In terms of weather, July in Thailand hardly differs from the previous month of June. Temperatures drop slightly throughout Thailand in July and rainfall increases with short daily showers likely to become more prolonged. The west coast beaches have a much higher chance of heavy downpours than the east coast beaches that are significantly drier and sunnier.

The average relative humidity of 83% is perceived as uncomfortable. The average temperature is around 28°C. The Gulf Coast and offshore islands are likely the driest areas of Thailand in July. The southeastern islands, especially Koh Samui, Koh Phangan and Koh Tao, are therefore relatively good travel destinations in July.

Details about the weather in July

Bangkok and Central Thailand

July brings a slight increase in precipitation to Bangkok, in the vicinity of Ayutthaya and Central Thailand with between 15 and 20 rainy days a month. In some places, the continental provinces offer caution against flash floods. The temperatures are essentially the same as in June, which are around 32-33°C. It is recommended to visit the surroundings of Kanchanaburi or other national parks, which have enough water and lush nature at this time.

Eastern Thailand

In July, in Eastern Thailand, especially on the island of Koh Chang and the surrounding islands, torrential rains occur almost every day. The heavy rains can increase the risk of erosion and landslides. However, there are lots of water in waterfalls and beautiful jungles. After rain, the air is cooler and cleaner. The sea in this region is also warmed up to 30°C, storms with strong winds often occur. The temperatures are between 24°C and 31°C, and the sun will hardly be able to prevail. With bad weather, July is not a good time to visit this part of Thailand. For a drier vacation, it is better to plan a trip to Pattaya.

Northern Thailand

The southwest monsoon brings a long-awaited coolness to the north of Thailand. On average, the daytime air temperature does not exceed 30°C and at night it can drop to 18°C.

July is more wet in the northern provinces of Thailand like Chiang Mai. More frequent and very heavy showers can bring local short floods. While the surrounding nature comes to life during this period, trekking will be more challenging at this time as it becomes muddy and difficult. There will be even more rain in the border provinces of the north.

Northeast Thailand - Isan

In Isan, the weather in July is basically as in June. Rain falls every other day. The extreme northeast is covered with very heavy rain showers, so those new to hiking should be careful. You should prepare for 20 rainy days and an uncomfortable warm and humid atmosphere. Average temperatures are 24°C at night and 31°C during the day.

Southern Thailand - East Coast

The best weather in all of Thailand is still here. The eastern part of the south is not much different from June, except for a few more showers. Despite the fact that the wet monsoon reigns over the whole territory of Thailand, the rainfall on the coast of the Gulf of Thailand is slightly lower than in the west with only 8 rainy days in a month.

The northern part of the east coast such as Prachuap Khiri Khan, Hua Hin and Phetchaburi will be significantly drier than the popular province of Surat Thani and its islands of Koh Samui, Koh Phangan and Koh Tao. However, even if it rains, there will still be plenty of sun and nice weather so a beach holiday during the month might still be possible. Average daily temperatures are around 29-32°C. The water temperature at the beaches is 29°C.

Southern Thailand - West Coast

In July, the southwestern destinations of the country such the islands of Koh Lanta, Koh Phi Phi and Phuket, Khao Lak, Krabi has plenty of rainfall and the sea is rough with high waves. It is particularly wet in Ranong, while it rains less in Phuket, Trang and Satun. The islands in the Gulf of Thailand is certainly a better choice at this time as some of the islands can be difficult to reach due to sudden heavy storms. The air temperature reaches 30°C during the day and 26°C at night. The waters of the Andaman Sea are warmed up to 29°C. It should be noted that ferry connections to the islands is reduced due to the low season. Some tourist facilities may remain closed during the rainy season.
