Monthly weather averages & travel planning

Asia › 🇳🇵 Nepal › Kathmandu
Updated: March 2026
October is a fair time to visit Kathmandu (5/10). With 10 daily sunshine hours and only 15 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 6th sunniest of the year in Kathmandu. Culture-focused travellers and those who prefer lighter crowds will find October a practical choice, with prices running lower than peak April without sacrificing all the good weather. September offers a similar profile at lower hotel rates if dates are flexible. Watch out for prolonged rain stretches: with 15 wet days, a fully outdoor itinerary is risky. Build in museum days and covered market visits as contingency. 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 October means warm daytime temperatures peaking at 23°C. Factor in 15 potential rainy days and 70% average humidity when planning your daily activities.

The 8°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 6 km/h, so wind-chill is not a factor in planning your clothing. In Fahrenheit: 73°F average high, 59°F overnight low. Data sourced from Open-Meteo ERA5 climate reanalysis (1991–2020 normals).
Packing for Kathmandu in October means dressing for 23°C days and 15°C evenings. A light cotton tee with a casual overshirt works well at 23°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 15°C, a modest 8°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. With 15 rain days expected, a compact travel umbrella is worth the bag space. A waterproof jacket is better than an umbrella if you plan full-day outdoor routes. 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.
October 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 23°C average highs and 15 rainy days
October brings the first meaningful shift toward cooler conditions in Kathmandu, as the sun angle drops and day length shortens. Temperatures averaging 23°C by day and 15°C overnight are still comfortable by most standards, but the trend is clearly downward. At 28 degrees north latitude, autumn light has a particular quality: lower in the sky and warmer in tone, it gives the city a photogenic quality quite different from summer. Conditions remain excellent for outdoor activity, and crowds thin compared to the summer peak. Climate data: Open-Meteo ERA5 (1991–2020).
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.
Humidity
Relative humidity as a percentage. Below 40%: Dry, skin and throat may feel parched. 40-60%: Comfortable, ideal for most people. 60-80%: Sticky, light breathable fabrics recommended. Above 80%: Muggy, heat feels more intense; quick-dry clothing is essential.
