Trader consensus on Polymarket reflects near-certainty (100% implied probability) that Warsaw's highest temperature on March 30, 2026, reached 11°C, driven by official Institute of Meteorology and Water Management (IMGW) SYNOP observations from Warsaw station 12375, which recorded a midday peak of 10.9°C amid persistent northerly winds, mostly cloudy skies, and a cool air mass suppressing further warming. ECMWF and GFS model ensembles had projected highs around 12°C, but real-time data confirmed subdued conditions consistent with recent frontal passages. With sunset at approximately 19:08 local time and temperatures already falling toward evening lows near 2–4°C, no realistic late-day surge is possible barring an unprecedented measurement revision from IMGW's quality-controlled daily summary, expected shortly after midnight. This aligns with March's climatological norms, where daily highs average 7–9°C but vary with shortwave trough influences.
