Gokyo Cho La Pass Trek in August

The wet months are when the lakes of the Gokyo valley are at their fullest. The research mooring at the fourth lake had the water level rising from early July to the end of the record in early September. A visitor in August walks beside a lake that is still filling, under cloud.

Both Hindus and Buddhists hold the lakes sacred, and Wikipedia says about 500 Hindus take a holy bath there at Janai Purnima, usually in August. A trekker in the valley on that full moon shares it with pilgrims.

The pass is the same as in any month in its order of events: a steep climb on loose rock, a short glacier stretch, then the descent to Dzongla. Rain and cloud are the difference. Our tour notes call the Cho La risky during the monsoon, and August has the least margin for that.

August trekkers are few. The park's mid-July to mid-August window recorded 125 entries in 2024, and the mid-August to mid-September window 1,331. No count for August alone is quoted.

The Gokyo side is simpler than the main trail even in October, as our tour notes say, so ask which lodges are open before you book.

August flights leave from Kathmandu under our flight notice. The weather-service record puts 642 mm of rain at Lukla in August, the wettest month of the year, and HoneyGuide's 2020 article calls July and August the highest-risk window with one flight a day and about 22 rainy days. Those 22 days are a HoneyGuide average, not a measurement we hold.

If you go, put several spare days at the end, not the single day 18 of the day table.
