Official Météo-France observations from the Charles de Gaulle Airport station—the market's resolution source—confirm a peak temperature of 19°C on April 16, recorded around midday under mostly cloudy skies with light winds and no significant precipitation. This outcome matches pre-event ensemble forecast consensus from ECMWF and other models, which projected highs of 17–20°C amid a mild Atlantic airflow slightly boosting temperatures above Paris's April climatological average of 16°C. Trader sentiment at 100% implied probability reflects full alignment with these quality-controlled hourly measurements, underscoring prediction markets' efficiency in aggregating verified data. Realistic challenges are negligible but could arise from rare post hoc data audits revealing sensor errors, though Météo-France's validation processes minimize such risks.
