Trader consensus on Polymarket strongly favors a highest temperature of 27°C in Shenzhen on March 22 (78.5% implied probability), propelled by the latest forecasts from the China Meteorological Administration and ECMWF models projecting daytime highs peaking there under clear skies and warm southerly winds. Recent observations confirm a warming trend, with March 20-21 highs reaching 26-27°C amid low humidity and high solar insolation typical of the region's subtropical spring climate. Probabilities taper for 28°C (18.6%) and higher due to potential afternoon sea breeze moderation and a weak frontal boundary hinted in GFS updates, while sub-27°C outcomes (<1%) reflect historical March averages around 25°C exceeded by current anomalous warmth linked to lingering El Niño influences. Key watch: Evening model refreshes could shift odds if cloud cover builds.
