Recent forecasts from multiple models indicate a mild overnight period for Paris on September 4, 2026, with minimum temperatures most likely settling between 17–20 °C under partly cloudy skies and light southwesterly to westerly flow. High pressure and a stable air mass limit radiative cooling, while dew points near 15–17 °C and minimal wind shear support the market’s concentration on 18–19 °C outcomes. These values sit well above the 1991–2020 climatological average low of roughly 13 °C for the date, reflecting the current warm anomaly. Model consensus shows little disagreement through the short-range window, though subtle shifts in cloud cover or boundary-layer mixing could still adjust the final reading by 1–2 °C before resolution. Updated runs from Météo-France and ECMWF over the next 24–48 hours will provide the clearest guidance on whether the low trends toward the upper or lower end of the favored range.
