L'Italia ha vissuto settimane di caldo e afa dominati dall'anticiclone africano.
After weeks of oppressive heat and sultriness dominated by the African anticyclone, the meteorological picture in Italy is about to change. The first storms are expected from Sunday, an unmistakable sign of a deeper turning point expected for next week.
The turning point Mattia Gussoni, meteorologist at iLMeteo.it confirms that Sunday will mark a first turning point at a hemispheric level with the arrival of thunderstorms in the Alps, Pre-Alps and nearby northern plains. The showers will extend in the afternoon hours also to the central-southern regions. In the rest of the country, however, we will have even greater clearing with temperatures above the reference climate averages.
The storms The real turning point is expected next week when two disturbances are expected to pass. The first will materialize immediately on Monday 17 August, initially affecting Northern Italy. The entry of cooler air at high altitude, colliding with the massive thermal energy accumulated in these hot weeks, will trigger exasperated thermal contrasts. Therefore, storms of strong intensity are also looming, in particular in eastern Liguria, the Alps, the Pre-Alps and the nearby flat areas of Lombardy, Veneto and Friuli-Venezia Giulia.
Seasonal averages Rainfall will then also reach parts of the Center-South by the evening. Once this outburst is over, the atmosphere will give us a break between Tuesday and Wednesday. The sun will return to dominate the scene, giving large sunny spells, but in a decidedly more pleasant climate: temperatures will suffer a general drop, settling at values finally in line with seasonal averages, far from the extremes of the last period.
But the truce will not last long. The latest updates confirm an even more eventful scenario for the second part of the week: a second Atlantic attack, which promises to be particularly incisive and well organised, will reach Italy starting from Thursday 20 August. This deep depression structure will deliver a knockout blow to the African anticyclone. New widespread strong thunderstorms are expected, especially in the Centre-North and, above all, a drop in temperatures capable of definitively wiping away the oppressive heat that has accompanied us until today.
In short, from next week we will see a decisive turning point at a hemispheric level, with the return of disturbed currents. Let's not expect the end of summer, on the contrary, the season will continue later without any particular problems (apart from the strong but localized storms) but with temperatures this time more suited to the period and our latitudes.
In detail Sunday 16. In the North: sun and heat, but thunderstorms in the Alps, Pre-Alps and places in the plains. In the Center: sun and heat, some showers in the mountains. In the South: prevailing sun.
Monday 17. In the North: thunderstorms especially in Veneto and Friuli. In the Center: possible showers. In the South: sunny, local rain in the mountains.
Tuesday 18. In the North: sunny. In the Center: sun, rainy places on the Abruzzo mountains. In the South: thunderstorms in the mountains, sunshine elsewhere.
Trend: mostly stable weather on Wednesday. then comes an Atlantic disturbance

Ferragosto con caldo estremo in Italia, ma da domenica 16 agosto inizieranno a colpire le prime tempeste che porteranno un calo delle temperature, segnando la fine della quarta ondata di caldo.

Dopo giorni di caldo intenso, il maltempo torna al Centro-Sud con allerte gialle in sei regioni. Tuttavia, 19 città sono a bollino rosso per il caldo, con temperature elevate e notti non rinfrescanti.

La settimana prima di Ferragosto sarà caratterizzata da una forte stabilità atmosferica con temperature ben sopra la media stagionale. Si prevedono picchi di 40°C in alcune aree.

Un anticiclone nordafricano domina l'estate italiana, con un breve intervallo di temporali al Nord venerdì, prima di un nuovo picco di caldo estremo a partire da lunedì, coinvolgendo gran parte dell'Europa.

La quarta ondata di caldo africano del 2026 è iniziata con picchi di 38-41°C. La fine è prevista per il 12-13 agosto, ma potrebbe prolungarsi fino a Ferragosto. Il riscaldamento globale aggiunge 4°C, rendendo la situazione estrema.

Domenica 26 agosto, temporali nel Centro-Nord a causa di un fronte temporalesco. Dal lunedì 27, prevista una risalita delle temperature con la 'quarta ondata di calore dell'estate 2026'.
