Overview
- Forecasts show a large subtropical anticyclone is expanding over the Mediterranean and will dominate Italy’s weather, ending the recent unstable and cooler spell.
- Early in the hot spell daytime highs are expected around 33–34°C in major Centre‑North cities, with values rising further when the pattern strengthens later in the week.
- Models indicate the most intense, more humid phase will develop by midweek as subtropical air masses push north, increasing the heat stress in cities and lowlands.
- Coastal sectors on the Adriatic and parts of the Ionian coast should see slightly lower maxima because of northerly winds, while inland and mountain areas may still get isolated convective showers or thunderstorms.
- Forecasters warn the heat will bring above‑average temperatures and growing discomfort for residents, raise demand on energy and water supplies, and pose risks to agriculture and vulnerable people.
