Brittany. the beaches are splendid you can have wine or cider or try some of the fantastic local beers brewed from traditional black wheat, elderflowers or honey, and if you like folk music ( which as a mudcatter I suppose you do) there is no where better.
The weather is not too hot as it is in the South and there are beautiful forests and even an attempt at mountains (normally called small hills anywhere else in the world, but Bretons are small), but mainly beaches and music...
