Recent short-range forecast models from Météo-France and ECMWF show variability in overnight radiative cooling for Paris on July 18, with minimum temperatures hinging on cloud cover, Atlantic frontal passages, and boundary-layer wind patterns that could advect cooler maritime air or sustain warmer continental conditions. Following mid-July heat and thundery showers on the 17th, traders see near-even odds between a dip to 12°C or below versus stabilization near 17°C because ensemble spreads remain wide on dew-point depression and subsidence strength. Upcoming model runs and official guidance will clarify whether clearer skies enable stronger nocturnal cooling below seasonal 15–16°C averages or if lingering moisture caps the low.
