Recent forecasts from multiple models indicate overnight lows in Paris on August 23 will likely settle near 12–13°C under mostly clear to partly cloudy skies and light northeasterly flow, following a cooler, drier air mass that arrived after mid-August heat. Radiational cooling under reduced cloud cover and lower dew points should allow temperatures to dip efficiently after sunset, while the absence of strong winds or precipitation limits further moderation. Historical climatology places the average low near 14°C, so the current setup favors values slightly below normal. Trader emphasis on 11–13°C outcomes reflects tight model agreement on these thresholds, with minor divergences in boundary-layer moisture and exact cloud timing determining whether the minimum reaches 11°C or holds near 13°C. Updated runs from the ECMWF and GFS in the next 24–48 hours will refine the precise overnight minimum.
