The Annapurna Circuit Trek remains one of Nepal’s most iconic long-distance Himalayan journeys. But choosing the best time to trek Annapurna Circuit can significantly influence your overall experience — from mountain visibility to trail traffic and weather conditions.

This complete 2026/27 season guide explains Annapurna peak season, trekking weather in Nepal, seasonal crowd levels, and practical planning advice so you can confidently select the right departure window.

Understanding Nepal Trekking Seasons

Nepal experiences four primary trekking seasons. Each season creates a distinct atmosphere along the Annapurna Circuit — from vibrant rhododendron forests in spring to snow-dusted landscapes in winter.

• Spring (March–May): Stable temperatures and blooming hillsides
• Monsoon (June–August): Rainfall and lush landscapes
• Autumn (September–November): Crystal-clear mountain views
• Winter (December–February): Cold but peaceful trails

Annapurna Circuit in Spring (March–May)

Spring is one of the most popular choices for trekkers wondering about the best month for Annapurna Circuit. Days are comfortably warm at lower elevations, and the forests burst into color with rhododendron blooms.

• Average Day Temperature: 10°C–20°C
• Thorong La Pass Temperature: -6°C to -10°C
• Crowd Level: Moderate to High

Advantages: Excellent photography conditions, stable weather, scenic landscapes.

Considerations: Slight haze possible in late May.

Annapurna Circuit in Autumn (September–November)

Autumn is widely regarded as the Annapurna peak season. Post-monsoon air clarity delivers exceptional Himalayan views, making this period ideal for both first-time trekkers and experienced hikers.

• Average Day Temperature: 12°C–18°C
• Thorong La Pass Temperature: -5°C to -8°C
• Crowd Level: High

October typically provides the most consistent visibility, while November offers slightly quieter trails with cooler mornings.

Annapurna Circuit in Winter (December–February)

Winter trekking offers solitude and dramatic snow-covered scenery. However, Thorong La Pass weather can become challenging, especially after heavy snowfall.

• Day Temperature: 5°C–12°C
• High Pass Temperature: Down to -15°C
• Crowd Level: Low

Winter is best suited for experienced trekkers prepared for cold conditions.

Annapurna Circuit in Monsoon (June–August)

Monsoon season brings rainfall, particularly at lower elevations. While this period sees fewer trekkers and lower costs, trail conditions may include mud and occasional landslides.

• Day Temperature: 18°C–25°C
• Crowd Level: Very Low
• Budget Advantage: Yes

For those seeking drier alternatives during monsoon, Upper Mustang (rain-shadow region) is worth considering.

Seasonal Traffic & Planning for 2026/27

During peak months (October and April), demand for guides, permits, and teahouse accommodation increases significantly. Early booking — ideally 2–3 months in advance — is strongly recommended for Autumn 2026 departures.

Transport between Kathmandu, Pokhara, and trekking start points also becomes busier during these months.
