Climate and Average Weather in Thailand

Thailand has a tropical climate and the weather varies each season. In the colder season (November - February) the average maximum temperatures fall between 28°C (82°F) and 33°C (91°F), while during the summer (March - May) you can count on 30°C (86°F) to 37°C (99°F). April is the warmest month.

May is the start of the rainy season on the west coast and it lasts until the end of October. Usually, the rain storms are short, but with very heavy downpours. September and October are on average the wettest months throughout the country.

The best time of year to visit the west coast is between November and April, while for the east coast we recommend between December and May.

In the cold season in the north of Thailand sometimes the temperature will fall under 10°C (50°F) in the evening. However during the day the temperature will rise to almost 30°C (86°F) again.

There is a possibility of encountering typhoons or cyclones in Thailand. Cyclones form in the period April to December over the Indian Ocean. But because they mainly move in western, northwestern and northern directions, they don’t tend to hit mainland Thailand. If they do happen to head your way, there’s a greater chance at the beginning and end of the cyclone season.
