An unseasonal wave of intense heat and calima (dust haze from the Sahara) is set to envelop the Canary Islands, starting mid-week and lasting through at least Sunday. After a period of mild temperatures, overcast skies, and occasional light rain, the islands are now bracing for a sharp increase in temperatures, with the heat surge predicted by the State Meteorological Agency (Aemet).
Starting tomorrow, strong winds carrying African dust will arrive, marking the return of the calima. These dusty winds will primarily affect the eastern islands, with the province of Las Palmas seeing the most significant impact, particularly Fuerteventura and Lanzarote.
Temperatures are expected to climb sharply on Thursday, when highs are forecast to reach around 31°C in Gran Canaria, Fuerteventura, and Lanzarote. Tenerife will experience a slightly cooler but still warm 29°C in its southern regions, while El Hierro, La Gomera, and La Palma should retain more moderate conditions.
The heatwave is expected to intensify further on Friday, with highs of 32°C anticipated in Gran Canaria. Tenerife’s metropolitan area, under a heavy blanket of haze, is forecast to reach 31°C. This unusual October heat spell, exacerbated by the dusty calima, will likely linger through the weekend, reminding residents and visitors of summer-like conditions long past the usual season.
