**Current forecasts from the Hong Kong Observatory and regional models indicate a minimum near 25°C overnight on September 6, 2026, driven by persistent cloud cover, scattered showers, and high humidity that limit radiative cooling.** In Hong Kong’s subtropical September climate, typical overnight lows hover between 25–27°C due to warm sea surface temperatures in the northern South China Sea and urban heat retention. Recent observations show overnight readings stabilizing around 26°C with dew points near 24–25°C, supporting the market-implied 98.5% consensus on 25°C as the official daily minimum. Key upcoming data include the HKO’s final hourly readings and daily extract, which will confirm the absolute low. A realistic challenge would require clearer skies or stronger offshore flow enabling greater nocturnal cooling to 24°C, though current steering patterns and moisture make this unlikely.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 6 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 forecasts from the Hong Kong Observatory and regional models indicate a minimum near 25°C overnight on September 6, 2026, driven by persistent cloud cover, scattered showers, and high humidity that limit radiative cooling.**
