The figures below are approximate Kathmandu averages. Pokhara is a little warmer and much wetter, and temperatures drop roughly 6°C for every 1,000 m you climb.

January: Cold, Clear and Quiet
One of the coldest months, especially above 3,000 m, but Kathmandu and Pokhara often have crisp, clear days with sharp mountain views. Heritage sites are uncrowded.
Go for: Kathmandu Valley temples, Pokhara's lakeside, Chitwan wildlife, short low-altitude hikes.
Watch out: Kathmandu mornings can be foggy, and the air quality is poor in winter. Check snow and nighttime temperatures before booking any high-altitude trek.
February: Late Winter, Early Spring
Still cold in the mountains, but the days begin to warm by the end of the month. Visitor numbers remain low, and Losar (Tibetan New Year) and Maha Shivaratri bring colour to Kathmandu, Boudhanath and Pashupatinath.
Go for: cultural sightseeing, scenic drives, Chitwan and Bardia, lower-altitude walks.
Watch out: High passes may still be snowbound.
March: Spring Trekking Begins
Trekking weather improves across Nepal. Rhododendrons start to bloom in the lower hills, and the popular routes begin to fill up.
Go for: Ghorepani Poon Hill, Langtang Valley, Annapurna Base Camp and early Everest-region treks.
Watch out: Mornings and nights stay cold at altitude. Layer up, and expect haze by afternoon.
April: Rhododendrons and Lively Trails
One of the best months for trekking. Rhododendron forests are at their peak across the hills; days are warm and Nepali New Year falls in mid-April.
Go for: Annapurna, Everest Base Camp, Langtang, and village walks combined with cultural sightseeing.
Watch out: Trails and lodges are busy. Book permits, guides and accommodation ahead.
May: Warm, Hazy and High-Altitude
The final pre-monsoon month. It is the main window for Everest-region expeditions, and higher rhododendron slopes are still in bloom. Haze, afternoon cloud and the occasional storm can reduce views.
Go for: high-altitude treks, Upper Mustang (including the Tiji festival, usually in May) and Buddha Jayanti in Lumbini.
Watch out: Lowlands become hot, so plan outdoor activity for early mornings. Upper Mustang can be very windy in the afternoons.
June: The Monsoon Arrives
Rain builds through the month. Hills turn green, but trails are muddy, and weather is changeable. Many travellers avoid the mountains, so prices and crowds drop.
Go for: museums, temples, food experiences, village stays, and a well-planned rain-shadow trek.
Watch out: Allow extra time for road journeys and domestic flights.
July: Wettest Month
Heavy rain, cloudy mountains and slippery trails. Landscapes are at their greenest, and the pace of travel is slow.
Go for: cultural sights between showers, countryside stays, Upper Mustang, Upper Dolpo or Nar Phu with a registered agency.
Watch out: Landslides can block highways. Check road status and keep your itinerary flexible.
August: Monsoon Continues
Heavy rain continues, but the countryside is vibrant, and festivals such as Gai Jatra and Teej start to appear on the calendar.
Go for: photography of green terraces, cultural travel, rain-shadow treks.
Watch out: Build buffer days around flights and road transfers.
September: The Monsoon Fades
Rain eases through the month, and the air starts to clear. Early September is still wet, but late September can be excellent and quieter than October.
Go for: cultural tours around Kathmandu and Pokhara, and trekking from late in the month if conditions allow. Indra Jatra in Kathmandu usually falls in September.
Watch out: Check recent weather before committing to a mountain view itinerary.
October: Peak Season
Often the single best month to visit Nepal. Skies are clear, trails are dry, and the mountain views are superb. Dashain, Nepal's biggest festival, usually falls in late September or October.
Go for: Everest Base Camp, Annapurna Circuit and Annapurna Base Camp, safaris and scenic road trips.
Watch out: This is the busiest month. Book flights, lodges and permits early, and expect that some transport is full during Dashain as Nepalis travel home.
November: Clear Skies, Cooling Air
Still excellent. The air is crisp, views remain outstanding, and crowds ease as the month goes on. Tihar, the festival of lights, usually falls in October or early November.
Go for: trekking, mountain photography, Kathmandu Valley heritage sites, and village walks.
Watch out: Nights get cold quickly at altitude. Bring warm layers for early-morning viewpoints.
December: Quiet Holidays
Cold in the mountains, but sunny and pleasant at lower altitudes. Visitor numbers drop after the autumn peak, although Christmas and New Year bring a smaller wave of holiday travellers.
Go for: Kathmandu, Pokhara, Chitwan and low-altitude hikes.
Watch out: Check snowfall, temperatures and high-pass conditions before confirming a winter trek.
