Spring Trekking March, April & May
What Is the Weather Like During Spring ABC Trek?
Annapurna Base Camp records 4°C–14°C daytime temperatures in spring. Night temperatures drop to -8°C in March and reach 0°C by May. Trails above 3,000m open from mid-March as snow melts. Trail conditions from Chhomrong to ABC stay walkable from March 10 onward in most years.
When Do Rhododendrons bloom on the Annapurna Base Camp Trail?
Rhododendrons bloom March–April at 1,800m–3,200m elevation. Peak bloom concentrates at three trail sections:
- Ghorepani (2,874m) densest concentration, peaks late March
- Tadapani (2,630m) mixed forest bloom, peaks early April
- Sinuwa (2,360m) lower-elevation bloom, peaks mid-March
April 10–25 delivers the densest flowering across all three zones simultaneously.
How Clear Are Mountain Views in Spring?
Spring 2025 recorded clear days averaging 18 out of 30 in April at ABC. Forest fires created haze below 2,500m on some days 5,130+ fires burned across Nepal in spring 2025. Above 3,000m, visibility remained unaffected. Views from ABC included Annapurna I (8,091m), Machhapuchhre (6,993m), and Hiunchuli (6,441m) on most mornings.
If you are a first-time Himalayan trekker planning for this window, you might find that the Annapurna Circuit Trek for Beginners offers a comparable but slightly more challenging alternative.
What Does Spring Trekking Cost?
Spring is one of the most popular trekking seasons in Nepal due to clear skies and pleasant weather. Trekking costs can vary depending on your style of travel, accommodation, and package choices. Here’s a quick overview of typical expenses:
- Teahouse per night: $10–$20
- Package tour (10–14 days): $700–$1,200
- Pokhara flight availability: High
- ACAP permit processing: 1–2 days
Who Should Trek Annapurna Base Camp in Spring?
Spring suits first-time trekkers, photographers targeting rhododendron bloom, and families. April delivers the most balanced combination of warm days, open trails, and mountain clarity. Photographers choose between spring and autumn: April produces bloom-and-mountain shots; October produces sharp summit views without flowers. For those assessing their capabilities, knowing what fitness level is required for Annapurna Base Camp will help ensure a successful journey.
Monsoon Trekking June, July & August
Is It Safe to Trek Annapurna Base Camp During Monsoon?
Annapurna Base Camp receives its heaviest rainfall July–August. Pokhara records up to 800mm of rain per month in this period. The Deurali–MBC trail section (3,230m–3,700m) carries the highest landslide risk. July and August record the most trail closures of the year. Trekkers with fixed return flights should not attempt this window. Given these risks, it is clear why is Annapurna so dangerous during the peak of the rainy season.
What Are the Trail and Leech Conditions in Monsoon?
Leeches appear on trails below 2,500m from June onward. Trails above Chhomrong (2,170m) stay passable but remain wet and slippery. Waterfalls peak June–August a draw for landscape photographers. Visibility above 3,500m clears on some mornings between monsoon rain bands.
Which Teahouses Stay Open During Monsoon?
Most teahouses from Jhinu Danda to Deurali stay open year-round. Teahouses at MBC (3,700m) and ABC (4,130m) reduce staff July–August but remain open. Meal menus narrow to 4–6 items. Hot showers become unreliable above Deurali.
What Does Monsoon Trekking Cost?
Trekking during the monsoon season in Nepal can be cheaper than peak seasons, but it comes with extra considerations like rain, flight cancellations, and additional accommodation days. Here’s a breakdown of typical expenses:
| Expense | Monsoon Cost |
| Teahouse per night | $5–$12 |
| Package tour (10–14 days) | $500–$800 |
| Pokhara flight risk | High cancellation rate |
| Extra accommodation days (buffer) | Budget $20–$30 extra |
Who Should Trek ABC During Monsoon?
Monsoon suits budget trekkers, adventure photographers, and trekkers with flexible return dates. Monsoon does not suit first-timers, solo trekkers without guide experience, or trekkers with fixed flight schedules.
