Latest ensemble forecasts from global models indicate Shanghai's daily maximum on May 18 will likely settle near 26–27 °C under moderate southerly flow and variable cloud cover typical of the East Asian monsoon transition. Subtropical spring conditions, including sea-surface temperatures around 20 °C in the East China Sea and limited upper-level ridging, constrain stronger warming while suppressing the risk of cooler northerly intrusions. Historical mid-May climatology for the city centers on 25 °C highs, so traders are weighting current guidance against small uncertainties in boundary-layer moisture and diurnal heating rates. Updated runs from the ECMWF and GFS over the next 24 hours will clarify whether modest clearing pushes the peak toward 28 °C or persistent stratus caps it at 26 °C.
