Recent high-pressure ridging across northern Italy has driven Milan’s daytime maximum to 31°C on June 13, 2026, with ensemble forecasts from ECMWF and GFS converging on this value in the final model runs. Official observations align with these projections, reflecting typical early-summer warming under clear skies and light southerly flow that limits cloud cover and nocturnal cooling. At 100% market-implied probability, traders reflect the narrow uncertainty band once the daily peak is recorded. Only an unseasonal cold front or revised station data falling outside standard measurement tolerances could alter the outcome before resolution.
