Thailand’s weather varies little in temperature but swings between dry and wet seasons. The cool season (November–February) offers the most comfortable conditions, while March–May is hot, and June–October brings monsoon rain.

What is the weather like in Thailand each month?

Thailand has three distinct seasons. From November to February, the northeast monsoon brings cooler, drier air; daytime highs average 28–32°C, with low humidity. March to May is the hot season, with temperatures reaching 35–40°C, especially in April. June to October is the rainy season, driven by the southwest monsoon; heavy but often short downpours are common, and humidity stays high (70–90%). Coastal areas and islands can see more rain, while northern regions are cooler year-round.

When is the best time to visit Thailand?

The best time for most travellers is the cool season (November–February), when skies are clear and temperatures are pleasant. For beach holidays, avoid the rainy season (June–October) on the west coast (Andaman Sea) because of rough seas and frequent storms. The east coast (Gulf of Thailand) has a shorter rainy period, so March–May can still be good for swimming despite the heat.

What is the weather in Thailand in February?

February is in the cool season. Expect clear skies, low humidity, and daytime temperatures around 28–33°C. Nights are cooler, especially in the north. It’s one of the driest months nationwide, ideal for sightseeing and beaches.

Is October a good time to visit Thailand?

October is the tail end of the rainy season. Rain is still frequent but often limited to afternoon showers. Temperatures are 26–32°C with high humidity. The west coast remains wet, but the east coast begins to dry out. Good for budget travel if you don’t mind occasional rain.

How humid is Thailand by month?

Humidity is lowest in the cool season (50–65% in December–February) and highest during the rainy season (75–90% from June–October). The hot season sees moderate humidity (60–75%) but feels oppressive because of the heat. Check the live forecast above for current conditions.
