Spain is facing its second heatwave of the summer, with temperatures expected to soar as high as 44 degrees Celsius across parts of the country, the national weather agency AEMET has warned.
Authorities have issued orange and yellow alerts in wide areas as extreme heat grips much of the country.
The worst-affected regions include Andalusia, the Guadalquivir and Guadiana river valleys, the Ebro basin and parts of the northeast.
According to forecasts, Monday was the hottest day so far, but intense heat is set to persist through Tuesday.
While temperatures may ease slightly in some areas from Wednesday, the heatwave is expected to continue for several more days in the southwest.
The impact is also being felt beyond the mainland. In the Canary Islands, including Gran Canaria and Tenerife, authorities have raised wildfire alerts due to the heightened risk caused by extreme heat and dry conditions.
Experts warn that high night-time temperatures—ranging between 20 and 28 degrees Celsius—will lead to “tropical nights,” making it difficult for people to rest and increasing health risks.
The latest heatwave follows an earlier one in June that reportedly caused around 900 excess deaths, according to data from Spain’s health ministry cited by local media.
Officials have urged residents to avoid going out during peak afternoon heat unless necessary, stay hydrated, limit strenuous outdoor activities and take special care of children, the elderly and those with chronic illnesses.
