The best time for the Annapurna Base Camp trek is October and November for mountain views, or March and April for rhododendron forests and spring scenery. Both windows offer stable weather, fully operational tea houses, and safe trail conditions.
But the honest answer is more nuanced than that. The “best” month depends on what you’re optimizing for views, solitude, cost, or specific scenery. This guide breaks down every month of the year so you can match the trek to your schedule, not the other way around.

Best Time for Annapurna Base Camp Trek
The Two Peak Seasons in Detail
Autumn: October and November
This is the gold standard for the ABC trek and the reason October is the single busiest trekking month in all of Nepal.
The monsoon exits Nepal in late September, leaving behind freshly washed skies and zero haze. From the first week of October through late November, you get the most consistent mountain visibility of the entire year. On a clear October morning at Poon Hill or Annapurna Base Camp, the views are simply unrepeatable Annapurna I, Annapurna South, Machhapuchhre, Dhaulagiri, and Gangapurna all visible simultaneously, razor-sharp against blue sky.
October is peak of peak. Every tea house on the route is operating at full capacity. The trail between Chhomrong and Deurali sees hundreds of trekkers per day. Accommodation in popular stops like Ghorepani and Chhomrong should be booked in advance. Daytime temperatures at base camp sit around 5°C–10°C, dropping to -5°C overnight. Lower on the route (Pokhara to Chhomrong) it’s comfortable hiking weather 15°C–22°C during the day.
November offers almost identical conditions with meaningfully fewer crowds and colder temperatures. By mid-November, daytime highs at Annapurna Base Camp drop to 0°C–5°C and nights fall to -8°C to -12°C. The trail above Machapuchare Base Camp may see early-season snow by late November. Pack accordingly your sleeping bag rating matters more in November than October.
Who autumn suits: First-time trekkers, anyone who prioritizes mountain views above all else, photographers, trekkers wanting the fullest tea house experience.
The trade-off: You will share the trail. If the idea of queuing for tea house space at Deurali bothers you, autumn is not your season.
Spring: March, April, and May
Spring is the second-best season and the clear favorite for trekkers who’ve already done the ABC in autumn and want a different experience.
The defining feature is the rhododendrons. Nepal’s national flower blooms across the entire lower section of the ABC route Ulleri to Ghorepani to Tadapani from late February through April. At peak bloom in late March and early April, the forest trail between Tikhedhunga and Ghorepani is extraordinary: a tunnel of red, pink, and white rhododendron at 2,000m to 3,000m elevation, with snow peaks visible through the canopy.
March sees the rhododendrons beginning to bloom at lower elevations and opening progressively higher through the month. Weather is mild and mostly stable, though pre-monsoon haze builds through the day and distant views are less crisp than autumn. Morning views are generally clearer than afternoons. Temperatures are comfortable warmer than autumn at equivalent altitudes.
April is the peak of rhododendron season and arguably the most beautiful month on the lower route. The trade-off is increasing haze and some afternoon cloud buildup as the pre-monsoon approaches. Views at Annapurna Base Camp are still reliable in the mornings but less guaranteed than October. Crowds are moderate busier than March but far quieter than October.
May is underrated. The rhododendrons are finishing at lower elevations but still blooming higher up. Pre-monsoon clouds are building and views can be patchy, but the trail is quieter than any other good-weather month. Temperatures are warmer sometimes uncomfortably so at lower elevations but comfortable at altitude. If you want the ABC trek experience without the crowds and can tolerate some view uncertainty, May is worth considering.
Who spring suits: Trekkers who want scenic lower-route forest trekking, photographers interested in flora as much as peaks, anyone who finds autumn crowds off-putting, returning trekkers wanting a different visual experience.
The trade-off: Morning views at ABC are good but less consistently spectacular than October. Pre-monsoon haze means some days the peaks stay hidden until late morning or not at all.
The Monsoon: June, July, August (Approach With Caution)
The monsoon arrives in Nepal from the Bay of Bengal in early June and dominates through mid-September. For the ABC trek specifically, this means:
- Daily rainfall of 10–30mm at lower elevations, heavier at altitude
- High landslide and flooding risk on the Chhomrong–Sinuwa section of the route, which runs through a narrow gorge prone to debris flows
- Cloud cover obscuring mountain views for the majority of each day
- Leeches on the lower trail sections (Tikhedhunga to Chhomrong) a genuine nuisance, not a danger, but worth knowing
- Many tea houses operating at reduced capacity or closed entirely in July–August above Bamboo
July and August are the months to avoid entirely unless you are an experienced mountain trekker who specifically wants the challenge, the solitude, and the lush green monsoon landscapes. Annapurna Base Camp receives snowfall even in July, and sudden weather changes in the sanctuary can trap trekkers.
