Recent forecast guidance from the China Meteorological Administration and ECMWF ensembles indicates persistent cloud cover and scattered showers across the Pearl River Delta on May 17, moderating daytime heating and anchoring the most likely high near 27°C. Elevated humidity near 80 percent combined with light southerly flow from the South China Sea further limits maximum temperatures below the mid-May climatological average of 29–30°C. These conditions create a tight distribution among the 26°C, 27°C, and 28°C outcomes, with traders weighting the balance between partial clearing that could allow brief warming versus sustained moisture that would cap readings. Official Shenzhen station data from the CMA will determine resolution once available.
