Recent model consensus from the Hong Kong Observatory and global ensembles points to a minimum temperature of 26–27°C on August 18, driven by persistent high humidity, light winds, and partial cloud cover from scattered showers that limit nocturnal radiative cooling in the subtropical urban environment. Typical August climatology features overnight lows near 26–28°C due to the Pearl River Delta's marine influence and urban heat island effects, with showers further moderating temperature drops by enhancing downward longwave radiation. Slight probability edges for 26°C versus 27°C hinge on forecast details such as cloud thickness, boundary-layer moisture, and any localized thunderstorm timing, which can alter cooling rates by 1–2°C. Updated runs from multi-model systems and the next HKO briefing will refine these thresholds ahead of 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.
