Recent forecast guidance from the Hong Kong Observatory and global models indicates a highest temperature on September 2 most likely in the 29–31 °C range, driven by north to northwest winds of 4–6 on the Beaufort scale that advect slightly drier continental air while a lingering low-pressure trough over the northern South China Sea maintains variable cloud cover and scattered showers. These conditions limit daytime heating compared with clearer anticyclonic setups typical in early September, when climatological maximums average near 30.5 °C. Model spread in timing and intensity of showers creates the tight market clustering around 29–30 °C, with any break in cloud allowing brief peaks near 31 °C. Updated regional model runs and the next HKO briefing will refine land–sea breeze and precipitation timing ahead of market resolution.
