Latest GFS, ECMWF, and China Meteorological Administration ensemble forecasts converge on a high temperature near 26°C for Shenzhen on April 4, anchoring trader sentiment with 27% implied probability on that outcome amid neck-and-neck competition from 25°C (20%) and 24°C (18%). Persistent southerly winds and high humidity fuel convective showers and cloud cover, capping solar insolation and differentiating lower outcomes, while brief clear intervals could push toward 27°C. Historical early-April highs average 25°C, but current subtropical ridge positioning supports mild above-normal warmth. Inherent short-range forecast uncertainty from precipitation timing persists; watch CMA's April 3 update and afternoon Bao'an International Airport observations for resolution.
