Latest ensemble forecasts from ECMWF, GFS, and Météo-France models converge on a maximum temperature of 13°C for Paris on March 25, driven by a persistent northerly airflow bringing cool, stable conditions with light cloud cover and low diurnal heating potential. Official observations show recent days averaging 11-12°C, aligning with seasonal norms for late March (historical max around 13°C), reinforcing trader consensus at 98.8% implied probability. This positioning reflects model agreement within 1-2°C uncertainty bands. Realistic challenges include an unforeseen warm advection from the south or prolonged clear skies boosting insolation by 2-3°C, though low-pressure persistence makes such shifts unlikely per current synoptic charts.
