May is an excellent month to trek before the monsoon arrives in June. However, trekkers should be prepared for slightly warmer and more humid conditions in lower elevations.

Weather & Temperature

June marks the beginning of the monsoon season in Nepal. The lower parts of the Annapurna Circuit receive frequent rainfall, making the trails muddy and slippery. However, the higher altitudes remain relatively dry with occasional rain showers. The skies are often cloudy, reducing the visibility of the mountains.

• Lower Elevations (1,000m – 2,500m): 18°C to 26°C (64°F to 79°F) during the day, 10°C to 15°C (50°F to 59°F) at night.
• Mid-Elevations (2,500m – 4,000m): 10°C to 18°C (50°F to 64°F) during the day, 3°C to 8°C (37°F to 46°F) at night.

Trekking Conditions & Safety

• Frequent rain in the lower regions, especially in the afternoons.
