The Hong Kong Observatory's official forecast for September 17 calls for a maximum of 32°C under fine, dry conditions with east winds of force 4 to 5, sustained by a fresh northeast monsoon and upper-level anticyclone that have maintained stable, clear weather across the region. This places the expected high near the upper end of the typical mid-September climatological range of 30–31°C, where model consensus shows limited variability absent tropical moisture or frontal systems. Trader emphasis on 31–32°C outcomes reflects the narrow uncertainty band in the current guidance, with resolution hinging on the Observatory's official daily maximum measurement; any late-model shift toward slightly cooler advection could tilt probabilities modestly lower before the 24-hour window closes.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 17 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.
