The weather on the Manaslu trek is quite unpredictable as the highest point on the trek is located at an altitude above 5,000m (16,000ft.). The weather varies differently during different seasons like any other trekking regions in Nepal. Be prepared for the quickly changing weather, humidity, rain, and strong winds during the trek, sometimes all of these on the same day. Temperatures during the spring season range from -6 to 12°C (21° to 54°F) while during the fall the temperatures are between 8° to 12°C (46° to 54°F).
