Nepal Kathmandu Weather in June — Climate Guide
June in Kathmandu is low
June is low for Kathmandu.
June marks the arrival of the monsoon, usually around mid-month — warm, humid days near 28°C, nights around 19°C, and heavy, increasing rainfall (about 240mm). The rain often comes in intense bursts, frequently in the afternoon and evening, with clearer spells between.
This is firmly low season: prices drop and the city is quiet, but the mountains are usually hidden behind cloud, so it's a poor time for mountain flights or high-altitude views, and trails get muddy and leech-prone. On the plus side, the rains wash the air clean — June through the monsoon has the year's best air quality.

Kathmandu in June — Full Picture
June marks the arrival of the monsoon, usually around mid-month — warm, humid days near 28°C, nights around 19°C, and heavy, increasing rainfall (about 240mm). The rain often comes in intense bursts, frequently in the afternoon and evening, with clearer spells between.
This is firmly low season: prices drop and the city is quiet, but the mountains are usually hidden behind cloud, so it's a poor time for mountain flights or high-altitude views, and trails get muddy and leech-prone. On the plus side, the rains wash the air clean — June through the monsoon has the year's best air quality.
The landscape turns lush and green, and the valley's temples and squares look atmospheric in the rain (with fewer tourists). Indoor-friendly plans — museums, the Patan Museum, Newari dining, monastery visits at Boudha — pair well with the showers.
Pack quick-dry clothes, a sturdy umbrella, a rain jacket, and waterproof footwear, and build flexibility into travel plans, as heavy rain can cause delays and occasional landslides on mountain roads.
What to Wear & What to Pack
Monsoon begins (mid-June). Warm and humid, afternoons around 28°C, nights near 19°C, with heavy rain and high humidity. Light, quick-dry clothing, a rain jacket, an umbrella, and waterproof shoes. The cleaner-air, low-season, but wet time of year.
