South Gran Canaria and the resorts will be sunny every day. 

The Trade Winds will keep temperatures mild with maximums no higher than 30ºC and minimums of 22ºC. That's about as perfect as it gets for sunny holiday.

The only part of the island that will get some cloud is the north coast and even here it should fade in the afternoons. 

It's still hot up in the mountains so walk early and carry plenty of water. 

The sea temperature around Gran Canaria is currently 21ºC.
