In reply to Ramblin dave:
I've climbed at all the venues I've listed early rock climbing season as they are fairly fast drying, lowish altitude and south facing (being in the sun at this time of year not only dries the rock quicker but makes the whole thing much more pleasurable).
Aonach Mor East Face is probably the slowest drying venue I've listed although it's not too bad.
I'm not sure on current conditions but West coast the snow level looks fairly high on the web cams (>700 metres?) but Cairngorms look more wintery than many winters and to quite a low level!

generally the further west you go (especially on to the islands) the higher the snow level (but often the more of it!)
