Recent forecast guidance from the China Meteorological Administration highlights a strengthening subtropical high over the Pearl River Delta, positioning Shenzhen for daily maximum temperatures of 28–30°C on May 19 amid moderate humidity and partial cloud cover. Regional model consensus, including European Centre and Global Forecast System runs, shows limited onshore flow suppressing stronger heating while allowing peaks in the upper 20s Celsius, consistent with mid-May climatology where historical station data cluster around 29°C. Trader sentiment reflects this narrow range of outcomes, with upcoming model updates and official briefings likely to clarify any shifts from evolving moisture patterns or wind steering.
