**Forecast models from sources like Open-Meteo and GFS project a peak temperature near 20°C in Milan on October 13, 2026, under stable high-pressure conditions with mostly clear to sunny skies and light southeasterly winds.** This setup favors daytime solar heating without significant cloud cover or precipitation, consistent with the market-implied odds favoring 20°C (60.5%) and 21°C (32%). Mid-October climatology for the Po Valley typically sees highs around 18–20°C, and current observations align with gradual warming through the afternoon before evening cooling. Real-time station data and final official readings will determine resolution, with any model shifts or unexpected cloud development as the main variables that could adjust probabilities before the close of the trading day.
