In reply to Mr. Lee:
Thought you'd get more responses Lee. I've not climbed in the Khumbu, but I guess you know Oct-Nov is meant to give cold clear weather below 7000m, firmer neve, less deep snow (unlike April) and all that. Valleys clear of snow but more snow/avos above 7500m etc.
But from reports last year it was a bit too dry, a bit too cold and windy and some 6000er routes were a bit bare. Fwiw, this year's monsoon has hit early and heavy, but that's no guarantee it will finish early.
The eastern end (Kanch area?) is slightly more south of course so the post-monsoon season should run a little longer before winter, in theory. I've also heard of more snowfall here but I can't see evidence of that and up on the border, from any pics I've seen, it's really quite dry. Noticeably that the bulk of Slovenian new routes over the years, here and in the Khumbu, are in late October, almost on November. Kanch also has a long walk in and apparently starting low down in the mid-Sept monsoon is leachy and unpleasant.
