Not sure if the sun stays below Mt Ventoux at all when days are shorter? That may impact hotness/coldness...
How's the weather likely to be? Looking at going for two weeks late Nov to early Dec - it looks amazing (I have been for a day 20 years ago, but barely remember anything TBH) and some mates will likely be out there anyway, but given it will be a quickish hit I really don't want to be watching the rain. Not freezing my arse off would be nice too. The lack of ticks on UKC in Nov/Dec is making me nervous...
I cannot imagine that the nearby Dentelles of Montmirail are ever seeping or too cold. Not that I particularly like the climbing there
