Official Météo-France observations at the Paris-Montsouris station—the authoritative source for resolution—recorded a maximum temperature of 15°C on April 20, 2026, under persistent cloud cover and a cool northerly flow that capped daytime heating. This outcome matches the latest AROME high-resolution model runs and ECMWF/GFS ensemble consensus from April 19, which projected highs of 15-16°C amid low-insolation conditions typical for mid-April climatology (historical average ~15.5°C). Trader consensus at 100% implied probability reflects this verified data, with real capital aligning on the skin-in-the-game certainty of finalized measurements. Realistic challenges are minimal but could include rare post-audit revisions from auxiliary sensors validating a marginally higher reading, though standard protocols finalize station maxima within hours.
