Highest temperature in Hong Kong on August 3?

Platform comparison

Market context

Hong Kong’s highest temperature on 3 August will be set by the Hong Kong Observatory’s final daily extract, so the live number to watch is the day’s “Absolute Daily Max (deg. C)” rather than any headline forecast. Early market pricing is clustered around the upper-20s Celsius, with the current book leaning most heavily towards 27°C and 28°C, which reflects a fairly standard August summer range rather than an outlier heat spike.[7][11]

That positioning is consistent with broader seasonal data. Multiple forecast services put early-August Hong Kong highs in the high-20s to low-30s Celsius, but they also flag frequent showers, high humidity and cloud cover, all of which tend to cap the daytime maximum rather than allow a clean run towards the low-30s.[1][2][5][12][18] In recent updates, Polymarket’s own market commentary has said persistent showers and extensive cloud cover are suppressing maximum temperatures and concentrating odds around 27–28°C.[7]

For traders, the main catalysts are the Hong Kong Observatory’s short-range forecast updates, any rain or thunderstorm warnings, and whether the city stays under prolonged cloud and onshore flow through the daytime period.[11][14][16] Because the market only resolves once the final daily data is published, late adjustments to the official extract matter more than intraday anecdotes, while any tropical disturbance or locally heavier rain would mainly help the lower-temperature bands by limiting solar heating.[7][16][17]
