I'm not sure why you want to go abraod. If its because its cheaper fair enough. But it can be done quickly in the UK if you ge the right team together and ahve the right approach.
My brother did the full JAR PPL (OK he had 5 hours logged when he started but you say you have 10) in 12 days at Inverness in Sept 2002 (mad-jock will back this up) -no thats not a typo, 12 days in a Scottish Autumn. Its extremely hard work but you fly 3 times a day (in fact he flew with me (hour building) between lessons so he was probably flying at least 5 times a day) and you must have all the ground exams out of the way to allow you to concentrate on the flying but it is do-able.
I suggest you find an instructor who can be exclusively yours all day for however long and get on with it-the weather shouldn't be too much of a problem. Certainly in Scotland the weather changes so quickly that part of every day is usually flyable in some capacity.
Hope that helps. By comparison my PPL took a lengthy 3 weeks one sunny august in Kent ten years ago!!
