Time To Trek In Nepal: Season-by-season

Autumn (mid-September to mid-December) and spring (March to May) are the best seasons to trek in Nepal. They bring stable weather, clear skies, comfortable temperatures and the sharpest mountain views of the year.

That does not make the rest of the year off-limits. Winter suits shorter, lower treks and sightseeing, and the summer monsoon is the ideal time for Nepal's rain-shadow regions such as Upper Mustang and Dolpo. Choosing the right season for the right route is the single biggest factor in how much you enjoy your trip.

This guide walks through each of Nepal's four trekking seasons: what the weather is really like, which treks and peaks suit it, and how the Nepal Trekking Trail team plans around it.

Autumn: mid-September to mid-December

Autumn is Nepal's number-one trekking season. The monsoon rains wash the dust from the air, leaving crisp blue skies and some of the clearest Himalayan panoramas you will ever see.

Weather and temperature

Autumn traditionally begins in mid-September as the monsoon retreats. In recent years, though, the rains have often lingered into early October, so early-season trekkers should expect a few showers in the first weeks.

Once the monsoon clears, expect mostly sunny days with little rain. Clouds lift away from the peaks and mornings are especially clear.

• Daytime: around 18–23°C at mid elevations
• Night: around 10–13°C at mid elevations
• High altitude: nights drop well below freezing above 4,000 m, especially from November

It is rarely too hot or too cold on the trail, which makes long walking days comfortable and enjoyable.

Festival season

Autumn is also Nepal's biggest festival season, which adds a cultural highlight to any trek.

• Dashain – Nepal's largest Hindu festival, celebrated with family gatherings, blessings and kites over the hills
• Tihar – the festival of lights, when homes glow with oil lamps and animals such as crows, dogs and cows are honoured
• Chhath – a sunrise and sunset devotion to the Sun God, celebrated beside rivers and ponds
• Tamu Lhosar – the Gurung New Year at the end of December, colourful in the Annapurna foothills

If you would like to celebrate with local families, let us know and we can build festival days into your itinerary.

Why we recommend autumn

Based on many years of guiding, the Nepal Trekking Trail team recommends mid-September to mid-December above all other periods for trekking, touring and peak climbing. The weather is the most reliable of the year, views are at their best, and trails and teahouses are fully open.

The one trade-off is popularity: classic routes such as Everest Base Camp and Annapurna Base Camp are busy in October and November. Book flights to Lukla and teahouses early, or choose a quieter route.

Spring: March to May

Spring is Nepal's second great trekking and mountaineering season, and for many travellers it is the most beautiful. The hills turn green, wildflowers bloom and the forests blaze red, pink and white with rhododendron, Nepal's national flower.

Weather and temperature

Spring follows straight after winter. The cold retreats to higher altitudes and temperatures rise steadily day by day. Most days are sunny with clear blue skies, especially in the mornings.

• Daytime: around 20–25°C at mid elevations
• Mornings and evenings: around 10–12°C
• Late spring: warmer and more humid, with occasional afternoon showers in the mid hills and fresh snow higher up

By late May the pre-monsoon build-up begins. Afternoon clouds become more common and haze can soften distant views, so March and April usually offer the clearest skies.

Why trek in spring

• Rhododendron forests in full bloom, especially on the Ghorepani Poon Hill, Langtang and Makalu routes
• Green landscapes as new crops and plants grow across the hillsides
• Peak climbing season – spring is the main window for many Himalayan expeditions, and Everest Base Camp is at its liveliest
• Longer, warmer days that make high passes more comfortable

For travellers who cannot come in autumn, spring is an equally rewarding time to experience the Himalaya.

Best treks, tours and peaks for autumn and spring

Both peak seasons open up almost every route in Nepal, from short hill walks to remote base camps and 6,000-metre summits.

Autumn and spring offer the most stable summit windows. Every climb includes acclimatisation days and an experienced climbing guide.

Winter: mid-December to early March

Winter is a good time for shorter, moderate treks and sightseeing, but not for long high-pass routes or peak climbing. Days are often bright and clear, yet temperatures drop sharply at altitude and heavy snowfall can block trails.

What to expect

Temperatures are lower than in autumn and spring, though not extreme at lower elevations. Kathmandu and Pokhara stay pleasant by day, while nights in the mountains are very cold.

The main risk is unpredictability. A heavy snowfall can close high passes such as Thorong La or Cho La for days, cut a trek short, or stop you completing the full journey. Some high-altitude teahouses also close for the season.

Our winter advice

The Nepal Trekking Trail team always tells winter travellers the same thing: come to Nepal, enjoy the quieter trails and sightseeing, but keep your trek short and moderate. Avoid planning long, high-pass adventures in these months.

Treks suited to winter

• Ghorepani Poon Hill Trek
• Mardi Himal Trek
• Langtang Valley Trek
• Everest Panorama View Trek
• Pikey Peak Trek
• Everest Base Camp Trek (with warm gear and flexible dates)
• Gokyo Lake Trek (with warm gear and flexible dates)
• Upper Mustang Trek (very cold but dry)
• Annapurna Circuit Trek (Thorong La may close after heavy snow)

A quality down jacket and a four-season sleeping bag are essential for any winter trek. We can arrange good-quality hire gear in Kathmandu.

Summer (monsoon): late June to September

Summer in Nepal is the monsoon season, and it is the least favourable time for most treks. Heavy rain makes trails muddy and slippery, triggers landslides, brings leeches to the forests, and often hides the mountains behind cloud. Domestic flights, especially to Lukla, are frequently delayed.

Where to trek in the monsoon

The monsoon is the perfect time for Nepal's rain-shadow regions. Sitting behind the main Himalayan range, they receive very little rainfall:

• Upper Mustang Trek
• Nar Phu Valley Trek
• Dolpo region treks
• Tibet: Kailash and Lake Manasarovar tour

Trekking safely in summer

Trekking elsewhere in summer is possible with precautions, but we do not generally recommend it. Your safety always comes first.

If you do trek in the monsoon, build spare days into your itinerary, carry good rain gear and leech socks, and travel with an experienced guide who can judge trail conditions day by day.

The reward is a Nepal few visitors see: hills and valleys alive with vibrant green, waterfalls in full flow, fresh air, and almost empty trails.

Frequently asked questions

What is the single best month to trek in Nepal?
October is generally the best month, with the most stable weather and the clearest views. November is a close second and slightly quieter.

Can beginners trek in Nepal? Yes. Short treks such as Ghorepani Poon Hill, Mardi Himal or the Everest Panorama View Trek suit first-time trekkers in any season except the monsoon.

Is it too cold to trek in winter? Not at lower and moderate altitudes. With a good down jacket and sleeping bag, winter treks are comfortable and the trails are quiet. High passes are best avoided.

Can I trek during the monsoon? Yes, in rain-shadow regions such as Upper Mustang, Nar Phu and Dolpo. Elsewhere, monsoon trekking is possible but we do not usually recommend it.
