Forecast models and Hong Kong Observatory guidance point to minimum temperatures near 27°C on September 5, consistent with the market's 97.5% implied probability for that outcome. September climatology shows typical daily lows of 24–26°C, but recent observations and short-range forecasts indicate stable subtropical conditions with overnight readings holding around 26–27°C amid partly cloudy skies and light winds. Official data distinguish verified measurements from projections, and the narrow range of outcomes reflects limited model spread for this period. A stronger-than-expected cold front or enhanced cloud cover could lower readings toward 25°C, though current steering patterns and humidity levels make such shifts unlikely before 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
In the event that there is no data for the observation date by 11:59 PM ET on the seventh day following the observation date, this market will resolve to the lowest bracket.
This market will resolve once data for this date has been published on the resolution source, or by 11:59 PM ET on the seventh day following the observation date, whichever comes first.
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.
