The number everyone compares, Larkya La's 5,106m against Thorong La's 5,416m, is the wrong way to size up this trek.

April, October and November are prime season. March, May and September are good with caveats. February and December are shoulder season. January, June, July and August are the tough months. Every month below opens a full report: temperatures at real waypoints, trail and summit conditions, crowd levels, flights and what we advise.
Permits close. Weather windows narrow. The best Everest region teahouse beds fill by October, and spring season opens again in March. Our Kathmandu team is already booking for autumn. If you have been planning a trek, this is the window.
