Go to Arizona. Guaranteed 363 days/year of flying.
Doing a PPL (or an IR) in the US is a full time project where you sit the exams, get the medical, get the visa/tsa stuff done, buy the plane tickets, go there, get your head down and FLY solidly. No boozing, clubbing, shopping. You don't want anything that will introduce risk into this.
There will be plenty of time to learn about British weather when you get back here. It's no rocket science to read TAFs etc, but doing the training at the same time just makes the PPL take a year, which is how long most people take in the UK. Most lessons get cancelled. of course the traditionalists say this makes you a better pilot, etc.
