We've been to Provence at end of May and end of October. Both times it's lovely; warm but not too hot, but we're looking to go again but because of work and school could only do end of August. Dp have been at beginning of September and said its nice and not too hot, so wondering if August will be doable. We will have a pool but I'm not good with very hot and we want to be able to go out and explore a bit and not so hot we just can't do anything.
We are also considering leaving a day early and stoping off via tgv at eurodisney in the way down if anyone knows about or has done is and whether it works well.
