Trader consensus on Polymarket assigns a 99.8% implied probability to a 22°C high temperature in Shanghai on March 30, driven by official hourly observations from the Shanghai Pudong International Airport station—the market's resolution source—which peaked at 22°C around midday local time per recent METAR reports (e.g., 22/17°C at 1500 CST amid light rain). Increasing cloud cover and precipitation, as confirmed by China Meteorological Administration monitoring, have suppressed further warming despite earlier model runs suggesting potential for 20–23°C. Historical March averages hover near 15–18°C, making this a mild outlier. Realistic challenges include improbable late-afternoon clearing for solar reheating, with final CMA daily maximum report expected post-midnight.
