I would recommend the greener, cooler, wetter bits up north, Philip, if you think you'll be staying long-term, though I imagine no such plan has yet formed. But even now, extreme summer heat and water shortages are becoming a bit of a worry in the south and centre.

If you don't mind a fair bit of British drizzle and grumpily overcast skies for half of the year, Galicia, Asturias, Cantabria and the Basque Country are lovely. There are ferries back to Blighty, too. I won a bottle of champagne in the bingo once on the Santander-Plymouth crossing.

Asturias comes with the bonus of getting to drink cider poured into a glass at waist height from a bottle above your head. You could live to be 91 and still be mastering the art of not spattering it all over your shoes. Though I guess the learning curve begins to droop some time in one's 70s, along with all the rest of it.
