Official observations from automated weather stations at Shanghai Pudong International Airport (ZSPD), the market's resolution source, confirm the daily maximum temperature reached exactly 20°C (68°F) on April 4, 2026, driving trader consensus to 100% implied probability. Morning forecasts from the Hong Kong Observatory anticipated a high of 22°C under overcast skies, but persistent cloud cover, mist, and moderate winds capped warming after an early peak around 9 a.m., with temperatures averaging 17.3°C (63°F) through the day. Historical April highs in Shanghai average 18–19°C, aligning with this outcome. Revisions could occur if China Meteorological Administration quality checks reveal sensor anomalies, though such post-validation adjustments are rare for finalized daily records.
