Official observational data from the Warsaw Chopin Airport meteorological station, Poland's primary reference for such markets, recorded a maximum temperature of 12°C on May 13, locking in trader consensus at 100% implied probability for that outcome. This aligns with Institute of Meteorology and Water Management (IMGW) frost warnings during a mid-May cold snap—"zimni ogrodnicy"—featuring northerly winds, persistent cloud cover, and overnight lows near freezing that capped daytime highs. Model ensembles from ECMWF and GFS converged on subdued temperatures in final advisories, reflecting upper-level troughing over Central Europe. Scenarios challenging this include rare post-processing revisions for sensor anomalies, though quality-controlled data from established stations rarely shifts beyond 0.5°C.
