Official observations from Warsaw Chopin Airport station, the market's resolution source managed by Poland's Institute of Meteorology and Water Management (IMGW), recorded a peak temperature of 20°C on May 1, 2026, aligning precisely with the 100% market-implied probability for this outcome. This measurement reflects predominantly clear skies and light winds that allowed daytime highs to reach typical early-May levels, consistent with climatological averages of 18–20°C for Warsaw during this period under neutral atmospheric patterns. Pre-event forecasts from ECMWF and GFS models had converged on 19–21°C maxima, bolstering trader consensus. Realistic challenges would require a post-audit revision uncovering an overlooked higher reading from hourly METAR reports—highly improbable given standardized instrumentation and real-time verification—potentially shifting odds only if discrepancies exceed 2°C. Final IMGW data release expected within 24–48 hours.
