Italy Faces Extreme Heatwave as African Anticyclone Returns

Italy is bracing for a significant surge in temperatures as an African anticyclone moves across Western Europe, bringing potential highs exceeding 40°C. Following similar heatwaves in France and Spain, meteorologists anticipate a brief weekend reprieve before intense, persistent heat returns to the Italian peninsula, raising concerns about “tropical nights” and health risks in urban centers.

The Meteorological Outlook for July

According to forecasts from [3Bmeteo](https://www.3bmeteo.com/), Italy will experience a structural weakening of the subtropical anticyclone during the upcoming weekend. This transition is expected to bring localized, intense thunderstorms, particularly across Northern Italy on Saturday, followed by unsettled weather along the Apennines and the Adriatic coast on Sunday.

However, this instability will be short-lived. Experts indicate that the “anticyclonic dome” is set to regain strength rapidly by the start of the following week. Starting Wednesday, July 15, the heat will intensify significantly, with widespread temperature spikes across the country.

Projected Temperatures and Regional Impacts

The intensity of the heat will vary by region, though most of the country will see temperatures well above seasonal averages. The latest projections suggest the following conditions:

* Southern Italy: Expected to reach peaks between 38°C and 41°C.
* Sardinia and Sicily: Forecasters warn of extreme heat, with temperatures potentially climbing to 42°C–43°C.
* Central Italy: Highs are projected to range between 37°C and 40°C.
* Northern Italy: While raw temperature readings may be slightly lower than in the south, higher humidity levels will lead to increased levels of “afa”—or sultry, oppressive heat—making the perceived temperature significantly higher.

The Risk of “Tropical Nights”

A primary concern for health officials and meteorologists during this period is the arrival of “tropical nights.” This phenomenon occurs when nighttime temperatures fail to drop below 25°C. Urban areas are particularly vulnerable due to the urban heat island effect, where concrete and asphalt retain heat throughout the night, preventing natural cooling.

These sustained high temperatures during sleeping hours can lead to heat exhaustion and strain cardiovascular health, particularly among vulnerable populations. Residents are advised to monitor official weather alerts and local health guidance as the peak of the heatwave approaches.

Key Takeaways

• Weekend Reprieve: A minor, temporary drop in temperatures is expected this weekend, accompanied by potential storms in the North and along the Adriatic.
• Intense Rebound: The heatwave will intensify by mid-week, with the most extreme temperatures expected in the islands and the South.
• Health Precautions: With “tropical nights” likely in urban centers, authorities recommend staying hydrated and limiting outdoor activity during the hottest parts of the day.
