This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 15 May '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.Official observations from the Hong Kong Observatory confirmed a daily maximum temperature of 27°C on May 15, driven by typical late-spring subtropical conditions with light southerly winds and minimal cloud cover allowing strong solar heating. This outcome aligns with climatological averages for the period and matches real-time sensor data across urban and airport stations, leaving virtually no uncertainty in market resolution. Traders placed near-certain odds on 27°C because alternative thresholds would have required atypical cooling from unforecasted frontal systems or persistent rain, none of which materialized in the final 24-hour analysis.
