Peaks up to 40 degrees
During this week a sharp increase in temperatures is expected, with peaks of 36-38 degrees already on Wednesday, July 29, in the internal plains of the Center-North, reaching up to 40 degrees over the weekend. Although the heatwave will progressively affect most of Italy, the initially most affected areas will be the northern plains and central regions.

The Ministry of Health bulletin
The rapid rise in temperatures that will affect large parts of the national territory from tomorrow is evidenced by the daily bulletin of the Ministry of Health on heat waves. Yesterday, the cities with red alert – the highest level of warning – were still zero, only two were orange (Campobasso and Palermo), ten were yellow, and the remaining part of the 27 monitored urban centers was green.
Today, however, the yellow alerts have doubled, reaching twenty, and the urban centers in orange have become three (Messina, Perugia, and Rieti), while Campobasso has turned red. The green alert today remains only in Cagliari, Venice, and Verona.
