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 9-day forecast, updated at 7:50 a.m. HKT on April 5, projects a maximum temperature of 27°C with minimums around 23°C amid mainly cloudy conditions, occasional showers, and isolated squally thunderstorms, driving trader sentiment toward 26°C (38.5% implied probability), 25°C (28.5%), and 27°C (25.5%). This aligns with yesterday's observed peak of 26.4°C at the Observatory station and a slight cooling trend under southeasterly winds force 3-5 bringing moist air, high humidity (75-95%), and heavy precipitation risk that limits solar heating. April's above-normal temperature outlook provides context, but shower timing introduces uncertainty; current 9 a.m. readings of 24°C and 92% relative humidity underscore potential for mid-20s peaks, with hourly updates and afternoon developments key ahead of official daily resolution.
