Trader consensus at 100% for a 6°C low in Paris on October 12 reflects current observational data and short-range model output showing overnight radiative cooling under mostly clear to partly cloudy skies, with minimum temperatures bottoming near that threshold at official stations. Calm southerly flow and dew points supporting efficient heat loss overnight have aligned forecasts from sources like GFS around this value, consistent with autumnal patterns where clear periods allow temperatures to dip below the seasonal average low near 9°C. Resolution hinges on the final verified minimum from the primary Paris weather station before midnight local time. Unexpected increases in cloud cover or a late wind shift could limit further cooling and shift the recorded low higher, though current conditions make such deviations unlikely.
