Recent forecasts from multiple models indicate moderating maximum temperatures in Guangzhou on September 22 due to increased cloud cover, scattered thunderstorms, and moist southerly flow associated with regional monsoon patterns, which limit daytime heating compared to clearer conditions earlier in the week. Official guidance points to highs near 31–34°C, with precipitation probabilities of 50–80% potentially suppressing peaks below recent 35–37°C readings. Trader sentiment clusters around 34–35°C outcomes because model runs show variability in storm timing and intensity, while historical September baselines near 30–31°C provide context for upside potential if convection remains limited. Updated model outputs and local observations over the next 48 hours will likely refine these probabilities.
