Best time to visit Kathmandu: weather, crowds and events by month

Go in October or November for clear skies, dry days and the best mountain views from the valley rim; March and April are the second-best window but haze often hides the Himalaya. Skip June to early September, when monsoon rain falls most afternoons. Book around Dashain and Tihar, when transport fills.

Kathmandu month by month

Kathmandu sits at about 1,400 m in a bowl-shaped valley, so its weather is milder than the trekking trails but dirtier than the hills. Autumn brings the clearest air of the year; spring is warm but hazy; the monsoon soaks the valley almost every afternoon.

Use the table as a filter: pick the month, then check what it means for crowds, prices and what you can actually see.

Crowds, prices and when to book

October and November are the peak: trekking groups pass through Kathmandu, hotel rates in Thamel and Patan rise, and popular rooftop restaurants fill at sunset. Book accommodation and any domestic flight two to three months ahead for these months.

The quietest stretch is June to August, when rain keeps most visitors away and room rates drop. January and February are also cheap and calm, with cold nights but clear daytime sightseeing. March and April sit in between: busy with spring trekkers, but easier to book than autumn.

Two festival periods distort everything. Dashain, roughly mid-to-late October in 2026, and Tihar about a week later, send Nepalis home to their families: long-distance buses and domestic flights sell out days ahead, and many shops and offices close for the main days. If your dates overlap, lock in transport before anything else.

  • Book autumn hotels and domestic flights 2–3 months ahead.
  • For Dashain and Tihar, book buses and flights first, then hotels.
  • Monsoon months are cheapest but plan indoor days: museums, Durbar Squares, cafés.
  • Winter mornings can be foggy; schedule mountain-view drives for late morning.

What the weather means for your plans

Clear-sky months (October–November, plus February) are when the Himalaya shows from Nagarkot, Chandragiri and the valley rim. In spring the mountains are often lost in haze, so do not build a trip around a single viewpoint.

Monsoon rain rarely falls all day, but it falls often enough to flood streets and delay domestic flights. Valley roads to Bhaktapur and Patan are usually fine; hill roads and Lukla flights are not. Winter is dry and stable, but cold at night, and high passes close with snow.

Air quality is worst in the dry winter and pre-monsoon months, when dust and smoke settle in the valley. If you are sensitive, plan shorter outdoor blocks and use the clearer afternoons.

What it costs by season

Prices below are 2026 estimates for a mid-range double room in Kathmandu, and they swing more by season than by day of week.

What it costs by season
SeasonMid-range double roomNotes
Oct–Nov (peak)USD 40–90Book early; rates spike around Dashain and Tihar
Mar–Apr (spring)USD 30–70Busy but less tight than autumn
Dec–Feb (winter)USD 20–50Cold rooms cost less; check heating
Jun–Aug (monsoon)USD 15–40Cheapest; expect damp and fewer services

Estimates only; hostel beds and luxury hotels sit well outside these bands.

Practical tips

Layer for the valley: sunny 20 °C afternoons and near-freezing nights happen in the same week in winter. A dust mask or scarf helps in spring. Domestic flights and long-distance buses are the first things to sell out at festival time, so book those before hotels.

If your dates are fixed in the monsoon, keep a wet-weather plan: the Durbar Squares at Kathmandu, Patan and Bhaktapur, the garden at the Garden of Dreams, and museum afternoons all work in rain.

  • Carry cash for festival days, when ATMs and shops may be shut.
  • Buy a local SIM or eSIM on arrival for bus and flight updates.
  • Check the festival calendar before fixing dates in October or November.
  • Allow a buffer day before any domestic flight in monsoon season.

Questions people ask

When is the best time to visit Kathmandu?

October and November: dry, clear and the only months when the Himalaya is reliably visible from the valley rim. March and April are second best, but haze often hides the mountains. Avoid June to early September, the monsoon.

When is Kathmandu least crowded?

June to August, during the monsoon, and January to February, when cold nights keep visitor numbers down. October, November and April are the busiest, and Dashain and Tihar in October–November fill buses and flights.

What is the weather like in Kathmandu by month?

Dec–Feb: clear days, nights near 0 °C. Mar–Apr: warm, hazy, some late showers. May: hot and dusty. Jun–Sep: rain most afternoons. Oct–Nov: clear, dry, cool nights. Exact temperatures vary by year.

Is the monsoon a bad time to visit Kathmandu?

It is the cheapest and quietest season, and the city itself still works: Durbar Squares, museums and cafés. But rain falls most afternoons, valley roads flood, and domestic flights and hill treks are unreliable.

Should I avoid Dashain and Tihar?

Not necessarily, but expect full buses and flights, closed shops on the main days and higher prices. Book transport first. The processions and lights are a reason to come if you plan around the closures.
