Monthly weather averages & travel planning

Updated: March 2026
March is a good time to visit Kathmandu (6/10). With 11 daily sunshine hours and only 10 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 3rd sunniest of the year in Kathmandu. Culture-focused travellers and those who prefer lighter crowds will find March a practical choice, with prices running lower than peak April without sacrificing all the good weather. April offers a similar profile at lower hotel rates if dates are flexible. The main practical note: Kathmandu's popular sites are busiest between 10am and 3pm regardless of season. Arriving at opening time or after 4pm makes a significant difference to the experience. Planning tips: accommodation is generally available without long lead times, and flight prices are typically lower than peak season. Flexible travellers will find the best deals by booking 2-4 weeks ahead. Mid-week arrivals consistently unlock lower hotel rates than weekend check-ins.
Visiting Kathmandu in March means warm daytime temperatures peaking at 22°C. Factor in 10 potential rainy days and 70% average humidity when planning your daily activities.

The 11°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset. Humidity averages 70%, which is comfortable for most visitors. On warmer days, lighter fabrics help with the mild stickiness in the afternoon. UV index averages 6 this month, classed as moderate. Sunscreen is a sensible precaution for extended outdoor time, particularly at midday. Winds are calm at an average 9 km/h, so wind-chill is not a factor in planning your clothing.

Packing for Kathmandu in March means dressing for 22°C days and 11°C evenings. A light cotton tee with a casual overshirt works well at 22°C, the overshirt doubles as a layer for air-conditioned venues. Evenings drop 11°C to around 11°C, a notable shift that catches underprepared visitors off guard. Pack a dedicated evening layer. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. A compact foldable umbrella weighs almost nothing and earns its keep across 10 potential rainy days. For temple and religious site visits, carry a lightweight scarf or sarong to cover shoulders and knees, required at most major sites across the region.
Local tip: Temple and religious site visits require covered shoulders and knees in most of Kathmandu's heritage areas. A lightweight scarf or sarong weighs almost nothing and solves the problem instantly.
March has no major festivals or public holidays in Kathmandu, which is one of its practical advantages for independent travellers. Attractions run at lower capacity than during peak event periods, queues are shorter, and accommodation is easier to find without needing to book many months in advance. Local restaurants, markets, and transport operate at a relaxed pace, making this an ideal time for visitors who prefer a more authentic, unhurried experience of everyday city life rather than large crowds drawn in by a single major headline event.
Based on 22°C average highs and 10 rainy days
March marks the transition into warmer conditions in Kathmandu, as the sun angle climbs and day length extends. Temperatures averaging 22°C by day and 11°C overnight reflect a city shaking off winter: the morning air still carries a cool edge, but afternoons are noticeably warmer than even four weeks prior. At 28 degrees north latitude, spring is one of the most dynamic periods in the annual cycle, with weekly temperature changes that can be larger than the month-to-month shifts of summer. This volatility is part of the appeal: Kathmandu in March has a freshness and energy that peak-summer heat tends to mute. The warmth is sufficient for outdoor dining and long walking days.

Sunshine Hours
The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.
UV Index
A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate, wear sunscreen. UV 6-7: High, hat and SPF 30+ essential. UV 8-10: Very High, limit midday exposure. UV 11+: Extreme, seek shade between 10am-4pm.
Rain Days
A rain day is counted when precipitation exceeds 0.1mm. This threshold captures even light drizzle. Unlike total rainfall in mm, rain days tells you how often you might need an umbrella, which is useful for planning outdoor activities.
