Recent ensemble forecasts from the ECMWF and GFS models show Shanghai’s May 18 maximum temperature most likely settling near 26–27°C under a mix of partly cloudy skies and light southerly flow that moderates daytime heating. This narrow spread aligns with mid-May climatology, where historical observations from the China Meteorological Administration record average daily highs between 24°C and 26°C, yet subtle differences in low-level moisture and boundary-layer mixing can easily shift the peak by one degree. Trader-implied odds cluster tightly around these outcomes because further model runs expected overnight and the official China Meteorological Administration afternoon guidance will clarify whether increased cloud cover or a brief ridge of high pressure pushes readings toward 28°C or holds them at 26°C.
