Recent ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and Global Forecast System indicate a peak daytime temperature in Milan on May 22 likely reaching 28–29 °C, driven by southerly flow of warmer Mediterranean air under a broad high-pressure ridge. This setup favors modest warming above the city’s long-term May average high of roughly 22–24 °C while limiting convective cooling or cloud cover that could cap readings. Model spread remains modest, with most runs clustering between 27 °C and 30 °C, though small timing differences in the ridge’s position could shift the exact maximum by 1–2 °C. Final resolution will depend on official observations from Milan Linate airport, which record the daily high under standard World Meteorological Organization protocols.
