This will cause a continuous thermal rise across most parts of Spain, except for the Mediterranean area, where they will drop.

During these first two days of the week, it is likely that temperatures of 40-42°C degrees will be reached in large areas of the southwestern quadrant of the mainland.

Likewise, values ​​of around 36-40°C are predicted in large areas of the northern half, especially in the northwest quadrant. This will affect areas such as Galicia and the interior of the Cantabrian Sea, where until now, according to AEMET, summer has been relatively cool.
