I dont recognise the institution of the "UK" since we are not united in any way, we all, Scots, Welsh, Irish, English, disagree over everything! I only use the word cos im lazy and cant be bothered explaining on F.B and other forums why Scotland is NOT part of England to to foreigners or non europeans. Truth is there is no UK.
Anyway, SCOTLAND has pretty dire weather really most of the time. Its 50/50 if its going to be dry or wet each day, normally freezing from Sept/Oct - March/April and we normally get our summer sun quota sometime between May-Sept. I have to carry wet gear every day unless its the height of "summer".
Oh and when i say sun, that doesnt mean like real proper sun like what everyone else seems to get, no, our "sun" seems to be a tad shy and runs off as soon as you look at it.
Saying that we do normally get good snowboarding weather and have plenty of good ski resorts up north so it aint all bad.
