Recent ensemble forecasts from the ECMWF and Météo-France place the highest temperature in Paris on May 18 within a narrow 15–17 °C band, driving the close market split with 16 °C holding the edge at 39.5 % implied probability. Moderate southerly flow under variable spring cloud cover is limiting daytime heating, while ensemble spreads reflect modest uncertainty tied to the exact timing of any weak frontal passage. Historical mid-May averages near 18 °C provide context, yet current model consensus favors slightly cooler outcomes. Updated runs expected before official verification could shift probabilities if guidance trends warmer or cooler.
