Trader consensus on Polymarket has locked in 11°C as the highest temperature in Warsaw on April 26 at nearly 100% implied probability, reflecting tight alignment across official IMGW forecasts, ECMWF high-resolution runs, and GFS model ensembles showing a daytime maximum of 11–12°C at Warsaw Chopin Airport station under partly cloudy skies and gusty northerly winds advecting cool continental air. Current early-morning observations from IMGW synoptic stations already register around 11°C with wind chill, supporting limited diurnal warming amid below-average April conditions (historical highs average 13°C). Realistic challenges include prolonged sunshine boosting solar heating to 12°C or increased cloud cover suppressing it below 11°C; final resolution awaits official 24-hour max from the airport station, with intraday updates from automated sensors potentially shifting sentiment before close.
