Trader consensus on Polymarket assigns a near-certain 100% implied probability to 16°C as Shanghai's highest temperature on April 23, 2026, backed by official observational data from Shanghai Pudong International Airport—the market's standard reference station. Hourly METAR reports from the China Meteorological Administration and aligned sources like NOAA logged peak surface temperatures of 61°F (16.1°C) around mid-afternoon amid northerly winds, lingering cold air masses, and partial cloud cover that capped daytime heating. This aligns with recent cool anomalies, including 18°C on April 22, deviating below April's climatological average high of 19°C due to post-frontal cooling. Realistic challenges would require a data revision uncovering an overlooked higher reading from auxiliary stations, though evening cooling and final tallies render this improbable; resolution awaits CMA's official daily summary.
