Recent forecasts from Météo-France and global models indicate Paris will see overnight lows near 14–16°C on July 1, following a late-June heatwave with daytime peaks near 40°C that has begun easing. The primary driver of the 61.5% market-implied probability for 14°C or below is the expected clear skies and light northerly flow promoting radiative cooling after sunset, consistent with climatological July minima around 15°C. Updated model runs show limited disagreement on this range, with any cloud cover or southerly shift as the main variables that could keep the low closer to 15–16°C. Traders are weighting the strong historical precedent for early-July nighttime drops alongside the current transition from extreme heat.
