In reply to Euge: I went up to Coire Na Ciste on Ben Nevis on Sunday to have a look, but the turf wasn't frozen, the snow was soft with no base, and there was a lot of ice in cracks, so overall pretty poor conditions for climbing. Only one other team out, on Tower Ridge, but they bailed at the Little Tower due to slow progress.
The past two days have been mild, wet and very windy, but things are looking to slowly cool down over the next few days. My only slight concern is that the icing in the cracks is only going build with the gentle freeze/thaw cycles happening between 800 and 1000m, not great for mixed climbing but this will help the ice climbs form.
