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.
06.02.2107: If you've watched the Gran Canaria weather forecasts for next week, you'll have noticed that they look a bit gnarly. There's definitely weather incoming but we're not exactly sure what it is yet.
WEATHER FORECAST FOR THE WEEK STARTING FEBRUARY 15, 2016: Gran Canaria is on alert for strong wind and waves on Monday and Tuesday. Clouds and rain are forecast for the north of the island. The south will be windy but could well be sunny.
There's more to Arucas old town than the great big church. Walk up the narrow cobbled streets behind the cathedral for great old Canarian houses and local street life, then head down narrow Calle Gourié to the High Street (Calle León y Castillo).
