Thailand in July: Weather & Where to Visit

By Chris QuanUpdated May. 24, 2021

July falls in the middle of Thailand’s rainy season. Rainfall tends to be on the increase during this time, with an average precipitation of 170 mm (6 in) in the major tourist cities and an average temperature of 29°C (84°F).

This doesn’t mean that your trip will be ruined by continuous downpours. Traveling during the rainy season is better than you might think. You can still visit inland areas and some islands that experience less rain during this season.

Bangkok and Central Thailand

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

Dark clouds bring sudden downpours, which is followed by sunny weather. This will make you feel humid and hot at times. Staying refreshed in indoor swimming pools and cold showers will help relieve any discomfort.

Northern Thailand

Northern Thailand experiences heavy rainfall during this time, but because of its mountainous terrain and inland location, it will be cooler than other regions in Thailand. The weather is mostly cloudy and drizzly. The average temperatures for Chiang Mai and Chiang Rai in this month are 27°C (80°F).

Southern Islands

Most of the southern islands will be affected by the monsoons in July, which bring heavy rains and turbulent waves. The average temperature in July ranges between 26°C (80°F) and 28°C (83°F). This weather will last until the end of October.

We recommend avoiding islands in the Andaman Sea and eastern islands in the Gulf of Thailand, such as Phuket, Krabi, Koh Lanta, and Koh Chang.

However, some islands experience fewer showers during this season and have good weather in July; these are Koh Samui, Koh Tao, and Kao Pha Ngan. You can still enjoy sunny days at the beach on these islands.

Why Visit Thailand in July

People usually avoid the rainy season when traveling because the constant rainfall can take a toll on your mood, make your uncomfortable, and attractions may be closed.

But Thailand in July experiences short bursts of rain that leave the air clearer and temperatures a bit lower. The weather in July is usually cloudy, overcast, or sunny with showers.

Sunny days are interrupted by heavy downpours lasting for one or two hours, after which the sun will shine through the clouds again. So, there is little chance that your trip will be ruined.

Moreover, you can enjoy some of the benefits of the rainy season, such as quiet beaches, less-crowded streets and attractions, and affordable prices.
