After several days marked by temperatures well above normal for early September, mainland Portugal is preparing for a sudden change in weather. A polar air mass is approaching the territory, causing a significant drop in temperatures.
The temperature drop will be particularly sharp between today and Wednesday, with temperatures possibly falling by up to 9 degrees in various regions of the country. This change represents a huge contrast to the previous days, which had recorded values well above the climatological average for this time of year.
The cold arrives after a prolonged period of anomalous heat, something unusual for early September in Portugal. The meteorological authorities are alerting to the need for adaptation to this sudden change in atmospheric conditions.
