Traders price 30–31°C as the most probable peak for Hong Kong on August 25 because numerical models and Hong Kong Observatory guidance show persistent monsoon-trough conditions with southwest flow, 70–90% relative humidity, and scattered showers or thunderstorms. These factors limit surface solar heating and cap maximum temperatures near the long-term August average of roughly 31°C. Recent runs indicate modest variability tied to the exact timing and coverage of convection: clearer intervals could allow brief climbs to 32°C, while heavier rain would favor 29°C. Seasonal outlooks note normal-to-above-normal temperatures overall, yet short-range uncertainty in cloud and precipitation fields keeps the 29–32°C band tightly contested ahead of final observational data.
