Northeast monsoon winds are the dominant factor shaping overnight cooling for Hong Kong on September 11, with official Hong Kong Observatory guidance forecasting a minimum of 25–26°C under mainly fine conditions and north to northeast flow of force 4–5. Clear to partly cloudy skies overnight support modest radiative cooling, while moderate humidity (50–85%) limits further drops below the seasonal norm near 26°C. Recent model consensus and real-time observations show limited variability, keeping 26°C as the market leader at 42% implied probability, followed closely by 25°C. Updated forecast briefings or any shift in wind strength could refine the exact minimum 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.
