I would say that we're normally wet, windy and cold but currently the south of England is in a drought with below average rainfall for the last 14 months, some hosepipe bans already in place. Not exactly sunny but it seems as if the norm is fairly dry at the moment
Ignoring the built up areas the vegetaion is quite green although very few areas that you would consider as wilderness. If you've ever been to south Tasmania, the countryside is similar.
Rocky areas in Wales, North West England and Scotland. Best bet is too look up some images, quite a few in the BCUK galleries which may help.
