Heat warnings in Spain have been raised with an orange alert in effect in nine provinces. Maximum temperatures could exceed 40 degrees and reach a blistering 42C in Campiña Sur.
Much of eastern Spain is under an orange heat warning. Cáceres and Badajoz, the provinces which form Extremadura, are joined by Salamanca, Ávila, Toledo, Seville, Córdoba, Jaén and Ourense in putting out the weather warnings, the Express reported.
The weather may not relent for many residents and tourists. Temperatures are not expected to dip below 39C in Extremadura throughout Monday. Salamanca and Ávila will see 40C, according to forecasting, as will Ourense, in Galicia.
Staying put on a yellow warning for the moment are Andalusia, Madrid, the Basque Country and Aragon. Also under this umbrella of yellow warnings are Catilla y Leon, Catalonia, Navarre and La Rioja.
Temperatures for much of the country between 35C and 38C fall under this yellow warning. Catalonia and Valencia are likely to feel the force of thunderstorms as the day wears on.
The blistering temperatures are expected to last through to the middle of the week. Most of mainland Spain and the Balearic Islands will see the mercury soar above 35C, with Galicia set to record 38C.
Throughout the central region and the capital through down to the south and Mediterranean coast, there will be little reprieve during the nights, with temperatures staying at 35C.
Thundery showers are expected through to Wednesday in northern and central parts of the country,
A spokesperson for Spain's state meteorological service said they were not dismissing the idea that the temperatures would reach heatwave status.
They said: "It cannot be ruled out that it will end up being classified as a heatwave, especially in the southwest of the Peninsula, although it will not be as extraordinary as that of mid-July."
The warnings come just days after Spain's Prime Minister, Pedro Sanchez, called on workers to ditch their ties in an effort to save energy in the heat.
Mr Sanchez told a news conference that by losing the ties, workers will be less dependent on costly air conditioning units. He said: "This means that we can all save energy."
The country has also been hit by a spate of devastating fires in a number of Spanish regions over the past few weeks. Around 200,000 hectares of land are thought to have been lost to wildfires in Spain this year.
