Nepal doesn’t have a single “best” season — it has four distinctly different ones, each pulling a different kind of traveler. I’ve spoken with countless guides and trekkers over the years, and the answer always comes back to the same question: what do you actually want to do while you’re there? The month you choose shapes everything — whether you’re watching rhododendrons burn pink across a hillside, sharing a teahouse with Sherpa families during Dashain, or hiking into a rain-shadow desert while the rest of Nepal drowns in monsoon.
The Two Peak Seasons: Spring and Autumn
Spring (March–May): Rhododendrons, Altitude, and Clear Mornings
Spring is the season that fills Lukla’s tiny airport first. March through May is when the rhododendron forests on the approach to Ghorepani Poon Hill turn deep crimson and pink — a detail that photos rarely capture because the scale is genuinely overwhelming. At lower elevations around Pokhara (800m), daytime temperatures sit around 22–26°C in March, climbing to 28–32°C by May. Up at Namche Bazaar (3,440m), you’re looking at 5–10°C during the day with overnight lows dipping below freezing.
The Everest Base Camp route sees its highest traffic in April and May. These two months account for the bulk of summit attempts on Everest — the jet stream moves north in May, opening a window of calmer upper-atmosphere winds. Trekking permits for Sagarmatha National Park run NPR 3,000 per person (roughly $22 USD). Add a TIMS card at NPR 2,000 ($15 USD) and you’ve covered the basic paperwork. Get them sorted in Kathmandu before you fly to Lukla — the Lukla office is not where you want to discover a documentation problem.
One practical note: tea houses from Namche up to Gorak Shep fill fast in April. Book ahead if you can, or be ready to share a room with a stranger. The dal bhat, for the record, is almost always good.
Autumn (September–November): The Gold Standard
Ask most veteran trekkers when to go and they’ll say October without hesitation. The monsoon clears out in mid-September, and what it leaves behind is some of the sharpest mountain visibility you’ll find all year. On a clear October morning from Poon Hill (3,210m), you can see the entire Annapurna massif — Dhaulagiri (8,167m) to the west, Machhapuchhre’s unmistakable fish-tail silhouette to the east, and a thin slice of Annapurna I’s south face catching the first light.
Temperatures in autumn are comfortable across the trekking belt. Pokhara sits at 18–24°C. On the Annapurna Circuit, Manang (3,500m) runs around 5–12°C during the day. Above 5,000m, expect sub-zero nights regardless of the month — pack accordingly and don’t rely on teahouse blankets alone.
October also falls during Dashain and Tihar, Nepal’s two biggest festivals. Dashain (usually mid-October, date varies by lunar calendar) is the country’s equivalent of a national holiday — families reunite, goats are sacrificed, new clothes are bought, and kites fill the skies over Kathmandu. Tihar follows about two weeks later; Kathmandu’s Thamel district and the old city around Durbar Square get strung with oil lamps and marigolds. Budget a few extra days in the capital — banks close, some shops shut, and domestic flight schedules get chaotic.
The downside is cost and crowds. A teahouse room that costs NPR 300–500 ($2–4) in the off-season can climb to NPR 800–1,200 ($6–9) in October. Budget trekkers often find November more agreeable — crowds thin after the festivals, prices settle, and the views stay sharp well into the month. Snow starts accumulating above 4,500m by late November but leaves the main EBC and Annapurna trails fully accessible.
Monsoon Season (June–August): The Case for Going Anyway
Monsoon gets a bad reputation, and in some ways it earns it. From June through August, heavy rain sweeps in from the Bay of Bengal. Landslides close roads between Pokhara and Mustang, trails in Sindhupalchok wash out, and the Prithvi Highway gets interrupted more than once every season. If your plan involves a standard southern-approach trekking route, June through August is genuinely difficult.
But here’s what most itineraries miss: the rain shadow areas north of the Himalayas stay dry. Upper Mustang — the walled city of Lo Manthang at 3,840m — sits behind the Annapurna and Dhaulagiri ranges. June and July there are sunny and windy, not wet. It’s actually the preferred time for restricted-area trekking in Upper Mustang, which requires a special permit currently priced at $500 USD for the first 10 days ($50 per day after that). The landscape is stark, the Tibetan-influenced architecture is extraordinary, and in peak monsoon you’ll share the trail with a handful of trekkers rather than a hundred. Dolpo’s high plateau behaves similarly — dry and austere when the south is flooded.
For travelers who don’t want high-altitude trekking, monsoon is jungle season in Chitwan. Royal Chitwan National Park fills with water and greenery, and wildlife sightings — one-horned rhinos, gharial crocodiles, Bengal tigers if you’re patient — can be excellent. Rafting on the Trishuli River is another option, though flow levels make some rapids significantly more serious in these months.
One honest warning: leeches. They’re active on jungle and lower-altitude trails from June through August. Not dangerous but persistent. Gaiters and a small packet of salt solve the problem quickly.
