This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 25 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 maximum air temperature of 26°C at its headquarters on April 25, 2026, under mainly fine conditions with moderate easterly winds, driving trader consensus to 100% on this outcome as the market nears resolution. This aligns with April climatological norms, where the mean maximum temperature averages around 25.5°C amid subtropical high-pressure influence, while regional automatic stations recorded higher peaks up to 30.2°C in outlying areas like Yuen Long Park. The positioning reflects verified hourly readings from HKO's standard measurement protocols at King's Park. Realistic challenges would require an official data audit revealing measurement errors or overlooked peaks, though such revisions are exceedingly rare in established meteorological records.
