Trader sentiment for Shenzhen’s highest temperature on May 18 centers on the latest China Meteorological Administration model runs projecting a peak near 29 °C under a stable subtropical high-pressure ridge. This setup favors modest onshore flow and limited afternoon convection, keeping daytime maxima in the upper 20s while seasonal climatology for mid-May in the Pearl River Delta places average highs around 29–31 °C. Small spreads across 28 °C and 27 °C outcomes reflect residual uncertainty in cloud cover timing and urban heat-island amplification, both of which can shift the daily maximum by 1–2 °C. New model guidance and observational updates expected overnight will further refine these probabilities before resolution.
