Recent official forecasts from the Hong Kong Observatory and models indicate overnight lows near 25–26°C for July 30 amid typical summer monsoon flow and scattered showers, keeping skies mostly cloudy and limiting radiational cooling. These conditions, combined with above-normal seasonal temperatures and high humidity, support the near-even trader split between the two leading outcomes. Key variables include exact rain timing, which could trap heat and push the minimum higher, versus clearer intervals allowing brief dips; updated model runs over the next 48 hours will likely refine this range before resolution.
