Weather in Kathmandu

Weather - Kathmandu, Nepal

Kathmandu's weather is dominated by a clear dry season and a strong summer monsoon. Winters (December–February) are cool and mostly dry with crisp mornings, spring (March–May) brings rapidly warming days and stronger sunshine, while the summer monsoon (June–September) delivers heavy rain and high humidity. Autumn (October–November) is widely regarded as the best time to visit for trekking and sightseeing thanks to dry skies and excellent visibility.

Weather - Kathmandu, January

January is one of the coolest and driest months: daytime highs around 17 °C and chilly nights near 5 °C. Skies are often clear, making it a good month for city sightseeing, sunrise views and photography—pack a warm jacket for early mornings and evenings.

Weather - Kathmandu, February

February warms up slightly (around 19 °C / 7 °C) with low precipitation. It's a pleasant shoulder month for travel: fewer tourists than peak season but improving temperatures—ideal for short treks and cultural tours.

Weather - Kathmandu, March

March marks spring arrival with daytime averages near 23 °C and mild nights (~11 °C). Sunshine increases and flowers begin to bloom, making it a great time for sightseeing and lower-elevation trekking before the pre-monsoon humidity builds.

Weather - Kathmandu, April

April is warm (around 27 °C / 14 °C) with abundant sunshine—but also the start of more frequent showers and very strong UV (bring sun protection). It's an attractive month for visitors who prefer warm, mostly dry days and excellent mountain views between sporadic rain.

Weather - Kathmandu, May

May stays warm (highs ~27–29 °C) but rainfall rises sharply as pre-monsoon and cloud build-up begin. Expect more humid conditions and increasing chances of heavy showers—consider this when planning outdoor activities and treks at lower elevations.

Weather - Kathmandu, June

June ushers in the monsoon: daytime temperatures remain around 27–29 °C but rain becomes frequent and often heavy. High humidity and reduced sunshine make it the wettest time to visit; travel plans should allow flexibility for downpours.

Weather - Kathmandu, July

July is typically the rainiest month, with very high monthly precipitation and many overcast days. While temperatures are moderate (mid‑20s °C), persistent rain limits trekking and sightseeing; indoor cultural experiences and short local excursions are more realistic.

Weather - Kathmandu, August

August remains in the monsoon core: heavy rain, high humidity and limited sunshine. Road conditions and visibility in the hills can be affected—this month suits travelers prepared for wet weather rather than ambitious outdoor plans.

Weather - Kathmandu, September

September sees the monsoon gradually retreat with rainfall falling compared to mid-summer but still significant. Temperatures stay warm (mid-20s °C) and late-month clear spells begin to appear—good for those catching the tail end of the wet season.

Weather - Kathmandu, October

October is a favorite month for travelers: skies clear after the monsoon, humidity drops and daytime highs (around 25–26 °C) are comfortable. Visibility for mountain panoramas is excellent, making it ideal for trekking and sightseeing.

Weather - Kathmandu, November

November is very dry and pleasant with mild days (~22 °C) and cool nights (~11 °C). Low precipitation and clear air create superb conditions for high-altitude treks and cultural exploration—one of the best months to visit Kathmandu.

Weather - Kathmandu, December

December returns to cool, mostly dry weather with daytime highs near 18 °C and chilly nights around 7 °C. Days are generally sunny and good for sightseeing—pack warm clothing for the mornings and evenings.
