Hot weather: in northern Italia 35° until tomorrow. In London record temperatures, deaths in France

 London's overnight low reached 19.2 degrees Celsius, an unprecedented high for the month of May in over a century of measurements.

While for today the Met Office indicates highs above 34 degrees, i.e. well above the historical record of 32.4 dating back to 1922.

The BBC's chief forecaster describes these levels as "a crazy thing" and various experts relate them to a more general trend of climate change that has been denounced for years by many at the global level.

The sunny days that accompanied last weekend, extended to today's holiday in the Kingdom, also filled parks and beaches on the island: taken by storm by those who did not leave for holidays beyond the sea.

 Summer is a month early, with highs of 7 degrees above the climatological average and temperatures that in the coming week could reach 33-35 degrees, especially in the Centre-North.

Lorenzo Tedici, meteorologist at iLMeteo.it, last week predicted the first heatwave of 2026 right between 24 and 27 May.

 "We will enter a period characterised by a significant, constant increase in maximum temperatures: the heat will be felt particularly in the central-northern regions, moving clearly above seasonal averages, at least 6-7 degrees," explains Tedici.

 The peak of this first heat wave of 2026 will be on Wednesday 27 May with 35°C in the Po Valley in the boiling triangle of Emilia-Eastern Lombardy-Western Veneto and 32-34°C easily reached over much of Central-Northern Italy.

 In the South and on the Adriatic side, stability will not be able to impose itself absolutely. On these areas, in fact, a cyclonic circulation currently positioned over the Balkans will make its influence felt.

This influx of slightly cooler and unstable air at altitude will keep the risk of local thunderstorms alive, which will affect some sectors of the Apennine ridge.

So, says the weatherman, "summer will try to make its first official entrance, concentrating its maximum effects, however, in the Centre-North and leaving the south to grapple with the last gasps of a typically spring-like instability.

Along with the heat comes back the heat wave bulletin from the Ministry of Health, which maps temperatures in 27 cities, offering 24, 48 and 72-hour forecasts. The situation presents an orange alert in 12 cities (Bologna, Bolzano, Brescia, Florence, Frosinone, Perugia, Rieti, Rome, Turin, Trieste, Venice and Viterbo).

Tomorrow, then, the orange cities become 15: Bologna, Bolzano, Brescia, Florence, Frosinone, Latina, Milan, Perugia, Rieti, Rome, Turin, Trieste, Venice, Verona, Viterbo.

Alert yellow always tomorrow in: Catania, Genoa, Messina, Naples, Pescara, Reggio Calabria.

A severe heat wave is hitting Hanoi and much of Vietnam hard, with temperatures abnormal for the season. According to the National Centre of Hydrometeorology, values of up to 38.8 degrees were recorded in the capital, but in some urban areas the thermometer exceeded the real 40s, as reported by Vietnam News.

The authorities have issued a level 1 natural disaster risk alert, predicting that temperatures will remain between 38 and 40 degrees until 28 May, with even higher peaks in some areas.

Prolonged heat increases the risk of fires, explosions due to peak electrical demand, and health hazards such as dehydration and heat stroke.
