Confirmed peak temperature observations from Wuhan Tianhe International Airport reached 29°C around 3 p.m. local time on April 18, driving trader consensus to near-certainty on this outcome as implied by Polymarket odds. China Meteorological Administration (CMA) data, corroborated by ECMWF and GFS ensemble forecasts converging on 27–29°C daytime highs amid hazy sunshine and light winds, aligned with this positioning ahead of peak hours. With sunset now past and temperatures cooling to the low 20s°C under clearing skies, the diurnal cycle precludes further warming. Realistic challenges would require a rare post-sunset measurement revision or outlier station data exceeding airport readings, both improbable per standard meteorological protocols. Final CMA daily summary expected within 24 hours.
