By June the summer monsoon brings frequent rain to much of Bhutan, reducing visibility in the mountains and making high passes slippery. Many trekking routes become more challenging and some rural roads may be affected by landslides. Lowland and southern areas are hotter and wetter.

Average temperature across Bhutan in June.
Samtse, Sarpang, Phuentsholing
July is the wettest month here: rain can fall in long, heavy spells and rivers in Sarpang and Samtse can rise quickly, sometimes forcing road closures. Mosquito numbers climb; accommodation without good screens will be uncomfortable. Border towns are busy with local trade but not ideal for sightseeing-if you are transiting through to the highlands, plan buffer days for weather-related transport slowdowns.
Paro, Thimphu, Haa
June sees the onset of the southwest monsoon influence: showers become more frequent, especially in the late afternoon, and humidity rises though the valleys rarely see the torrential cloudbursts of the plains. Lower slopes can be misty and trails turn slippery, so expect muddy approach paths to monasteries and fewer clear panoramas. Travel plans that include Chele La or high ridge walks should include contingency days for rain and cloud.
Punakha, Wangdue, Trongsa, Bumthang
June introduces increasing moisture from the monsoon, with more frequent showers and cloud in Punakha and eastern-facing slopes; Bumthang often stays drier but sees occasional downpours. Fields in Punakha and Wangdue turn bright green and rivers rise, so riverbank walks can be muddy. Travelers should allow flexibility in itineraries-landslips on feeder roads are possible after heavy rains-though lower-altitude cultural sites remain accessible.
Trashigang, Mongar, Trashiyangtse
June brings heavier rains to the eastern hills as the southwest monsoon establishes itself; steep gullies can funnel sudden downpours, and landslides on secondary roads are a common travel disruptor. River levels rise quickly, making some short, rural crossings difficult or temporarily impassable. This is not the ideal month for long overland exploration of remote eastern routes, though cultural visits in bigger towns remain possible.
Gasa, Laya, Lunana, high passes
June is a transitional and risky month in the alpine zone because the monsoon begins to push northwards: accumulated snow becomes unstable and high passes may close with sudden storms. Lower highland camps remain accessible early in the month but carry waterproof and insulating gear, and be prepared for itinerary changes. Trekking groups often prefer to be off the highest ridges before the monsoon’s full force builds.
There are no major festivals or events in Bhutan during June to be aware of.
