Traders assign an 88% implied probability to a 27°C low in Hong Kong on September 21 because official Hong Kong Observatory readings show minimum temperatures since midnight clustered around 26–27.8°C across urban and airport stations, with little overnight cooling. Persistent high humidity near 70–90%, light winds, and partial cloud cover have limited radiative heat loss under typical late-summer conditions. Recent model guidance and climatological norms for mid-September support a narrow range near 26–28°C rather than cooler outcomes, as no cold surge or clear-sky radiative event has materialized. Updated forecasts through the evening will determine whether any brief dip below 27°C occurs before midnight.

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.
