bejay,

Try a weather forecasting website such as Wunderground. They give forecasts for different times of the day so you know what to expect. It's forecasting 16-19c in the evenings for next week at the moment.

Just got back from Malaga this afternoon.
Sun, Mon and Tuesday was cool because of the wind, it wasn't a warm wind and you needed a coat especially walking on the promenade. We were in Malaga city on Tuesday and we had jumpers and lightweight jackets on, it was 'nippy' and spitting with rain at times.

Wednesday, Thursday, Friday and Saturday it was glorious wall to wall sunshine and temperatures in the 30°s - no coat needed at night, the wind had changed direction and it was a warm breeze at times.
When we left this morning it was cloudy with that cool wind again, so, I think it's safe to say that you need to take something warm to be on the safe side.

Viento = wind. You can see on the link how the wind changes direction.
