Official forecasts from the Hong Kong Observatory project a daily minimum near 28°C on August 23, 2026, under late-summer monsoon trough conditions featuring southwest winds, 70–90% relative humidity, scattered showers, and isolated thunderstorms that limit radiative cooling overnight. This aligns with climatological August overnight lows of 26–28°C at the Observatory headquarters and recent station readings showing early-morning values around 28°C. Numerical model consensus reinforces this narrow range, with minimal potential for sharper drops absent atypical continental air intrusion. A sudden intensification of convection or measurement revision below 27.5°C remains the primary low-probability scenario that could shift resolution.

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.
