When to Go to Thailand: Seasons and the Difference Between the Seas

Thailand welcomes tourists all year round, but the weather depends greatly on the season and the region. Let us go through the three main periods and the difference between the seas.

Cool season: roughly November - February

• Weather: less heat and rain
• Pros: comfortable for walking around cities and temples, good weather at most resorts
• Cons: highest demand: more tourists, and prices for accommodation and tickets are usually higher

Hot season: roughly March - May

• Weather: very hot and humid, especially in the daytime
• Pros: fewer tourists than in winter, well suited to a beach holiday
• Cons: the heat is tiring in cities, so plan walks for the morning and evening

Rainy season: roughly June - October

• Weather: frequent tropical downpours, more often in the second half of the day
• Pros: green landscapes, fewer people, often lower prices
• Cons: on some islands the sea can be rough, and some tours are canceled

Two Seas, Two Schedules

In the west, on the Andaman Sea (Phuket, Krabi), the rainy period usually falls roughly in May - October. In the east, in the Gulf of Thailand (Samui), rains often come later, closer to the end of the year. So in the same month it may be dry on one coast and rainy on the other.

Important: the weather changes from year to year, and entry conditions and prices even more so. Before the trip, check a fresh forecast and verify current rules on official websites.

How to Choose

• Want to walk around cities and temples - choose the cool season
• Need a beach and fewer people - the hot season, but mind the heat
• Value greenery and budget - the rainy season
• Heading to the islands - first check which coast it is

Bottom Line

There is no perfect month for the whole country, only a good choice for the goals of your trip. Pick a region, check the forecast, and the trip will be more comfortable.
