Northern Thailand is predominantly covered with mountains, hills, and forests. This mountainous region experiences three seasons: hot, rainy, and cold. The rains usually arrive between mid-May and mid-October, influenced by the southwest monsoon.

At the beginning and end of the rainy season, the showers are less intense, allowing for travel despite intermittent rain. Costs are generally lower, and the landscape becomes lush green after each shower. Just be sure to equip yourself with suitable clothing and footwear. Using effective mosquito repellent and wearing long clothing for protection is also essential.

During the peak rainy season in July, August, and September, it’s best to avoid traveling to higher mountainous regions. August is the rainiest month, with an average of 223.2 mm of rain spread over about 21 days. Heavy rainfall can cause landslides, making travel dangerous. Additionally, due to the mountainous and forested topography, the wet period attracts many insects, especially mosquitoes.
