Figures marked provisional are seed data and still need verification. Source and last-checked date sit under each cited value.

Altitude weather delta

High 4,650 m minus low 1,722 m is 2,928 m of relief on this record. A standard tropospheric lapse of 6.5 °C per 1,000 m implies about 19 °C cooler at the high point than the valley, all else equal.

That is a model (International Standard Atmosphere environmental lapse), not a forecast and not a trail-closure. Wind, snow, and storms stay in Hazards.
