In Chiang Rai and the Golden Triangle region, heavy rains will make trekking hard work; however the countryside is more green and lush, and the rivers and waterfalls are in full flow.
In terms of beaches, the islands of Koh Chang and Koh Kood are particularly wet in July. Further south, rough seas may be experienced off the west coast and the beaches of Phuket, Krabi and Khao Lak have a much higher chance of heavy downpours than the east coast beaches of Koh Samui, Khanom and Koh Pha Ngan, which are significantly drier and are still enjoying prolonged sunny spells. July is a particularly popular month for diving around Koh Tao.
