Wednesday will be clear in the morning with cloud building over the island during the day. This is because the Trade Winds are weak and evaporation from the highlands will firm cloud. This cloud could well reach the coast in the afternoon and there may be the odd shower.
On Thursday the Trade Winds pick up so the north will get cloud while the south will be sunny for most of the day. There could still be clouds in the afternoon over the resorts.
On Friday and Saturday, expect some cloud in the north and sunshine in the south of Gran Canaria.
Shade temperatures are currently about 22ºC in south Gran Canaria.
The water temperature around Gran Canaria is about as cool as it gets with surface temperatures at 19ºC. Shallow water close to the shore is warmer.
