@Pedro.....the thing is with us Brits (particularly for motorcyclists) is our lives are determined by the weather. So we focus on it more than you.
You're guaranteed pretty decent conditions for most of the year......but if you're in Britain you're not even guaranteed decent conditions in the Summer.
So it's a case of grabbing what you can, then being laid up for indefinite periods. Unless you want to splash around in the pissing rain of course.
