Nepal Weather Guide

Nepal’s temps are said to drop 6 degrees Celsius for every 1,000 metres gained in altitude. The north has the most extreme conditions, including severe winters, and the south has more tropical summers and milder winters. Kathmandu’s climate is relatively comfortable all year round.

Season and Clothing

Summer: June to August

Summer, or the monsoon season, is the least popular time to visit Nepal because of the wet and hot conditions across much of the country. If you like these temperatures, try a jungle safari in the south. Towards the end of August, you might see Janai Purnima and Gai Jatra, colourful Hindu processions featuring cows and people with bovine-style headgear to celebrate the cow transporting souls to the afterlife.

Autumn: September to November

Autumn is high season in Nepal with comfortable weather and clear skies great for exploring city sites as well as trekking. The 9-day Hindi Daisan festival in late September and early October sees everyone stay home from school and work, the skies filled with kites and marketplaces full with livestock to be sacrificed on the night of Kai Ratri. These autumn months are also the most popular time to do the 250-kilometre Annapurna Circuit with great weather and clear skies.

Winter: December to February

While the days can be sunny and comfortable, the winter nights can be a shock. Winter is at its most severe in December and January in Nepal. If you’re trekking, it is recommended to stick to the lower elevations where conditions are safer. This time of year offers perfect clear conditions to get up early and watch the sun rise over the Himalayas in nearby places such as Nagarkot on the rim of Kathmandu Valley, so set your alarm!

Spring: March to May

Another popular tourist season, spring is ideal for trekking and exploring Nepal thanks to comfortable weather and flowers such as rhododendrons in full bloom. Holi, the Hindu festival of colour, celebrates the end of winter and the start of spring where everyone plays and chases one another with coloured powders and coloured water. Don't miss the World Heritage Listed site of Chitwan National Park to see rare and endangered animals such as the Bengal tiger and one-horned rhino.