June and September are transitional months. Early June still has reasonable weather before the monsoon fully establishes. Late September (from roughly the third week) sees the monsoon withdrawing and conditions improving rapidly some trekkers deliberately time September arrivals to catch the early-autumn window with fewer crowds than October.
Who monsoon trekking suits: Experienced trekkers seeking absolute solitude and the specific beauty of monsoon-green Nepal landscapes. Not recommended for first-timers, anyone with limited time, or those for whom mountain views are the primary motivation.
Winter: December, January, February
Winter trekking on the ABC route is underappreciated by Western trekkers and genuinely rewarding for those prepared for the cold.
December offers some of the clearest mountain views of the year. The post-monsoon atmosphere from autumn persists, and the lower trekker numbers mean you often have tea houses and viewpoints to yourself. The main consideration is temperature nights at Annapurna Base Camp drop to -15°C to -20°C in December, and the trail above Machapuchare Base Camp can be snow-covered and icy. A sleeping bag rated to -15°C is essential above Deurali. Traction devices (microspikes) are strongly recommended for the ABC–MBC section in December.
January is the coldest month. Temperatures at base camp regularly hit -20°C overnight. The upper sanctuary trail is frequently snow-covered. Some tea houses above Deurali reduce services or close temporarily during the coldest weeks. However, the mountain views on a clear January day are extraordinary arguably the sharpest of any month. Experienced trekkers with the right gear who want dramatic winter mountain photography find January uniquely rewarding.
February sees temperatures beginning to moderate. By late February the upper route is generally clear of serious snow, and the first rhododendrons begin opening at the lowest elevations. February is a sweet spot for trekkers who want winter solitude without the extreme January cold and who want to catch the very beginning of the spring bloom on the lower route.
Who winter suits: Experienced trekkers with proper cold-weather gear, photographers wanting dramatic winter mountain light, trekkers who prioritize solitude and are comfortable with cold. Not recommended for beginners or anyone without a quality sleeping bag and cold-weather layering system.

Practical Considerations by Season
Accommodation Booking
- October: Book Ghorepani, Chhomrong, and Deurali accommodation at least 2–3 weeks ahead through your agency or directly with tea houses
- All other months: Walk-in availability is generally fine
Cost Variation by Season
Peak season (October–November) doesn’t dramatically affect tea house prices, but flights to Pokhara and Kathmandu hotels cost more. Budget 15–20% more for accommodation and flights in October versus March or November.
Guide and Porter Availability
Licensed guides book up quickly for October. If you’re planning an October trek, arrange your guide at least 6–8 weeks in advance through a registered trekking agency.
Travel Insurance
Ensure your policy covers the specific months you’re trekking some policies have monsoon exclusions for high-altitude rescue. Helicopter evacuation coverage is essential regardless of season. [See our complete guide to travel insurance for the ABC trek.]
Frequently Asked Questions
What is the best month for the Annapurna Base Camp trek?
October is the single best month for mountain views and trail conditions. November is a close second with fewer crowds. March and April are the best spring months, particularly for rhododendron scenery.
Can you do the Annapurna Base Camp trek in December?
Yes, with the right gear. December offers excellent views and low crowds. You need a sleeping bag rated to -15°C, warm layers, and ideally microspikes for the section above Machapuchare Base Camp. Some tea houses above Deurali have reduced services in late December.
Is March or October better for the ABC trek?
October for mountain views clearer skies and more consistent visibility. March for scenery variety blooming rhododendrons, green forests, and mountain views that are good if not quite as sharp. If it’s your first time, October. If you’ve been before and want a different experience, March.
Can you trek Annapurna Base Camp in the monsoon?
Technically yes, but it’s not recommended for most trekkers. The Chhomrong–Sinuwa gorge section carries significant landslide risk in July and August. Mountain views are obscured most of the day. July and August are the months to avoid.
How cold is Annapurna Base Camp at night?
In October: -5°C to -8°C. In November: -8°C to -12°C. In December–January: -15°C to -20°C. In March–April: -2°C to -5°C. A sleeping bag rated to at least -10°C is recommended for October–November trekking.
Is November too cold for the Annapurna Base Camp trek?
No with the right gear, November is one of the best months. Pack a -10°C to -15°C sleeping bag, quality insulating layers, and warm gloves. The cold at altitude is manageable with proper preparation, and the rewards clear skies, fewer crowds, stunning light are significant.
When do rhododendrons bloom on the ABC trek route?
Rhododendrons bloom progressively from lower to higher elevations. At lower elevations (Tikhedhunga, Ulleri) blooming starts late February. The prime Ghorepani–Tadapani forest section (2,800m–3,200m) peaks in late March to mid-April. Above 3,500m, bloom extends into early May.
What is the least crowded time for the Annapurna Base Camp trek?
July and August have the fewest trekkers but for weather reasons, not by design. Among the good-weather windows, February, late September, and late November offer the best combination of decent conditions and low crowds.
