Hong Kong Observatory forecasts a minimum of 27°C for September 7, with a daytime range of 27–32°C under light winds and partly cloudy conditions with isolated showers. Real-time observations from the agency’s network confirm overnight readings holding near 27°C, consistent with typical early-September climatology and the absence of stronger cooling influences like enhanced monsoon flow or organized convection. This alignment drives the market’s 99% implied probability for exactly 27°C. A notable downward revision in the final official minimum would require unexpected heavy nocturnal rainfall or a sharper-than-anticipated drop in dew points, though current steering patterns and model guidance make such shifts improbable before resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 7 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.Hong Kong Observatory forecasts a minimum of 27°C for September 7, with a daytime range of 27–32°C under light winds and partly cloudy conditions with isolated showers.
