You can expect all kinds of weather really! We have had 1 full weeks rain, flooding, & power cuts but also been and had 2 weeks rain free. temps in the early 20's are not uncommon in the day time but nights can be a little cool acording to my wife - I don't feel the cold! At the end of the day the weather is not the reason for us going, Arillas is wonderful no matter what the weather is. Watching the storms around the village can be beautiful. Hope you enjoy your stay, we are at the Rainbow for your 2nd week so might bump into you.
Cheers Paul
