May can be a challenging time to visit Thailand. While the weather remains relatively pleasant in the north of Thailand, with warm temperatures and occasional rain, the rest of the country can already hear the echoes of the coming monsoon season.
The southern and central parts of Thailand can be very hot and humid, with temperatures peaking at times, so if you're not a fan of extreme heat, it's worth considering visiting Thailand at a different time.
Despite the challenging weather in Thailand in May, this month can offer more budget travel options due to fewer tourists.

May signals the start of the rainy season in Thailand, but it's still hot. In Bangkok, daytime highs reach 94°F (34°C), and nighttime temperatures hover around 79°F (26°C). Chiang Mai cools slightly, with highs of 93°F (34°C) and lows of 73°F (23°C).
The south, including Phuket, Krabi and Samui, experiences more rain, with about 10 inches (250mm) of precipitation and temperatures between 77°F (25°C) and 90°F (32°C). The humidity levels rise significantly across the country, making it feel warmer than the actual temperature suggests.
Daily sunshine drops to around 6-7 hours in many areas. Despite the rain, May can still be a good time for cultural experiences and indoor activities, though beach days in the south might be interrupted by sudden showers.

May marks the start of the low season as temperatures stay high and the first rains of the monsoon season begin. Crowds thin significantly, and prices for accommodations drop, particularly in beach destinations like Krabi, Koh Phi Phi, and Koh Lanta. While rain is more frequent, it usually comes in short bursts, leaving plenty of sunny hours for exploring. It’s a great time to find deals and enjoy quieter beaches.
