Recent forecasts from the Hong Kong Observatory and models indicate a high near 32–33°C on August 16 amid thundery showers and 70–90% rain probability, which explains the tight market split between those two outcomes. Persistent cloud cover and precipitation from a southwesterly airstream limit daytime heating and surface insolation, while high humidity near 80% further moderates maximum temperatures through evaporative cooling. Recent extremely hot conditions tied to Tropical Cyclone Dolphin have given way to this more typical August pattern of scattered convection, reducing the chance of exceeding 34°C. Traders weigh the latest multi-model consensus and timing of any rain bands against historical August maxima around 31–32°C when assessing whether isolated breaks in cloud could push the official reading to 33°C.
