**Cloud cover, showers, and elevated humidity from a broad low-pressure trough combined with lingering tropical cyclone influences are suppressing peak temperatures across Hong Kong on September 1.** Official Hong Kong Observatory forecasts and regional observations indicate daytime maxima most likely between 28–30 °C under mostly cloudy skies, with northerly winds of 4–5 Beaufort and a high probability of thunderstorms. These conditions limit solar insolation and enhance evaporative cooling, keeping readings below the early-September climatological average of ~31 °C. Early-morning station data near 27 °C and model consensus for limited afternoon warming reinforce trader emphasis on the 28–29 °C outcomes, while the modest probability assigned to 30 °C reflects residual uncertainty in exactly how much brief sunshine may develop before widespread convection. The market-implied distribution therefore aligns closely with current atmospheric conditions and the latest authoritative guidance.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (deg. C)" the specified date once information is finalized in the relevant "Daily Extract", available here: https://www.weather.gov.hk/en/cis/climat.htm
This market can not resolve until data for this date has been published.
The resolution source for this market measures temperatures in Celsius to one decimal place (eg, 9.1°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is initially published for this market's timeframe will not be considered for this market's resolution.
