Staying in Adeje for two weeks from 11th May, looking at some of the forecasts on the internet it doesn't look like the weather will be much better than it is here at the moment ! . Is it going to be warm?can we stay by the pool or beach all day without feeling chilly as my son is going to want to be in & out the water all day ? Also what about night time will it be cool - just wondering whether i will need long sleeves or not !! ? I know i am probably fretting for nothing but it would be nice to have a little reassurance that we can expect it to be warm. Hope someone can help me :-) never been to Tenerife before by the way.
