In fact, Gran Canaria is currently under aviso from the Spanish AEMET weather service for dusty conditions (visibility potentially below 3000 metres). North Gran Canaria is also on aviso for strong winds (up to 70kph in the highlands).
The good news is that the dust should fade away today and will be largely gone by Sunday.
On Sunday, the north can expect cloudy weather with the odd shower while the south will be a mix of clouds and sunshine. The south-east will be windy so beachgoers should think about heading to Puerto Rico and Mogán rather than to Maspalomas and Playa del Inglés.
Take care on rocky coasts over the weekend as the south coast will get big waves over the weekend.
Monday will start with some cloud in the south but this will clear throughout the day. Tuesday will be mostly sunny and the temperature will rise.
