Thailand: Weather & when to go: July

July Overview

July marks another transitional period in Thailand, when temperatures finally start breaking from the 30s. Creeping down into the high 20s, the rains get stronger and longer lasting, which extend all the way into August.

The north moves into one of its wettest months of the year in July, which proves to make trekking very difficult, if not impossible in some parts. Despite the wet conditions, the rains create for much more lush conditions which prove to be beautiful during this time of the year. This is also a great time to see waterfalls and rushing rivers at their best. Similar weather patterns creep all the way down the country to the Bangkok region, which is also experiencing high rains at this time.

The southern regions are split between the rains, with Koh Chang, Koh Kood, Krabi, Phuket and Khao Lak all experiencing heavy rainfall. On the other side of the peninsula, however, Koh Samui, Koh Phangan and Koh Tao still enjoy relatively dry conditions, offering an oasis of sun and dry weather to beach-going travellers. Again, July marks an excellent time for diving in the waters surrounding Koh Tao.
