This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 5 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 latest 9-day forecast, updated at 11:15 HKT on April 5, projects daytime highs of 23–27°C amid mainly cloudy skies, heavy showers, and squally thunderstorms driven by a trough of low pressure over Guangdong's coast, fostering high relative humidity (75–95%) that curbs solar heating and atmospheric warming. Current observations at 11:11 HKT show air temperatures of 22–25°C across key stations like Yuen Long Park and Lau Fau Shan, with the Hong Kong Observatory at 23°C under moderate southeasterly winds. This setup aligns trader consensus at 48% implied probability for 25°C and 29.5% for 26°C, consistent with April's above-normal temperature outlook and yesterday's 26°C peak, though persistent cloud cover introduces uncertainty—new hourly updates and afternoon conditions could shift outcomes toward 24°C (20%) if showers intensify.
