It is the quality of the light too
@arty zan in winter hubby says the light is grey..the sky is grey..the people are grey in the UK.
Where as here it can get bitter cold..but you are blue sky..
Get an oil filled radiator..all the cold comes through the floor in Spain...
..the heat on the air conditioning units ain't good.
Every new year when we went to Lanzarote we were Lucky it was shorts and t shirt weather..but friend went a year we missed and they had terrible weather..
..high winds and rain.
So..you never can tell.
Are you in a Holiday type house/apartment...?..coz they tend to be designed to keep you cool in summer rather that warm in winter.
