April weather in Spain

Before I decided to permanantly reside on dry land, I used to visit Spain often, particularly during the months of April and May when the weather is more comfortable. Now either the climate has changed since or my heat tolerance level has risen but I am currently finding it a bit nippy to sit out in.

I see British people presumably on holiday that are basking in it and I suppose in contrast for where they come from it must be very hot but I am not yet ready to strip off and I am still wearing my electric fin blanket during the night.
