Weather in Kathmandu in June

Shoulder season. June is shoulder season in Kathmandu — cheaper, quieter, and a genuine gamble. You should expect rain on 22 days of the month, which is more days wet than dry.

June ranks 12 of 12 — near the bottom of Kathmandu's year. November is the month that works, and the swing between the two is 44 points, which is a different holiday rather than a slightly better one.

Rain on 22 of the month's 30 days, 6 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Pack for 29.1 °C days and 20.4 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 11 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest June day reached 35.4 °C and the coldest night fell to 16.6 °C, and the wettest single day dropped 55 mm — roughly 32% of the month's rain in one day.

June is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest June on record still delivered 326 mm against 72 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 170 mm average is a reasonable planning figure, not a promise.

Wind is light at 6.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 66%.

How June sits in the year

Temperatures hold steady either side: 29.8 °C in May, 29.1 here, 26.4 in July. Nothing about the timing within the month matters much. Rain is the thing that moves: July brings 5 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in June

June is at or near the longest days of Kathmandu's year: 13.9 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

Despite being inland, the year stays fairly even: 23.1 °C between the year's warmest afternoons and coldest nights. At 1317 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

June in Kathmandu versus nearby

If Kathmandu is one option among several, the nearby comparison is worth making. Bharatpur is the weaker option in June — 8.3 °C warmer, 1 day less rain. Pokhara is the weaker option in June — 2.9 °C warmer, 2 days less rain.

So: June is a compromise. November is 44 points better and is what Kathmandu is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
