This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 18 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 (HKO) observations confirm a highest temperature of 28°C across monitoring stations on April 18, driving trader consensus to 100% implied probability for this outcome as the definitive market resolution criterion. This aligns with subtropical climatological norms for mid-April, where maximums typically range 25–29°C amid normal to above-normal seasonal temperatures per HKO's April–June 2026 forecast, influenced by continental air flows and minimal cloud cover that day. Verified surface measurements from the Observatory and regional sites provide unassailable evidence, with data releases in the past 48 hours solidifying positioning. Realistic challenges are negligible—only a formal data audit uncovering overlooked station peaks could shift it, an exceedingly rare occurrence.
