Latest global forecast models, including runs from the China Meteorological Administration and ECMWF, project Shanghai overnight lows near 19–21 °C on May 24, positioning these outcomes as market leaders. This aligns with mid-to-late May climatology, where historical minima average 17–20 °C under the influence of a strengthening subtropical high that limits cold-air advection and allows moderating sea breezes. No significant frontal passages or northerly surges appear in current synoptic analyses, keeping probabilities for sub-18 °C readings low. Traders are monitoring the next 48-hour model updates for any shifts in boundary-layer moisture or wind patterns that could alter the minimum by 1–2 °C.
