**Current conditions and official observations from the Hong Kong Observatory position 27°C as the dominant outcome.** As of late afternoon on September 13, 2026, the minimum air temperature recorded since midnight at the Observatory stood at 27.7°C, with other stations ranging from 25.2°C to 27.7°C. Forecast models consistently project overnight lows near 26–27°C amid partly cloudy skies, high humidity near 80–95%, light easterly winds, and scattered thunderstorms that limit radiative cooling. These factors align with historical September norms for the region and explain the market’s strong 87% implied probability for 27°C, while lower outcomes like 26°C or 25°C remain possible only if clearer skies allow further overnight drops not currently indicated by guidance.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 13 Sep '26.
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.**Current conditions and official observations from the Hong Kong Observatory position 27°C as the dominant outcome.** As of late afternoon on September 13, 2026, the minimum air temperature recorded since midnight at the Observatory stood at 27.7°C, with other stations ranging from 25.2°C to 27.7°C.
