Latest ensemble forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) and Météo-France project Paris highs of 17–19°C on April 4, driving trader consensus toward 17°C or higher at 68.5% implied probability, as a persistent high-pressure ridge ushers mild southerly airflow and partial sunshine above seasonal norms of 13–14°C. Recent model runs over the past 24 hours show strong agreement on these levels, with minor risks from early sprinkles or increased cloud cover potentially capping temperatures at 16°C (18.5%). Observations from Paris-Montsouris station on April 3 reached around 14°C, aligning with steady spring warming trends. Final hourly data releases tomorrow will confirm the peak, amid inherent short-term forecast uncertainty.
