Official observations from the Hong Kong Observatory recorded a minimum air temperature of 28°C on August 28, 2026, driving the market's overwhelming 99.9% implied probability for that outcome. Persistent cloud cover, moderate humidity above 80%, and scattered rainfall limited radiative cooling overnight, keeping overnight lows elevated in line with typical late-summer subtropical conditions. This aligns with regional model guidance and station data showing temperatures holding near or above 28°C through the early morning hours. Only an unanticipated data revision from the primary reference station or a shift in resolution criteria could alter the result, though current evidence indicates strong consensus around the observed minimum.

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.
