By August, the Indian monsoons that drench southern and western parts of Bhutan are beginning to weaken in intensity, but waterproof apparel is still highly recommended for any intrepid travellers planning a trip at this time of year. You’re going to experience humid weather, with sun and mountain views alike obscured by cloud for much of the day.
Expect heavy rains in August in Bhutan, with the onset of autumn still a few weeks away. Most of the rainfall lands in the southern and western regions, including major visitor destinations such as Thimphu and Paro, but at this point in the summer it is usually a lot more manageable. Journeying up into the mountains, the views from the high passes continue to be largely obscured by low-hanging cloud, but you do get the occasional lucky glimpse of the Himalayan peaks. Beyond Punakha, the roads can be damaged by the rain, leading to delays, and trekking is a soggy old business. Because Bhutan is characterised by steep mountains and deep valleys, with tropical forests in the centre, the temperatures across the country can vary wildly. In August, Bumthang averages a mild 23°C during the day, while further west in Punakha, it can reach almost 30°C.
We encourage more time than is necessary - not too much but certainly not too little - to give Bhutan all the time it needs to reach into your soul.
