Spain's state Meteorological Agency (Aemet) has activated a yellow alert this Wednesday, 4 August, for high temperatures that could approach 40 degrees in the Andalusian provinces of Cordoba, Jaén, Malaga and Seville.
After a few days break, the terral wind will return and blow hot air onto the Costa del Sol again with forecasts of the mercury hitting 38 degrees.
Aemet said similar temperatures can be expected in the provinces of Cordoba, Jaén and Seville.
All alerts are activated 1pm to 8pm, except in Malaga province, where the temperature is expected to peak between 3pm and 9pm.
As José Luis Escudero explains in his SUR blog, Storms and Lightning, some areas of the Guadalhorce Valley, including Pizarra and Álora, could see the mercury hit 37 or 38 degrees.
