They say it about the CDS too. At a guestimate it would barely reach 300 days.
Well, I guess CDS is between Valencia and Faro. 😀
To be honest, the sky was California-blue 24 hours/day during all my 8 days in Mijas area. In Murcia last year it rained one day in July. In El Campello the sky was cloudy every morning and evening (but sunny at noon and in the afternoon).
So maybe CDS has the sunnier sky in July-August.
