Hat Yai experiences a tropical climate with two distinct seasons. The weather in the city is usually humid and hot.
Dry Season (January-April): Summers are hot with an average temperature of 30°C.
Wet Season (May-December): The wet season mostly has rainstorms and monsoons and the average daily is around 25°C.
Sometimes, the last two months in the year are regarded as the third season (winter). The best time to visit Hat Yai is October through December. However, it is not a bad idea to include the trip in your vacation planners during the monsoons as rain lasts only for a couple of hours and an umbrella would usually suffice.
