Frequently asked questions
Gai Jatra (the cow festival, mid-August — Bhadra month full-moon day) is a Newari mourning ritual unique to the Kathmandu Valley. Families who lost members in the past year parade with cow-painted wooden frames or decorated cows through the streets — the cow is believed to lead the deceased to the afterlife. The festival is also famous for satire and humor (the king traditionally allowed mocking commentary on this day, an old tradition continuing in modern Newari communities). Bhaktapur and Patan run the most-cited Gai Jatra celebrations. Pack: modest cotton, slip-on sandals, packable rain shell, sun hat, water bottle.
Mixed — August is peak monsoon: 23 rain days, humid, high-altitude trekking paused, mountain views obscured. But August brings festival season (Gai Jatra, Krishna Janmashtami, Teej), the Kathmandu Valley at maximum green, lower hotel rates than peak winter, fewer tourists. If you go: pack rubber sandals (skip leather), packable rain shell, modest cotton, DEET, ORS for hydration, travel insurance with medical evacuation. The post-monsoon September-November and pre-monsoon March-May are the most-cited Nepal seasons.