Autumn Trekking September, October & November
Why Is October the Best Month for Annapurna Base Camp Trek?
October delivers 0mm rainfall, 50km+ mountain visibility, and stable 16°C daytime temperatures at ABC. Post-monsoon air carries less dust and haze than spring. Annapurna I (8,091m), Machhapuchhre (6,993m), and Hiunchuli (6,441m) appear sharp on 24–27 days of October on average. When you consider the Annapurna Base Camp trek vs Everest Base Camp trek, October is the prime window for both, though ABC remains a more accessible entry point for high-altitude adventure.
What Festivals Fall During Autumn Trekking Season?
- Dashain 2026: October 2–12
- Tihar 2026: October 20–24
Trekkers experience decorated teahouses and local feasts during Dashain. Trekking traffic drops 15–20% during Dashain as some Nepali staff travel home teahouse service may be slower above Deurali during October 3–9.
How Early Should You Book for Autumn ABC Trek?
Teahouses at MBC and ABC fill by 2pm during October 5–25 (peak window). Book accommodation at least 2 months ahead. Pokhara flights for October sell out by August. Walk-in above Deurali carries real risk of no beds October 8–20. If you are unsure about the timeline, it is worth asking when should I start planning an Annapurna trek to avoid missing out on peak dates.
What Does Autumn Trekking Cost?
Autumn is one of the most popular seasons for trekking in Nepal, thanks to clear skies, stable weather, and spectacular mountain views. However, it’s also the peak season, which can affect costs, accommodation availability, and permit processing times. Here’s an overview of typical expenses during an autumn trek:
| Expense | Autumn Cost |
| Teahouse per night | $15–$25 |
| Package tour (10–14 days) | $800–$1,400 |
| Pokhara flight availability | High (book early) |
| ACAP permit wait | Longer queues |
Before you head out, ensure you have reviewed the Annapurna Circuit Trekking Permits 2026 for any mandatory registration requirements.
Who Should Trek ABC in Autumn?
Autumn suits all trekker types. October is the single safest month for first-timers. Families with children perform best October 1–15 warm days, stable trail, all teahouses fully staffed. Many wonder where is the Annapurna region located in Nepal when they first start researching; its accessibility from Pokhara makes it an ideal autumn destination.
Winter Trekking December, January & February
How Cold Does Annapurna Base Camp Get in Winter?
Annapurna Base Camp records -12°C to -15°C average night temperatures in January. Extremes reach -20°C (-4°F). Daytime temperatures stay near 2°C. Trail ice forms above 3,000m from December onward.

Which Teahouses Close in Winter?
During the winter months of December and January, some teahouses along the Annapurna Base Camp (ABC) trek operate with limited staff or close entirely. Knowing which stops are open helps plan your daily itinerary and meals.
| Location | Status (Dec–Jan) |
| Sinuwa, Bamboo, Doban | Open year-round |
| MBC (3,700m) | 3 of 8 teahouses close |
| ABC (4,130m) | All open minimum staff |

How Climate Change Is Affecting Annapurna Base Camp Trek Timing in 2026
What 2025–2026 Data Reveal About the Annapurna Region
Recent data from the Annapurna region highlight changes in climate, natural hazards, and trekking conditions. Understanding these trends is essential for trekkers, local communities, and researchers monitoring environmental shifts in the Himalayas. Here’s a simplified snapshot of key findings:
- Rising Temperatures in Nepal: The country’s average temperature has increased by 0.056°C per decade, showing a gradual warming trend across the region.
- Extended Monsoon Season: In 2024, the monsoon lasted until the end of September, affecting trail conditions and river levels.
- Forest Fires in Spring 2025: Over 5,130 fires were reported, creating haze in areas below 2,500 meters, impacting both air quality and trekking visibility.
- October Snowfall: Snowfall above Deurali was reported in 2023 and 2024, influencing trail accessibility and acclimatization for trekkers.
- High-Risk Glacial Lakes: 21 glacial lakes in Nepal have been identified as high-risk for potential outbursts, posing threats to downstream communities and trails.
