Understand before you pack
Thailand weather, region by region — and why the rainy season isn't what you think.
Thailand is a warm, tropical destination essentially year-round. The real planning question isn't "is it good weather?" — it almost always is — but which region and month suit what you want to do, since the north, the centre and the two south coasts each run on a different calendar.

How we estimate
- For each day we look at what happened on the same dates over the past years in each region.
- Days with the same kind of weather are grouped, so you see when it changes.
- Reliability = how often past years really looked like the estimate shown.
These are estimates built from 10 years of past weather records (2016–2025) at one reference point per region. They are not a forecast: nothing is confirmed and the weather of your trip can differ. Check the live forecast shortly before you travel.

WMO climate normals 1991-2020 (CLINO)
The three-season pattern (mainland and north)
Most of Thailand — the north, the north-east and the central plains including Bangkok — follows a fairly consistent three-season year. The two south coasts diverge from this pattern; see the zone breakdown further down.
-
November to February
Cool and dry
The most popular travel window: lower humidity, little rain, warm days and noticeably cooler evenings, especially in the north where highland nights can drop into single digits. Clear skies make this the best time for mountain views and city sightseeing alike.
-
March to May
Hot season
The hottest, driest stretch of the year, with April typically the peak — this is also when Thailand celebrates Songkran (the water festival) in mid-April. Afternoon heat is intense; plan outdoor activity for morning or evening and stay hydrated.
-
June to October
Rainy (monsoon) season
The south-west monsoon brings the year's rainfall to most of the mainland, usually as short, heavy afternoon or evening showers rather than continuous rain. Landscapes are lush and green, prices and crowds are lower, and mornings are often sunny.
By zone
- North (Chiang Mai, Chiang Rai, Pai, Mae Hong Son) Cool and dry
-
Cooler highland evenings, a dry burning season to plan around.
Follows the mainland three-season pattern closely, with the most distinct cool season of anywhere in Thailand — mountain evenings can feel genuinely cool, even chilly at altitude. One regional quirk worth knowing: February to April is often hazy from agricultural burning, which can affect air quality and mountain views more than rain does. Rainy months (roughly June–October) bring lush, misty landscapes and fewer crowds at temples and trekking routes.
- Central Thailand & Bangkok Cool and dry
-
The classic three-season year; short evening downpours in the wet months.
Bangkok and the central plains are the textbook three-season case: a comfortable cool season (Nov–Feb), a hot and humid March–May, and a wet season from roughly May to October where a daily late-afternoon shower is common but rarely lasts long. City life continues normally through the rainy season — just carry a light rain jacket and expect the odd flooded street after a heavy burst.
- Gulf coast (Koh Samui, Koh Phangan, Koh Tao) Rainy (monsoon) season
-
Runs opposite to the rest of the country — wettest around October–December.
This is the zone that surprises people: the Gulf islands face the opposite monsoon to the rest of Thailand, so their wettest months are roughly October to December, while the mainland's June–September monsoon barely touches them — that stretch is often one of the sunniest times to visit Koh Samui. If travelling in November or early December, build in flexibility for short but sometimes heavier showers and occasional rough boat crossings.
- Andaman coast (Phuket, Krabi, Koh Lanta, Koh Phi Phi)
-
Follows the south-west monsoon; roughest seas May–October.
Broadly follows the mainland's monsoon timing — wet season roughly May to October, dry and sunny November to April. The main practical impact here is at sea rather than on land: the south-west monsoon can bring choppier waters and stronger currents, so island-hopping, diving and snorkelling trips are easiest to plan November–April, and some smaller boat routes reduce service or pause in the wettest weeks.
Common misconception
The "rainy season" is not a washout
Many travellers picture months of non-stop grey skies and cancel or reschedule trips over it. In most of Thailand, the reality is milder: a hot, sunny morning, an intense but short afternoon or evening downpour lasting anywhere from twenty minutes to a couple of hours, then clear skies again. Full days of continuous rain do happen, but they are the exception, not the rule.
- Showers are typically short and localised, not all-day events — plan around them rather than avoiding the season entirely.
- Temperatures stay warm and pleasant throughout — the rainy season is not a cold season, humidity is simply higher.
- Rain also cools the air and clears haze/dust, and vegetation, waterfalls and rice terraces are at their greenest and most dramatic.
- "Rainy season" is not one single season for the whole country — it falls in different months on the Gulf coast versus the Andaman coast versus the mainland (see the zones below).
Live rain and storm alerts
The tracker below flags when a zone currently shows an active rain, shower or thunderstorm signal, alongside the next few days' outlook — useful for deciding whether to head out now or wait out a short shower.
Seasonal patterns reflect general long-term climate knowledge for Thailand (Thai Meteorological Department / Tourism Authority of Thailand consensus) and can vary from year to year.
