Official forecasts from the Hong Kong Observatory indicate a Monday minimum of 27°C under mainly cloudy skies with a few showers and isolated thunderstorms, driven by a weakening anticyclone and the early influence of a northeast monsoon flow. Ensemble model guidance and nearby stations show overnight lows holding in the 26–28°C range, with high humidity near 90% and light variable winds limiting radiative cooling. This aligns with typical late-September climatology for the region, where daily minima rarely drop below 26°C absent stronger frontal passages or heavy rain. No significant model divergences or tropical system impacts appear in the short-range guidance ahead of the September 21 observation window, supporting the market’s emphasis on 27°C as the consensus outcome.

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.
