Official observations from Shanghai Pudong International Airport—the market's resolution source on Weather Underground—confirm a daily maximum temperature of 16°C on April 21, 2026, under persistent overcast skies, light rain, and northerly winds at 3–15 mph that suppressed daytime heating. Morning readings near 14°C aligned with China Meteorological Administration guidance and forecast model consensus capping peaks amid a cool air mass. This positions trader consensus at near-certainty for 16°C, reflecting verified hourly data through late afternoon. Realistic challenges include an improbable late-day clearing boosting solar insolation to 17°C before sunset or post-finalization data revisions, though current station records show no such exceedance. Final ratification expected within 24 hours.
