Trader consensus on Polymarket heavily favors a Shenzhen high of 26°C (50%) or 25°C (34%) for March 22, driven by ensemble weather model outputs from the European Centre for Medium-Range Weather Forecasts (ECMWF) and China Meteorological Administration, which project daytime peaks in the mid-20s Celsius amid partly cloudy skies and moderate southerly winds. These align with Shenzhen's subtropical climate norms, where late March historical highs average 24-26°C, tempered by coastal sea breezes that cap urban heat island effects. Recent developments include a slight downward revision in GFS model runs over the past 48 hours due to increased cloud cover forecasts, shifting odds away from 27°C+ while boosting 25-26°C probabilities; official observations from Bao'an station will resolve the market.
