Spain and most of Europe are about to go Baltic due to a vast blob of freezing Polar air and this will push rain and cool air south towards Gran Canaria. It will affect the north and the highlands much more than the south and the resorts.
South and central Gran Canaria is on yellow alert for wind and waves from 15.00 today Friday, January 26 until at least midday on Sunday. The alert for wind and waves is also active for north Gran Canaria on Saturday.
A new blast of cool air from the north arrives in Gran Canaria just in time for the weekend. It will bring cloud and showers to north Gran Canaria but shouldn't have any effect on the resorts apart from a few cloudy patches.
