Probably - lived there for 8 years. It won't always be sunny but it will be warm-very warm. We are going for April and expecting pretty good weather. Last May the daytime temps were between 20 - 30 degrees with rain on 1 day. June 26-35 no rain
We go to Costa del Sol or the Algarve every year at Easter, usually early - mid April. Temperatures vary between high teens and mid 20s. Occasionally had rain but never for the full week, always warmer than here and usually a lot sunnier. Nothing guaranteed tho.
we're going to southern spain at easter, so am watching the forecast, it's saying it'll be 20 degrees this weekend where we're going (fly into malaga), so i have high hopes! can't manage it too hot myself as i burn easily.
