Trader consensus on Polymarket heavily favors a Shenzhen high of 26°C (45.5% implied probability) on March 22, driven by ensemble weather model forecasts from ECMWF and GFS converging on this peak amid a stable high-pressure ridge fostering mild advection of warm air from the north. Recent observations confirm the trend, with March 20 recording 25°C and March 21 forecasts aligning at 25-26°C under partly cloudy skies and light winds, per China Meteorological Administration data. Subtropical humidity and urban heat island effects in Shenzhen bolster these upper-20s odds, though coastal sea breezes introduce uncertainty that slightly elevates 25°C (29.5%) while capping hotter outliers below 10%. Historical March averages hover at 24-25°C, positioning 26°C as a data-aligned frontrunner ahead of tomorrow's observations.
