Recent short-range forecasts from Météo-France indicate Paris remains under a heatwave pattern through July 9, with daytime highs near 35°C and overnight lows likely holding around 20°C amid persistent warm advection and limited radiative cooling under partly cloudy skies. This setup favors minimum temperatures in the 19–22°C range over typical early-July climatological values of 14–17°C, explaining elevated market-implied probabilities clustered between 18°C and 25°C. Model consensus shows modest uncertainty from potential northwest flow shifts or clearer nights that could allow brief dips toward 18°C, while stronger high-pressure persistence would keep readings above 20°C. Traders are weighting these variables against historical analogs of heatwave minima, with fresh ensemble updates from European and global models expected to refine probabilities before resolution.
