Having just returned from Alcudia for 2 weeks I'd say dont even bother with forecasts! In our reception every night they'd watch the local forecast and write it out for us. Each night we would eagerly look on our way out and look forward to a day or sun/sun & cloud/cloud/rain practically each day it was wrong. I'd say go out there, relax about what the weather is going to be like and just see each morning when you get up. Tuesday was supposed to rain all day, not a cloud in the sky from morning till night!
