Thailand: Weather & when to go: September

September Overview

Similar to August, September in Thailand is another of the wettest months to visit. Tourist numbers are at a seasonal low and great deals for low season can be found throughout the country. Rain falls heavily across the country and temperatures stay on a steady decline, generally sitting around the mid to high 20s. With peak humidity hanging heavy in the air, this is a big month for storms across the country.

For those still hoping to squeeze in a few beach days, southern Thailand’s offerings start to decrease. The rain-soaked destinations of Krabi and Phuket remain wet and the once go-to options of Koh Samui and Koh Phangan now move into their wet season. The resort towns of Hua Hin and Cha Am are the last places in the country to stay dry, but sun is never a guarantee during this time.

On a more positive note, while the Khao Sok area is entirely saturated in rain, September actually marks one of the best months to visit for wildlife spotting. The rains have turned the landscapes into vibrant green escapes, proving ideal for a range of the park’s exotic wildlife. While it’s necessary to bring appropriate rain gear, this is a great time to visit for those who are hoping to see some beautiful wildlife.
