Sweltering temperatures are expected across much of Spain‘s mainland and islands on today and tomorrow.
The country’s state weather service has issued a “special notice” for rising heat until the middle of the week.
More than 30 regions of Spain will be under orange weather warnings by tomorrow.
A number of yellow warnings are also in place across much of the mainland, the Balearic islands and the Canaries.
A map shows exactly where searing temperatures are expected to hit this week.
The mercury is set to be highest in the Cadiz, Cordoba, Huelva and Seville regions at 40C.
Huesca and Zaragoza are also expected to hit 39C.
Meanwhile, UK Foreign Office officials continue to warn Brits travelling on their holidays over the heat in Spain.
The “special notice” issued by Spain’s weather service adds: “In the coming days there will be a progressive rise in temperatures in much of the Peninsula and the Balearic Islands.”
The warning says the high temperatures are expected to last until Thursday.
Temperatures are expected to reach their highest on Monday and Tuesday.
The notice continues: “Monday and Tuesday will be the peak days of this episode.
“It is probable that 40C will be reached or exceeded in large areas of the southwestern and northeastern quadrants of the peninsula.”
People have also been urged to drink water frequently, avoid booze, pay attention to those with health difficulties and to wear light, baggy clothes.
The forecasters said that after Wednesday there is a “high degree of uncertainty” in the forecast – but the hot weather could break.
The warm conditions may make way for showers and thunderstorms.
It comes after many parts of Europe have faced a hot summer – with blazing heat in holiday destinations such as Spain and Greece.
Weather experts have declared 2023 an El Niño year – a natural phenomenon that occurs cyclically and causes fluctuations in the global climate.
