We always go to Tenerife in December. Early in December they had a lot of rain.
(It was strange to see the usual dry arid landscape so green!)
We only had a bit of rain for 1 day so we were lucky.
We were in the clothes we wore in September (washed!!!) but needed our arms covered up in the evening.
I think the main problem with the Canaries is the wind but that can happen any time of the year.

thanks for reply suzie

I have been to all the Canaries during our winter and found Gran Canaria the hottest.(January)
Tenerife the cloudiest(January)
Lanzarote the windiest(April) Fueteventura the coldest at night(February)
