Italy is experiencing one of the most weather-contrasted days of the summer. While a tornado swept through Cremona in the early hours of Saturday, damaging the cathedral and the town hall, the south remains under the influence of persistent heat, intensified by a cloud of Saharan sand that is casting a milky hue across the sky and has already fallen in some regions as pioggia sporca, or dirty rain. The contrast between north and south stands as a symbol of the unusual summer of 2026, in which stable heatwaves in the south and brief but violent storms in the north are alternating with increasing frequency. Here is an overview of the current situation.
Cremona: tornado damages the cathedral and town hall
On Friday afternoon, a tornado struck the northern Italian city of Cremona in the Lombardia region, accompanied by heavy hail and strong gusts of wind. As the Italian news agency ANSA documents in its coverage, the cladding of one of the cathedral's spires collapsed, and the roof of the Torre civica of the town hall was also damaged, the latter being considered the sole surviving remnant of the earlier town hall built before 1206. Mayor Andrea Virgilio described the current storm episode on his Facebook profile as considerably more severe than a similar event roughly a month earlier, with significant damage to private flats and cars as well. The central squares were closed to visitors, and the Centro Operativo Comunale of the civil protection authority has been coordinating interventions since Saturday morning.
Cremona is internationally renowned as the birthplace of Antonio Stradivari and as a UNESCO World Heritage site for its violin-making tradition . The Romanesque cathedral, with its freestanding Torrazzo, the tallest brick bell tower in Italy at over 112 metres, is one of the most visited cultural landmarks in Lombardia. For those planning a visit to Cremona in the coming days, access to the interior of the cathedral and to the Torrazzo will remain restricted until further notice.
Southern Italy: heat and Saharan rain
While the north is characterised by a variable weather pattern, the south continues to remain under the influence of the African high-pressure system. As the news portal Torresette notes in its assessment of the current situation in Campania, maximum temperatures in some areas of the Campania region are reaching 37 degrees, and the bollino arancione issued by the civil protection authority remains in effect for Napoli, with recommendations for caution aimed at vulnerable groups. Temperatures well above seasonal averages are extending an exceptional heatwavethat began in July and has persisted across southern Italy for weeks.
In addition, the air mass streaming northward from the African continent is carrying large quantities of Saharan sand across the Tyrrhenian Sea into Campania, Calabria and Sicily. The sky is taking on a milky yellowish appearance, visibility is partly reduced, and should isolated rainfall occur in the coming hours, the dust suspended in the atmosphere will descend as pioggia sporca , leaving a characteristic ochre-brown colouring on water, cars and building facades. This phenomenon occurs in southern Italy several times a year, though rarely at this intensity and rarely in combination with sustained record heat.
Meteorological context
The current weather contrast is attributable to the interplay of two high-pressure systems . As the Italian portal Il Meteo documents in its overview of the weekend situation, the African high that has dominated for weeks is partly retreating southward, while the influence of the Azores high is strengthening over the western Mediterranean. This is leading over the weekend to a gradual drop in temperatures across northern and central Italy, while the south will remain under African influence for a few more days.
The boundary zone between the two systems is particularly unstable from a meteorological perspective and is producing localised but very intense weather phenomena such as the tornado in Cremona. Similar incidents have already occurred on several occasions this summer along the Alpine foothills and across the Po Valley, causing considerable damage in some cases to agriculture and infrastructure. The combination of warm, humid air at ground level and cooler air flowing in at altitude is the classic meteorological basis for the formation of such storm systems.
Outlook for the coming days
Over the remainder of the week , a gradual equalisation of weather conditions is to be expected. Sunday should see temperatures begin to fall even in southern Italy, with values slowly returning towards seasonal averages. Along the Alpine foothills and in the north-east, the risk of thunderstorms will remain elevated until Sunday evening, with the possibility of brief but heavy rain showers and localised storms. The Saharan sand will largely dissipate across the south over the next 48 hours, though the precise duration may vary depending on local wind direction.
For travellersdriving in Italy over the coming days, it is advisable to pay close attention to local weather warnings, particularly in the northern regions. Those staying in the south should, in the event of pioggia sporca Cars and terraces should be given a quick rinse to prevent staining. Further details on the current weather situation can be found on the official portals of the Aeronautica Militare and the regional civil protection authorities, which are updated on a daily basis.
