This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 23 Apr '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 to "Yes" until data for this date has been finalized. 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 finalized for this market's timeframe will not be considered for this market's resolution.Hong Kong Observatory's official observational data confirms the highest temperature on April 23, 2026, reached 29°C at the King's Park station, locking in trader consensus at 100% implied probability for this outcome amid thin liquidity in alternatives. This aligns with above-normal seasonal temperatures forecasted for April-June, driven by persistent subtropical high pressure and light winds fostering daytime heating, consistent with April climatology where maxima often exceed 28°C during warm spells. Real-time readings from multiple stations, including urban heat effects, supported the rapid shift from pre-day leads like 27°C. Post-verification challenges are minimal, though rare data revisions from quality control or equipment anomalies could theoretically prompt adjustments before final resolution.
