Official observations from the Warsaw Chopin Airport weather station (EPWA), the standard reference for such markets, recorded a maximum temperature of 12°C on April 11, anchoring trader consensus at 100% implied probability for this outcome. Cool northerly winds and extensive cloud cover limited solar heating throughout the day, consistent with Institute of Meteorology and Water Management (IMGW) synoptic reports and ECMWF model runs forecasting highs of 11–13°C amid a transitional spring pattern. April climatological averages near 13°C provide context for this mild variability, with no significant deviations noted. Rare post hoc data revisions from quality checks represent the only realistic challenge, though initial airport telemetry is highly reliable.
