Latest Météo-France guidance and ECMWF ensemble forecasts position 17°C or higher as the leading outcome at 46% market-implied probability for Paris's highest temperature on April 4, driven by anticipated high-pressure ridge development ushering southerly flows and reduced cloud cover after late-March northerlies limited highs to around 12°C on March 29. Early April climatological highs average 13-14°C per historical Paris-Montsouris data, yet long-range outlooks signal slightly above-normal conditions, with model means clustering near 15-16°C and warmer tails boosting the top bin. Traders note 14-16°C alternatives at 20-21% amid 5-day uncertainty from evolving upper-air patterns; expect shifts from twice-daily ECMWF updates resolving via official station observations.
