The market's near-certain positioning on 31°C as Hong Kong's highest temperature for September 17, 2026, reflects official Hong Kong Observatory measurements showing an absolute daily maximum of 31.4°C under partly cloudy skies with light easterly winds. This aligns with typical mid-September climatology, where mean highs hover near 30–31°C amid weakening summer monsoon influences and moderate humidity around 70%. No significant frontal systems or heavy rainfall altered the diurnal heating cycle that day, keeping peak values within the narrow 31°C band rather than pushing toward higher thresholds. Updated surface observations and model consensus on stable steering patterns reinforced this outcome ahead of final verification.

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.
Any revisions to temperatures recorded after data is initially published for this market's timeframe will not be considered for this market's resolution.The market's near-certain positioning on 31°C as Hong Kong's highest temperature for September 17, 2026, reflects official Hong Kong Observatory measurements showing an absolute daily maximum of 31.4°C under partly cloudy skies with light easterly winds.
