Recent numerical weather predictions from the Hong Kong Observatory and global models indicate partly cloudy to showery conditions on August 4 that are likely to cap daytime heating near 29–31 °C, keeping the market-implied odds tightly clustered between 30 °C (39.5 %) and 29 °C (32.5 %). Persistent moisture and cloud cover reduce surface insolation while southeasterly flow limits extreme warming, consistent with August climatology of mean highs near 31 °C yet tempered by above-normal rainfall probabilities. Minor differences in boundary-layer mixing and timing of convective showers across ensemble members create the narrow spread separating these outcomes. Updated HKO guidance and afternoon model runs expected over the next 24 hours will further refine the maximum-temperature distribution ahead of market resolution.
