Recent observational data from Warsaw Chopin Airport and regional stations indicate the overnight low reached 5°C amid clear to partly cloudy skies and light winds promoting radiative cooling, aligning with numerical weather prediction consensus from models like GFS. This positions the 5°C outcome at near-certainty in trader consensus, reflecting verified minimum temperatures rather than forecasts. Historical October averages for the area hover near 8–9°C lows, making this reading cooler than typical but consistent with current synoptic patterns. Only a significant late-day measurement revision or station-specific anomaly could realistically alter resolution, though such shifts remain unlikely given multiple confirming reports.
