Official Hong Kong Observatory measurements recorded a minimum air temperature of 26°C on September 4, 2026, aligning with the market's near-certain 99.8% implied probability for that outcome. Persistent warm, humid maritime air under mostly cloudy skies limited nocturnal radiative cooling, while urban heat island effects in the densely built environment further moderated overnight lows. This aligns with climatological norms for early September, when average daily minima hover near 24–26°C amid the lingering influence of the East Asian summer monsoon. Forecasters note that only an atypical surge of drier, clearer air or stronger northerly winds could have driven readings below 24°C, conditions absent in the verified observations.

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.
