Thailand in May | Things to Do, Budget & Insider Tips

Thailand is a island paradise that has beautiful places, and friendly people, and nice cultures and so it is a year-round travel destination. But for the travelers who prefer a quieter atmosphere and love the rainy season, visiting Thailand in May offers a different experience. This guide will cover things such as what to expect, what to see, and what to do to help make the most out of your trip to Thailand in May.

Weather in Thailand in May: What to Expect

May, the start of the Thai southwest monsoon, puts an end to the long period of dry weather and finally brings the first meaningful fall of the year. Humidity rises quickly, reaching as high as 75% to 85%, which can make it feel even hotter between about 25°C and 34°C..

It does not rain evenly throughout the country. The Gulf of Thailand coast, where popular spots include Koh Samui and Hua Hin, stays relatively dry through the first half of the month, while the Andaman coast, dominated by places like Phuket and Krabi, starts to see more rain showers moving into mid-May.

Sea temperatures are around 30°C, perfect for swimming, diving, and boating in between the showers. Sunshine is still averaging around seven hours a day, so mornings continue to be your best chance to get out for some adventures.
