The flies are always a pain.  Worst time is april/may then september/october but last year they seemed to be around from the end of august until early december - you really do need a fly free zone to eat outside!

Well, Teruel - it's fairly high compared to Tortosa.  Someone I spoke to who lives in that direction (and who used to live in Northern Scotland) said he had never seen a blizzard like the one he saw up there.  Expect hard frosts and snow in the winter and scorching heat in the summer.

Jools (who lurks round on here from time to time) may be able to add to this as she lives in Aragon.

For example, yesterday (10th Jan) the temperature in Teruel ranged from -3 to 14 Tortosa ranged from 6 to 16.
