But the rain is expected to continue until the end of the month, according to forecasts from the Portuguese Institute for the Sea and the Atmosphere (IPMA).

Meteorologist Maria João Frada explained to CNN Portugal that this increase in temperature is related to a flow from the south over the Iberian Peninsula that brings "high temperatures", especially in the interior of the Alentejo, such as Évora and Beja, where maximums can reach 28 degrees.

In the rest of the country, maximum temperatures should rise slightly, between one and three degrees above average, being above 20º in most of the territory - Guarda and Bragança are the only regions below this threshold.

According to IPMA forecasts, Santarém could reach 26 degrees maximum and 15 degrees minimum, followed by Sines and Faro, where thermometers should reach 25 degrees maximum and 18 degrees minimum. In Aveiro, Leiria, Lisbon and Setúbal, a maximum of 24º is expected and minimum temperatures are to be around 16º.
