Official forecasts from the Hong Kong Observatory indicate mainly cloudy conditions with occasional showers and squally thunderstorms on August 31, driven by a broad low-pressure trough over the South China Sea, which favors cloud cover and reduced solar heating that typically caps daytime maxima near 30°C. Recent observations show highs of 32–33°C on August 29 amid lighter winds and partial sunshine, with models pointing to increased rainfall probability and a wind shift that could further moderate temperatures through enhanced mixing and evaporative cooling. Thunderstorm timing and intensity introduce variability in peak readings across stations, explaining the market's tight clustering between 29–30°C alongside residual probability on hotter outcomes if convection remains limited. Updated HKO guidance and regional model runs will refine these thresholds ahead of resolution.
