Recent official forecasts for Guangzhou on August 29 show daily maximum temperatures clustered around 34–36 °C, with model runs indicating partly cloudy skies, light northwest winds, and a 40–80 % chance of scattered showers that could suppress peak readings. Subtropical summer conditions in the Pearl River Delta—high humidity, weak steering flow, and variable convective activity—create narrow uncertainty bands between 35 °C and 37 °C, as afternoon cloud build-up or brief rain episodes often cap temperatures 1–2 °C below clear-sky potential. Trader consensus at 36–37 °C reflects the balance between climatological August averages near 33 °C and the current ensemble spread favoring slightly above-normal readings if convection remains limited. Updated model guidance and local observations on the 28th will be the key near-term catalyst.
