This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 4 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 data and forecasts underpin the market's 99.1% implied probability for a 26°C high on April 4, with current observations at King's Park and HKO headquarters showing peak temperatures near 26-27°C earlier today amid a trough of low pressure bringing cloudy skies, showers, and 85-90% relative humidity that cap solar heating. Seasonal outlooks predict above-normal April temperatures, consistent with March's unseasonably warm 24.5°C mean maximum, but persistent rain and moderate southerly winds limit intensification. Realistic challenges include unexpected afternoon clearing for a 27°C+ push or heavier squally thunderstorms cooling to 25°C or below; resolution awaits official end-of-day King's Park measurement.
