Official forecasts from the Hong Kong Observatory project a minimum temperature of 27°C on September 21, with a daily range of 27–32°C under light northeasterly winds of 2–3 on the Beaufort scale, high humidity of 65–95%, and scattered showers or thunderstorms. These conditions limit nocturnal radiative cooling typical in late summer, as weak pressure gradients and moisture from upstream disturbances maintain warmth overnight. Multiple numerical models align on this baseline, with no strong cold advection or clear-sky radiative loss expected to push readings lower. Trader consensus at 72.5% for 27°C reflects this model agreement and historical September minima near 27°C, while lower-probability outcomes hinge on any forecast revisions from updated HKO briefings or unexpected intensification of showers.

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.
