Traders assign the highest probabilities to a maximum of 34–36°C on August 11 because official guidance and ensemble forecasts from the Hong Kong Observatory point to daytime highs in the mid-30s under typical late-summer conditions of high humidity, weak winds, and variable cloud cover. Normal-to-above-normal seasonal temperatures, driven by background climate warming and current ENSO-neutral patterns, set the baseline, while day-to-day differences in solar insolation and urban heat retention determine whether the peak reaches 35°C or edges higher or lower. Model spread and the possibility of increased afternoon convection introduce the observed uncertainty between the closely matched outcomes, with resolution hinging on the final verified reading at the official observatory site.
