The meteorological summer is coming to an end, and attention is focused on the weather conditions that will mark the beginning of September.
The weather forecasts for the start of autumn indicate a continuation of the intense heat that characterized the summer months, with no significant change on the horizon. The latest weather analyses suggest that the North African anticyclone, the undisputed protagonist of the summer climate, will continue to influence the weather even in the early days of September.
The cool currents coming from the Atlantic, although present, do not seem strong enough to counteract the African heatwave.
Consequently, temperatures will remain high, with peaks of 35-38°C, accompanied by heavy humidity, especially along the coasts.
Coastal cities, in particular, will experience weather conditions characterized by oppressive heat and tropical nights, with minimum temperatures that will hardly drop below 25°C. Weather conditions in the early days of September Extreme heat will dominate at least until September 5, with days expected to be sultry and sunny throughout Northern Italy, Central Italy, and Southern Italy.
The inland and plain regions will be the most affected by the extreme heatwave, while mountainous areas might benefit from some isolated heat thunderstorms in the afternoon hours.
After this date, the weather could follow two different directions.
One scenario sees the persistence of the North African ridge, which could maintain the intense heat until September 10.
This possibility cannot be ruled out, considering the tenacity with which the anticyclone has resisted throughout the summer. Possible change? An alternative possibility is represented by a gradual weakening of the anticyclone under the push of more marked Atlantic disturbances.
This could favor a drop in temperatures, bringing values back in line with seasonal averages.
The first signs of this weather change could occur between September 7 and September 10, with the arrival of cooler currents that could lead to widespread rain, especially in Northern Italy and Central Italy.
During this phase, even Southern Italy could be affected by thunderstorms, although with less intensity and frequency compared to the north. The temperature drop could be more significant in the northern regions, where highs could fall below 30°C, while in Central Italy and Southern Italy the drop will be more gradual but still noticeable.
However, the areas most exposed to the arrival of disturbances will certainly be the Alpine and pre-Alpine regions, which could see significant rainfall accumulations and a more marked decrease in temperatures. Autumn at the door As mid-September approaches, it is likely that weather conditions will become increasingly variable, typical of the seasonal transition.
The shift from a summer to an autumn climate could be marked by an increase in precipitation and greater atmospheric instability, with frequent thunderstorms and a gradual drop in temperatures.
This early autumn scenario could bring temperatures back to more seasonally appropriate values, definitively closing the long summer heatwave that characterized the past few months.
