Honestly, I could book a trip to Australia in the middle of their summer and it would piss it down with rain and be 10 degrees @Devil-Dick Willie, @Toinho
Saying that, I wasn't going to South Spain for the weather, or I wouldn't have booked it for March, but you'd still expect it to be sunny and 18 or so degrees, which would be perfect for visiting the Mountainous areas and exploring local towns. I'm only using Benalmádena as a base as it's literally central to everywhere I plan to visit, I know someone there, I'm a member of a cannabis social club(for the evenings) and it's easy to reach from Málaga airport, which is ideal. But heavy rain will pretty much ruin all plans.
Funnily enough, I chose March rather than January as I thought the weather would be better, but it was actually far nicer in Jan . I should have gone to the Canaries this time, or even Cape Verde.
