Forecast models from sources including Météo-France and GFS consensus place Paris's daily minimum temperature on October 15, 2026, near 10–11°C under a stable high-pressure regime with light southerly flow and mostly clear skies after early clouds. This setup supports modest nocturnal radiative cooling without the deeper chill of northerly advection, aligning with climatological October averages around 9–11°C. Trader consensus at 99.4% implied probability for exactly 10°C reflects this tight forecast range and limited downside risk from current observations. A sharper cold front or station-specific microclimate effects could shift the recorded low, though model agreement and benign conditions make such outcomes unlikely before resolution.
