**Persistent unsettled weather from a broad trough of low pressure over the South China Sea continues to drive trader consensus toward 25°C as the most probable minimum temperature in Hong Kong on August 4.** Official Hong Kong Observatory guidance currently forecasts a daily range of 25–30°C under mostly cloudy to rainy conditions with 70–95% relative humidity. Numerical model consensus and recent observations show frequent showers and thunderstorms suppressing daytime heating while limiting nocturnal radiative cooling, keeping overnight lows near the lower end of the seasonal envelope. August climatological averages hover around 27°C for minima, but the active monsoon trough and southeasterly flow are producing a cooler, more stable regime. No typhoon or strong anticyclonic influence is expected to alter this pattern before resolution. The developing El Niño backdrop favors normal-to-above-normal temperatures seasonally, yet short-term synoptic controls dominate the two-day outlook. Updated HKO briefings and model runs over the next 24–48 hours represent the key data points that could shift implied probabilities.
