Rest of the weekend looking OK. Partly cloudy in both regions with some nice sunshine coming through. Temperatures will be up at around 20*C+ on the Costa Del Sol, and a similar story on the Costa Blanca, but maybe just a touch cooler here.
Moving into early next week some extensive cloud pushing into the Costa Blanca with some showery rain to contend with, this should not amount to too much. The Costa Del Sol should stay sunny for the most part though temperatures will tumble back to below 20*C in this region.
Moving into the midweek period and things turning really chilly the Costa Blanca may struggle up to 10*C with the Costa Del Sol limping in at a mere 13*C. thick cloud likely on the Costa Blanca with light rain. The Costa Del Sol keeping dry for now.
Moving into Thursday and Friday and still things stay cold, a ground frost is even a possibility! Cloud will break over the Costa Blanca to allow chilly temps of 10*C mainly. Down on the Costal Del Sol more extensive cloud and rain will push in from the East it may be heavy and intense and could last quite a while! Temperatures do not recover for the rest of the week and the rain over the Costa Del Sol will probably stick around until early Friday!
Summary
Nasty week again, cold for the time of year, ground frosts at times with some heavy rain likely over the Costa Del Sol. The Costa Blanca may get away with just showery rain. Not much improvement into next weekend.
