Climate
Bhutan has a varied climate, due to its diverse topography, with the northern region of the country being colder than the south. The country experiences four main seasons: the cool winter season from December to February, the pre-monsoon season from March to May, the monsoon season from June to September, and the post-monsoon season from October to November.
The monsoon season is characterized by heavy rainfall, which can cause landslides and flooding in some areas. The best time to visit Bhutan depends on the regions you plan to visit and what you prefer in terms of weather.
Best time to visit
The best time to visit Bhutan is from October to December, during the post-monsoon season, when the skies are clear, the air is crisp, and the weather is mild. During this time, visitors can enjoy the country's natural beauty and explore its historical sites without the heat and humidity of the summer months.
If you want to experience the traditional Bhutanese festivals and events, then the months of September to December are the best time to visit. On the other hand, if you want to explore the country's natural beauty and go on treks, then the months of March to May would be the best time to visit, as the weather is mild and the landscape is lush green.
Keep in mind that the monsoon season of June to September can be unpredictable, and many of the country's outdoor attractions may be closed or have limited hours during this time. Visitors are advised to check the weather forecast and plan accordingly, as well as to take necessary precautions when travelling during the monsoon season.
