Trader consensus on Polymarket heavily favors 25°C (34%) and 26°C (33.5%) as Shenzhen's highest temperature on March 22, driven by ensemble weather model forecasts from ECMWF and GFS converging on afternoon peaks of 25-26°C under a persistent subtropical high-pressure ridge. Historical March data from the China Meteorological Administration shows Shenzhen averages 23-25°C highs, but urban heat island effects and elevated South China Sea surface temperatures (around 24°C) boost potential by 1-2°C. Differentiating factors include minor model spread on cloud cover—clearer skies favor 26°C via stronger solar insolation, while scattered afternoon convection could cap at 25°C. Traders should monitor CMA's 18:00 update for refined guidance amid low wind shear.
