Similar phenomena in other countries. So there is a standard joke in the UK - “Weather warning: Southerners are urged not to travel unless absolutely necessary. Northerners, you will need your big coat.” And a friend said the coldest he’d been was in Spain in winter in an unheated house. Though suspect it was no colder than houses we’ve stayed in in Scotland with no central heating. Not complaining about the relatives at all - the welcome was always warm and a wee dram was warming.
When we rented the stone house farther up in the shade of the mountain it was cold in February. No south facing windows and located on the north slope of a mountain in any case. Six hundred years old and beautiful, but not designed for warmth. And actually many places in Cyprus were not traditionally built to withstand cold. Summer heat was the greater problem and still is. But we’re lucky in the flat we’re in. Big south facing windows on one side and north facing ones on the other. If the sun is out, and there’s an average of 300 days of sunlight a year, it’s never cold on the south side. There is a heater but we haven’t turned it on.
