Forecast (August 9 – August 13, 2023)

Gran Canaria is expecting an intense heatwave starting from Wednesday, August 9th, and predicted to last until at least Monday, August 13th. The episode of hot weather will not be the first heatwave of the year, but may be the first this summer to meet all the necessary criteria to be officially classified as such by Spanish State meteorological Agency, AEMET, as it will last for more several days with sustained high temperatures.


A mass of warm air originating from the African continent, coupled with Saharan desert dust, known locally as Calima, will lead to an intense and enduring heatwave across the entire island of Gran Canaria. The heatwave is expected to encompass a very large geographical area, affecting multiple municipalities.

The hottest areas will be inland and across the south of the island, with temperatures in the shade as high as 42ºC, much hotter in direct sunlight.  Everybody is advised to be aware of themselves, keep hydrated, and look after those around them, particularly older people and children, and animals.

The north of the island, and the capital, Las Palmas de Gran Canaria, is expected to be much cooler than the south, though top temperatures will still be in the high 20s with a little more cloud cover. 

Top Temperature Trend:
Tuesday, August 8th: Temperatures will remain in the upper 20s.
Wednesday, August 9th: A noticeable increase in temperatures is expected to above 32ºC in the shade.
Thursday, August 10th: Significant rise in temperature, with the hottest conditions expected hitting 40º and above.
Friday, August 11th: Temperatures will remain extremely high, reaching their peak of around 42ºC, hotter in direct sunlight.
Saturday, August 12th & Sunday, August 13th: Continuation of very high temperatures.
Monday, August 14th: A modest decrease in temperatures will begin.
Tuesday, August 15th: A gradual decline in temperatures, with values starting to return to levels prior to the heatwave.