Winter (December–February): Quiet, Cold, and Underrated
December through February is the shoulder season that serious budget trekkers have quietly figured out. The crowds are gone. Tea houses are cheap. The lodges on the Annapurna Base Camp trail — which can feel like a crowded train station in October — become quiet enough that you’ll actually have a real conversation with your hosts about their lives and how the seasons have been shifting over the last decade.
The trade-off is cold. Thorong La pass on the Annapurna Circuit (5,416m) is crossable in winter but requires an early start — often 3 AM or earlier — to avoid afternoon winds. Snowfall can close the pass entirely for days at a time in January. Trekkers who attempt Thorong La in winter should carry crampons and microspikes, and be genuinely comfortable with cold-weather conditions even if they’re staying in teahouses.
Lower altitude destinations are more forgiving. Pokhara in January sits around 10–15°C during the day, dipping to 3–5°C at night. The Poon Hill short trek, topping out at 3,210m, is manageable in winter without specialized gear as long as you have proper sleeping layers. Rooms in Ghorepani cost NPR 200–400 per night in winter — a fraction of peak-season prices.
Kathmandu’s cultural sites shine in winter simply because there are fewer tourists. Pashupatinath, Boudhanath, and Swayambhunath are better experienced when you’re not elbowing through four guided groups at once. The Magar and Tamang new year celebrations also fall in February, mostly observed in villages west and north of the capital — the kind of thing you happen into if you’re in the right place and not in a rush.
Month-by-Month Breakdown
January and February
The quietest months on most trails. Room prices are at their lowest, and you’ll have Poon Hill almost to yourself at sunrise. February starts to warm slightly; Losar (Tibetan New Year) is celebrated in Sherpa and Tamang communities around Namche Bazaar and villages north of Kathmandu. Wildlife in Chitwan is good — dry season begins, animals concentrate near water sources.
March and April
Spring trekking season opens. Rhododendrons begin blooming at 2,000–3,000m in March and move upward through April. Temperatures are rising but still comfortable for trekking. April is peak EBC season — book accommodation weeks in advance. Poon Hill is crowded but spectacular, with forests around Ghorepani at full bloom.
May
Hot in Kathmandu (30°C and above). The Everest summit window opens in May. Upper trails above 4,000m are still excellent. A good month for the Annapurna Circuit before the monsoon arrives. Expect fully booked lodges on the EBC route and competitive prices.
June, July, and August
Full monsoon on standard routes. Upper Mustang and Dolpo restricted-area trekking is excellent and largely crowd-free. Jungle tourism in Chitwan and Bardia National Park picks up. The Janai Purnima festival in August sends thousands of Hindu and Buddhist pilgrims to Gosainkunda lake (4,380m) — remarkable to witness if you time it right, though the trail to the lake is intensely crowded for exactly one day.
September
Monsoon fades, usually clearing by mid-month. The trails are empty and prices are off-peak. September is one of the most underrated months for trekking — views sharpen daily as the rain clears, and you’ll find far fewer people than in October while conditions are nearly as good.
October
The classic month. Best overall visibility. Dashain festival in the first half, Tihar in the second. Maximum crowds and maximum prices on popular routes. Still worth it — the conditions are simply outstanding, and the festive energy in Kathmandu is something you won’t find at any other time of year.
November
Excellent trekking with declining crowds and prices. Snow starts accumulating above 4,500m by late November. A smart month for experienced trekkers who want good conditions without October’s congestion. Teahouse prices drop noticeably after the first week.
December
Winter sets in. Quiet, cold, and significantly cheaper. Fine for low-altitude and cultural trips. Pokhara’s lakeside is pleasant at midday. A good month for Chitwan if you’ve missed the main season windows.
Kathmandu Is Worth More Than a Transit Day
People sometimes treat Kathmandu as a transit hub — fly in, pick up permits, fly out. That’s a mistake. The city has a density of history and religious life that takes real time to absorb. The Durbar Squares in Kathmandu, Patan, and Bhaktapur are each different enough to justify a half-day each. The 2015 earthquake damaged significant portions of the Kathmandu and Bhaktapur complexes; reconstruction is ongoing and the scale of the loss is still visible in the scaffolding and covered foundations. That’s not a reason to skip it — it’s a reason to go now, while the rebuilding is happening and the history is tangible in a way it won’t be once restoration is complete.
Budget for accommodation in Thamel or the quieter Paknajol area: NPR 600–1,500 ($4.50–11) per night for a basic room, NPR 3,000–8,000 ($22–60) for something with reliable hot water, heating in winter, and a rooftop view of the city.
A Note from Nepal Trail Guide
We built this site because Nepal rewards the people who arrive prepared. The difference between a frustrating trip and a genuinely life-changing one often comes down to timing — knowing that Thorong La is crossable in November but you need crampons, that October means peak prices and pre-booking is essential, that Upper Mustang in July is one of the most underrated experiences available to a trekker anywhere in Asia.
The information on Nepal Trail Guide comes from real seasons, real conditions, and conversations with actual guides and lodge owners in Manang, Namche Bazaar, Jomsom, and Lo Manthang. Seasons shift, permit costs change, and trails get rerouted — if something here is out of date or you have a correction from the trail, let us know. We update regularly, because Nepal itself never stops changing.
