This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 22 Aug '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 This market can not resolve until data for this date has been published. 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.Persistent cloud cover and scattered showers associated with a broad low-pressure trough over the northern South China Sea suppressed solar heating across Hong Kong on August 22, 2026, producing an official Hong Kong Observatory maximum of 31.8 °C at the central station. High humidity levels of 70–95 % combined with southwesterly flow further limited afternoon warming, keeping readings within the 31 °C band despite regional spikes to 33.6 °C at exposed sites. This observational record from the Hong Kong Observatory underpins the near-100 % market-implied odds on 31 °C. Late revisions to finalized daily data or differing interpretations of regional versus headquarters readings remain the only realistic scenarios that could alter resolution.
