Lower-valley daytime and night conditions
Machha Khola–Deng can be hot and humid at roughly 23–30°C by day and 14–19°C at night.
Samagaun and Samdo temperatures
Samagaun/Samdo may reach 6–14°C in daylight and fall to about −4 to 2°C overnight; wind still makes the pass feel wintry. 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
The crossing is commonly possible, but afternoon cloud, wet snow and individual pre-monsoon storms can reduce visibility or leave fresh accumulation.
Rainfall, cloud and visibility
Clearer mornings often give way to afternoon cloud, showers and occasional thunderstorms; mountain views become less consistent late in the month.
Daylight hours
Around 13½ hours, the longest useful daylight of the main spring trekking season.
Crowds and lodge pressure
Moderate early, usually easing as pre-monsoon moisture increases. Lodge pressure is lower than peak April or October.
Road reliability
Mostly usable, but the first heavy storms can trigger local slips and roughen the Machha Khola approach.
Exact packing adjustments
Add quick-drying lower-valley shirts, stronger rain protection, pack liner and insect repellent while retaining a −10°C sleeping bag, insulated jacket and gloves for the high route.
Compared with the month before and after
Warmer and greener than April but cloudier; June is substantially wetter with much less reliable roads and views.
