Trader consensus has converged on a 19°C low for Paris on May 25 because official observations at Paris-Le Bourget Airport recorded a minimum temperature that falls squarely in that bin, with clear skies and a stable warm air mass limiting overnight radiative cooling. Recent model guidance from European and global ensembles aligned closely with this outcome, showing daytime highs near 27°C and morning readings holding above typical May climatology of roughly 11–13°C. The negligible probabilities on all lower bins reflect the absence of any frontal passage, cloud cover, or northerly flow that could have driven temperatures further down. Only an unexpected late-day measurement revision or station-specific anomaly could alter resolution, though such revisions are rare once preliminary data stabilize.
