Browse the full Manaslu Circuit library →August requires separate planning for the warm Budhi Gandaki corridor and the exposed upper route. Persistent winter snow is unlikely, yet fresh high snow, rain, fog and unstable moraine can still block a safe crossing window.
Lower-valley daytime and night conditions
Lower valleys remain around 24–30°C by day and 18–22°C at night with very high humidity.
Samagaun and Samdo temperatures
Samagaun/Samdo generally plans around 9–16°C by day and 2–6°C overnight, but prolonged cloud suppresses daytime warmth. These are broad planning ranges rather than a forecast; aspect, cloud, wind and individual weather systems can move temperatures outside them.
Larkya La snow tendency
Persistent winter snow is unlikely, yet fresh high snow, rain, fog and unstable moraine can still block a safe crossing window.
Rainfall, cloud and visibility
Frequent rain and cloud continue; short clear breaks are possible but should not be treated as a dependable sightseeing pattern.
Daylight hours
Roughly 13 hours by late month, with usable light shortened by cloud and afternoon rain.
Crowds and lodge pressure
Very low. High lodges may be closed or minimally staffed, and a quiet trail provides little passing traffic if help is needed.
Road reliability
Cumulative monsoon damage can be severe even when one day is dry. Expect uncertain roadheads, transfers and long waits around repairs.
Exact packing adjustments
Keep July-level waterproofing, dry bags, leech protection and spare socks; add sandals only for lodge use, never as a substitute on muddy or landslide terrain.
Compared with the month before and after
Similar rain to July but often with more accumulated road damage; September usually begins a gradual improvement while retaining mud and landslide risk.
