Recent ensemble guidance from Météo-France and the ECMWF places Paris’s overnight low near 10°C at the Le Bourget reference station, supported by moderating northerly flow and moderate radiative cooling under partly cloudy skies. This aligns with climatological norms for mid-May, when average overnight lows hover around 10°C, driving the overwhelming 97 percent market-implied probability for the 10°C outcome. Traders are incorporating the latest model runs that show limited variability in minimum temperatures. A sharper-than-expected clearing of clouds or a brief wind shift could allow additional cooling into the 9°C range, while persistent cloud cover or warmer advection might push the low slightly above 10°C; resolution hinges on the official station reading at the close of the 24-hour period.
