Official source: Department of Hydrology and Meteorology (DHM)
Nepal's weather and flood forecasts are issued by the Department of Hydrology and Meteorology (DHM), through its Meteorological Forecasting Division (MFD). This page links directly to their official resources rather than trying to reproduce their forecast data, since that's the only way to guarantee you're seeing accurate, current information — a live forecast quoted secondhand can go stale or wrong.
Open the national weather forecast → Open flood monitoring →Emergency weather & flood hotline
DHM operates a toll-free number for urgent weather and flood information: 1155 — press 1 for weather forecasting, press 2 for flood early warning. This is a verified, official number, useful especially during monsoon season (roughly June to September) when flash floods and landslides are a real risk in many parts of the country.
Nepal's seasons at a glance
General climate patterns — always check the official forecast above for current conditions, since Nepal's terrain creates huge local variation between the Terai lowlands, the hills, and the high Himalaya.
Cold and dry, especially in the hills and mountains. Kathmandu Valley sees cool mornings and clear afternoons; the high Himalaya gets heavy snow. Good visibility makes this a popular season for trekking at lower altitudes.
Warming temperatures, occasional pre-monsoon thunderstorms, and Nepal's famous rhododendron blooms in the hills. One of the two main trekking seasons thanks to relatively stable weather.
Heavy rainfall nationwide, especially in the hills and Terai. Flood and landslide risk is highest during this period — the 1155 hotline above is most relevant during these months. Trekking in rain-shadow areas like Upper Mustang and Dolpo is still possible.
Widely considered Nepal's best weather: clear skies, stable temperatures, and excellent mountain visibility right after the monsoon clears. Coincides with Dashain and Tihar, and is the peak trekking and tourism season.
About This Weather Resource Page
This page deliberately doesn't try to embed a live weather forecast. Nepal's official weather authority, the Department of Hydrology and Meteorology (DHM), blocks automated access to its site for data scraping and doesn't provide a public API for third-party sites to pull live data from — so rather than show secondhand data that could be stale or wrong, this page links you straight to DHM's own current forecast.
What's here instead
Direct links to the official national forecast and flood monitoring systems, the verified 1155 emergency weather/flood hotline, and a season-by-season guide to Nepal's climate that stays useful and accurate regardless of what today's specific forecast says.
Frequently Asked Questions
Why doesn't this page show a live forecast directly?
Nepal's official weather site (dhm.gov.np) blocks automated access for data scraping and doesn't offer a public API for third-party sites to pull live data into a page like this. Rather than show potentially stale or inaccurate secondhand data, this page links directly to the official source so you always see DHM's current, authoritative forecast.
What is the 1155 number for?
It's DHM's toll-free hotline for weather and flood information — press 1 for weather forecasting, press 2 for flood early warning. It's most actively used during monsoon season (roughly June to September) when flood and landslide risk is highest.
When is the best time to visit or trek in Nepal?
Autumn (Ashwin–Mangsir, roughly October–November) is generally considered the best season for clear skies and mountain visibility, followed by spring (Chaitra–Jestha, March–May). Always check the official DHM forecast above before travel, especially during monsoon season.
