Because of this the Portuguese Institute of the Sea and the Atmosphere (IPMA) has placed seven districts on red alert.


Beja, Évora, Portalegre, Castelo Branco, Santarém, Viseu, Vila Real and Bragança are expected to have the highest temperatures, with Castelo Branco being the hottest of all, with 42º.

The remaining districts of the continent will be under an orange warning (the second most serious), also due to the hot weather,.

During the night, minimum temperatures will also be high, "with values above 20°C (tropical nights) in much of the territory, and may not even drop below 25°C in some places in the Algarve, Alentejo and Beira Interior".

The IPMA predicts that temperatures will only begin to drop in a generalised way from Friday, "reaching normal values for the time of year on the weekend of the 26th and 27th".

The rise in temperature is related to "an anticyclonic ridge that extends from the Azores to Central Europe, promoting the transport of a mass of hot and dry air originating in North Africa over the territory of the continent".
