well and holds its condition through the wet, which is part of why it commands the top green-season rate. The Gassan courses add a genuine rainy-season trick: floodlit night golf. If a storm eats your morning, a dry evening under lights is a fair recovery. Value-hunters can pair a cheap round at Mae Jo, the closest resort course to the city at around 20 minutes, with a look at our best value golf course rundown. Whatever the mix, keep the tee times early and the transport pre-booked.
What should I pack for rainy-season golf?
A compact umbrella, a couple of spare gloves, quick-dry layers and shoes you do not mind getting wet. Your caddie covers the on-course basics, so pack light and pack smart.
Most Thai courses supply a large umbrella on the cart and your caddie manages it, so you do not need a full rain suit for a short storm. What actually saves a round is keeping your hands dry: bring two or three gloves in a zip bag and swap the moment one gets damp, because a wet glove is what ruins your grip, not the rain itself. A small towel clipped inside the bag and a waterproof cover for the clubs handle the rest. Wear breathable, quick-dry layers rather than heavy waterproofs, since the heat is the bigger discomfort at 30C-plus humidity. Waterproof or mesh golf shoes and a spare pair of socks in the bag mean a soaked low fairway does not follow you to lunch. Sun cream and insect repellent still earn their place: the sun is fierce between storms and standing water brings mosquitoes.
Should I book a package or pay as I go?
For one round, book direct: green-season rates are already discounted and tee times are easy. For three or more rounds, a package earns its keep, mostly through folded-in private transfers.
The package math is different in the wet season. When rates are already low and tee sheets are open, a single direct-booked round is often the cheapest route, and we will tell you so. Where a trip package pays off is logistics: an afternoon storm plus a wet road is safer with a pre-booked private driver than a last-minute Grab hunt with a golf bag. A package folds in those transfers, tee-time coordination and on-the-ground support, so a suspended round gets rescheduled rather than lost.

Can you actually play golf in Chiang Mai during the rainy season?
Yes, most rainy-season days are playable if you tee off early. From June to October the rain arrives as short, heavy afternoon storms, usually 30 to 90 minutes, not all-day drizzle. Mornings are commonly dry and the course is at its greenest. Book the first or second tee slot, aim to finish by early afternoon, and you will rarely lose a full round. September and October are the wettest months, so keep your plans flexible on those two and treat a washed-out afternoon as the exception, not the rule.
How much cheaper is green-season golf in Chiang Mai?
A lot. Green-season all-in rates (green fee plus caddie fee plus cart) start around ฿1,950 at the Gassan courses, sit near ฿2,850 at Mae Jo through an agent, and reach about ฿3,400 at best-conditioned Highlands. High-season rack rates run materially higher and tee times are harder to secure. You also get shorter lead times: many courses take a booking one or two days out in green season, versus weeks ahead for a peak-season weekend. Always confirm the live rate at booking, since prices change every season.
Which months are the rainy season for Chiang Mai golf?
The green or rainy season runs April 1 to October 31, but the character shifts across it. April and May are hot with early storms and overlap the tail of burning season. June to August brings reliable afternoon rain with playable mornings. September and October are the wettest, with September averaging about 190 mm across roughly 20 rainy days. Rain almost always falls late in the day, so the golf calendar in green season is a morning calendar. High season, the dry peak, is November 1 to March 31.
What happens to my tee time if it rains?
Thai courses play through light rain, and your caddie holds an umbrella and keeps your grips dry. Heavy lightning triggers a horn and a suspension until it clears, then play resumes. Policies on rain checks and cart-path-only rules vary by course and are not standardised, so confirm the specific course's wet-weather and refund policy when you book. As an enquiry-driven operator we build a morning-first schedule and keep a flexible slot, so a storm that suspends one afternoon rarely costs you a round across a multi-day trip.
Are the courses in worse condition in the rainy season?
Fairways are usually at their lushest and greens roll true, because the rain feeds the turf. The trade-offs are softer ground, casual water in low spots, and the occasional cart-path-only day. Some courses also schedule greens aeration in the low season, which leaves temporarily sandy or bumpy greens, so it is worth asking whether a course has recent or planned maintenance before you commit. Drainage differs a lot between courses: the better-drained layouts recover within an hour of a storm, the flatter ones hold water longer.
Should I book a package or pay as I go for a green-season golf trip?
For a single round in green season, booking the course direct is often cheapest, because rates are already discounted and tee times are easy to get. A package earns its keep across three or more rounds, when folded-in private transfers matter most: an afternoon storm and a wet road are safer with a pre-booked driver than a last-minute ride hunt. CMGT Golf is enquiry-driven, so we send a quote rather than a fixed shelf price. Tell us your dates and we build the morning-first schedule around the forecast.
