A broad trough of low pressure persisting over southern China is driving unsettled conditions and elevated thunderstorm activity across Hong Kong, producing the market's dispersed odds between 23–29°C minima. Official Hong Kong Observatory guidance for August 25 projects a 26–29°C range under south to southwesterly winds of force 4–6, with heavy showers expected to enhance nocturnal cooling through cloud cover and evaporative effects. Ensemble model outputs and recent runs show modest spread in overnight lows around 25–27°C, consistent with typical late-August climatology near 27°C but sensitive to exact timing of convective outbreaks. Traders are weighting both the official forecast and potential for localized cooling below 26°C ahead of the next model updates and any shifts in regional steering patterns.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Min (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.
