According to forecasts from the Portuguese Institute of the Sea and Atmosphere (IPMA), from Thursday onwards, “the weather in mainland Portugal will be influenced by a depression, with an expression at altitude, centered over the Madeira region, moving towards the northeast, promoting a circulation from the southern quadrant over the continent and the transport of dust originating in North Africa”.

Thus, an increase in cloudiness is expected for Thursday, “with a low probability of precipitation, which if it occurs will result in the deposition of dust on surfaces”, a situation that is expected to continue on Friday, but with an “ increased instability”, with showers expected from the afternoon onwards, which could at times be heavy, along with hail and accompanied by thunderstorms.

On Saturday and Sunday, the concentration of dust will decrease, with the forecast of showers remaining, more likely in the north and central regions, sometimes hail and accompanied by thunderstorms, until the 10th.

According to IPMA, during this period the wind will blow weak to moderate, predominantly from the southern quadrant, and more intense gusts cannot be ruled out during the occurrence of showers.

In the north and central regions, the maximum temperature is expected to rise on Thursday and Friday, reaching values ​​between 30 and 35°C, being slightly lower on the coastal strip.

On Saturday, the temperature will drop to between 20 and 25°C and may be slightly higher in some inland locations.

In the southern region, the temperature will also increase slightly on Thursday, with values ​​between 30 and 35°C, decreasing from Friday onwards, reaching between 20 and 25°C.

After the drop in temperature on Saturday, the IPMA does not predict significant variations in temperature until at least Monday.
