Forecast models from the Hong Kong Observatory and global ensembles point to a daytime maximum of 32–34°C on August 13 as the dominant outcome, with trader-implied probabilities heavily concentrated there (32°C at 31%, 33°C at 41%, 34°C at 19.5%). Persistent subtropical high pressure and above-normal seasonal temperatures—consistent with the Observatory’s August–October outlook for normal-to-above-normal readings—support this range, while scattered showers and cloud cover are expected to cap extreme peaks near 35°C or higher. Recent very-hot-weather warnings and minimal recent cooling from tropical systems reinforce the market’s tight clustering around the long-term August average of ~32°C, with only low-probability outcomes assigned to outliers below 31°C or above 35°C.
