Nepal Kathmandu Weather in August — Climate Guide
August in Kathmandu is low
August is low for Kathmandu.
August stays firmly in the monsoon — warm, very humid days near 28°C, nights around 20°C, and heavy rain (about 330mm), though typically a touch less than July. Daily downpours continue, with clearer breaks between storms.
It remains low season with low prices, small crowds, and the year's clean, rain-washed air, but the mountains are still mostly hidden behind cloud, so it's a weak month for mountain flights and high views, and trails stay muddy.

Kathmandu in August — Full Picture
August stays firmly in the monsoon — warm, very humid days near 28°C, nights around 20°C, and heavy rain (about 330mm), though typically a touch less than July. Daily downpours continue, with clearer breaks between storms.
It remains low season with low prices, small crowds, and the year's clean, rain-washed air, but the mountains are still mostly hidden behind cloud, so it's a weak month for mountain flights and high views, and trails stay muddy.
Where August shines is festivals. Janai Purnima (the sacred-thread festival) and the lively Gai Jatra (cow festival, with costumes, satire, and processions, especially in Bhaktapur and Patan) fall this month, along with Krishna Janmashtami, celebrated at Patan's Krishna Mandir. It's a culturally rich, atmospheric time despite the rain.
Plan around the weather with indoor-friendly sightseeing and flexible travel, and pack proper rain gear. The green valley and festival energy make it rewarding for travelers who don't mind getting wet.
What to Wear & What to Pack
Late monsoon, still very wet and humid. Afternoons around 28°C, nights near 20°C. Light, quick-dry clothing, a rain jacket, an umbrella, and waterproof shoes. Clean air, low prices, but mountains still mostly hidden.
