In reply to Adam Moroz:
Fiend seems to think that Gogarth is the place to be over the winter months, not some godforsaken grit crag.
Whether this is cause enough for you to go there, or elsewhere, is your choice.
I've climbed there in November and February, and as long as it's dry in the run-up, and the route is carefully chosen to stick to open slabs rather than seeping cracks, it can be a damn sight warmer and more pleasant than a lot of places in N Wales or anywhere else in the UK at that time.
