**Trader consensus strongly favors a 27°C minimum in Hong Kong on September 12, 2026, at 99.5% implied probability, reflecting persistent northeast monsoon conditions and typical late-summer humidity that limit overnight radiative cooling.** Official Hong Kong Observatory observations and regional forecasts show nighttime temperatures holding between 26–28°C amid cloudy skies, scattered showers, and dew points near 25–26°C, consistent with climatological September averages. Model consensus across sources points to a floor near 26–27°C rather than sharper drops, as cloud cover and moisture suppress temperature falls. A realistic challenge would require unexpected clear skies or stronger offshore flow enabling greater cooling below 26°C, though current steering patterns and sea-surface temperatures around 28°C make significant deviation 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.
