Trader consensus strongly favors a high of 29°C or higher in Shenzhen on March 20 at 87% implied probability, driven by the latest forecasts from the China Meteorological Administration and ECMWF models projecting peaks near 31°C amid a persistent high-pressure ridge and southerly winds advecting warm, humid air from the South China Sea. Shenzhen's humid subtropical climate typically sees March highs averaging 24-26°C, but this year's early spring heat surge—fueled by weakening La Niña transition—has pushed recent days into the upper 20s to low 30s, with airport observations yesterday hitting 29.5°C. Lower outcomes like 28°C (1.7%) reflect minor model spread, while sub-25°C odds near zero align with negligible cool-front risks per GFS ensembles. Traders eye afternoon updates for final conviction.
