Phuket 23 30 267

In Bangkok and Central Thailand: The average temperature is about 29°C (85°F). Due to the monsoon winds, the weather can change rapidly even within the span of a day.

In northern Thailand, including Chiang Mai: The north experiences moderate rainfall during July, but because of its mountainous terrain and inland location, it is cooler than other regions of Thailand.

The southern islands: The west of the Thai peninsula is particularly affected by the monsoon in July, which brings heavy rains and turbulent waves.

However, some southern islands (those on the east coast) experience fewer showers during this season and have good weather (only moderate rainfall) in July; these include Koh Samui, Koh Tao, and Kao Pha Ngan. You can still enjoy sunny days at the beach on these islands.

Crowding and Costs in July

Few people choose July to travel to Thailand because of its heat and rain. Discounted rates can often be seen in many branded hotels and restaurants. The tourist sites and beaches are generally quiet and empty, which makes it a good time to go to relax, though you may need to retreat inside when afternoon/evening downpours come.
