Official IMGW observations at Warsaw Chopin Airport confirm the highest temperature reached 13.2°C at 15:00 local time on April 1, driving Polymarket traders to 100% consensus on 12°C or higher, as multiple METAR reports corroborate peaks around 13°C amid partly cloudy skies and light northerly winds. This aligns with typical early-spring diurnal warming in Warsaw—overnight lows near 2°C giving way to afternoon highs boosted by solar insolation—matching ECMWF and GFS model consensus projecting 12–14°C. Final resolution awaits Wunderground's compilation of whole-degree data from the station; post-finalization revisions are ignored. Realistic challenges, like data errors or unverified station anomalies, are improbable given redundant aviation observations.
