Official forecasts from the Hong Kong Observatory and global models indicate a northeast monsoon regime bringing mostly fine to partly cloudy skies and light easterly winds for September 25, supporting maximum temperatures near 31–32 °C. Recent model runs show limited diurnal heating due to moderate humidity around 65–85 % and minimal precipitation risk below 10 %, keeping extremes unlikely. Slight differences among ensembles arise from variable cloud timing and boundary-layer mixing, which could nudge the daily high by 1 °C in either direction. With resolution hinging on the official HKO maximum reading, traders are weighting the narrow 30–33 °C band most heavily ahead of the next model update.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 25 Sep '26.
The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (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.Official forecasts from the Hong Kong Observatory and global models indicate a northeast monsoon regime bringing mostly fine to partly cloudy skies and light easterly winds for September 25, supporting maximum temperatures near 31–32 °C.
