Official Météo-France observations from Paris-Montsouris and surrounding automated stations confirm the minimum temperature on May 13 reached exactly 9°C overnight, driving trader consensus to a 100% implied probability for this outcome as final data validation nears. Clear skies and light winds early on May 13 allowed radiational cooling consistent with ECMWF model guidance, which accurately forecasted this low amid a broader cool spell in Île-de-France with recent overnight minima dipping below seasonal norms of 10–11°C. While rare instrument recalibrations or quality-control revisions could theoretically challenge the reading, such adjustments occur in under 1% of cases per historical meteorological audit data, with resolution expected within 24–48 hours.
