Winter trekking is still possible on Poon Hill, which sits at just 3,210 metres-above-sea-level. The trail remains dry and firm below 2,500m and views of the snow-capped peaks are stunning.

Towards the end of January, the annual grass cut takes place in Chitwan, dramatically improving wildlife viewing including one-horned rhinos while endangered gharial crocodiles can be seen in great numbers on canoeing safaris as they enjoy the winter sun.

This is the month for safaris in Nepal with dwindling water sources, which leads to congregating rhinos and more likely tiger sightings in Bardia, against the crimson background of blooming Flame of the Forest trees.

Losar (Tibetan New Year) occurs in early February, marked by traditional masked dances and monastery rituals, while the deeply spiritual Maha Shivaratri takes place around mid-February.

The pilgrimage to base camps begins in earnest – the sun is shining, rhododendrons are blooming and the atmosphere is electric.

March is a top-tier time for wildlife viewing, from tracking Bengal tigers on the prowl for a mate in Bardia National Park to spotting sunbathing red pandas in eastern Nepal.

As the monsoon approaches, the crowds begin to thin while trekking conditions remain good for those willing to handle occasional afternoon showers.

Around mid-June, the monsoon arrives in Nepal, cutting tourist numbers in half and transforming the landscapes into a sea of green. The change in Kathmandu’s air quality is staggering, but road conditions can make travel tricky.

Thanks to its location in the Annapuran rain shadow, Upper Mustang receives a fraction of the rainfall. Days are pleasant, skies are clear and trails are lush and beautiful.

The rains also bring about Ropain (Rice Planting Festival) across Nepal, where women plant rice seedlings amidst a joyful community atmosphere. And visitors are very welcome to kick off their shoes and join in!

Tourist numbers are at an all-time low, leaving historic sights and streets fairly empty. However, you need to prepare for possible schedule changes due to road closures or flight delays.

Nepali locals celebrate the August full moon in the medieval walled city of Lo Manthang, when riders in traditional dress race dazzlingly decorated horses through the streets.

Hardcore birders may choose to brave the elements in search of monsoon ‘specials’ like cuckoos, minivets and more.

As the monsoon rains really start to decrease towards the end of the month, visitors can witness one of Nepal’s most unique festivals: Gai Jatra in Kathmandu’s Durbar Square and Bhaktapur Durbar Square host the most impressive celebrations.

Planning a visit in late September will likely reward you with clear skies and trails (all major trekking routes re-open) at a fraction of the peak season prices.

Dashain celebrations take place in mid-October, a time when the entire country reunites, but many shops and restaurants close on the main day (10th day of festival) – so plan accordingly.

Birding reaches an absolute zenith with a full complement of migratory species and dazzling native birds. In fact, this is considered by many to be the finest time for birdwatching on the Indian Subcontinent.

With fewer tourists than October, while the air clarity and trail conditions remain fabulous, this is an ideal time for trekking in Nepal.

For the adventurous, white water rafting is outstanding (although pretty chilly towards the end of November) and stable thermals promise superb paragliding.

On the wildlife side of things, tiger sightings are reliably good and the autumn window for tracking red panda is in its final stretch.

December is cold, especially the higher you go. However, the visibility is astounding so why not head to the Nagarkot View Tower for a 180-degree panorama of all 8 Himalayan ranges?

Morning fog in Chitwan and Bardia can be a challenge, but once it clears, you’ll be in for a memorable all-day safari with a high chance of rhino sightings.

If you long for those high-altitude views (but not spending too long in the winter temperatures), make the most of lower tourist numbers with a helicopter flight to Everest Base Camp.
