In reply to snipper: can you read a map & compass?
can you understand weather forecasts?
can you make rational decisions?
have you experience on other british mountains?
are you reasonably fit?
if you answer yes to all, then if the weather is good, i reckon you`ll be fine.
be safe & enjoy it.
ps, as this is ukc, you can expect a load of withering remarks, probably beginning in reply to my answer
