Trader consensus on Polymarket heavily favors 29°C (39%) as Shenzhen's highest temperature on April 12, closely trailed by 28°C (30%), reflecting tight uncertainty in forecast models amid recent clearing skies. Over the past 48 hours, observations at Shenzhen Bao'an International Airport station—the market's resolution source—hit 29°C peaks as a weak frontal system departed, boosting solar insolation under a subtropical high-pressure ridge. ECMWF and GFS ensembles project consensus peaks near 29°C, but diverge on afternoon cloud persistence and sea breeze timing, which could cap at 28°C via coastal cooling or push to 30°C via urban heat island amplification. Mid-April historical highs average 27°C; watch hourly updates from the Shenzhen Meteorological Bureau for final differentiation.
