Recent post-heatwave moderation across northern France, with weakening high pressure and increasing northwesterly flow, is the main driver of trader positioning for Paris minimum temperatures on July 6. Ensemble guidance from Météo-France and ECMWF shows spreads centered on 15–18 °C overnight lows, with radiative cooling under clearer skies favoring the lower end and increased cloud or maritime advection keeping readings higher. Urban heat-island effects and variable boundary-layer moisture add further uncertainty within a narrow 2–3 °C window, explaining the tight clustering around 13–16 °C outcomes. Upcoming model runs and official bulletins through July 5 will likely sharpen resolution criteria for the observed minimum at Paris-Montsouris.
