Persistent monsoon trough activity and the nearby influence of Tropical Cyclone Purple Sand are driving widespread cloud cover, scattered thunderstorms, and southerly flow over Hong Kong on August 26, limiting surface heating and keeping official Hong Kong Observatory forecasts centered on a maximum of 29–31 °C. High boundary-layer humidity and frequent convective showers further cap afternoon peaks by enhancing evaporative cooling and reducing insolation, with ensemble guidance showing only modest spread around these values. The near-even market split between 30 °C and 31 °C reflects uncertainty in the precise timing and intensity of rain bands, which can shift the daily maximum by 1–2 °C depending on whether clearer intervals allow brief warming before renewed convection. Resolution will hinge on the Hong Kong Observatory’s verified daily maximum recorded at the King’s Park or Observatory headquarters stations.

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.
