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 April 3, projects a maximum temperature of 27°C on April 5 amid a lingering trough of low pressure over southern China, bringing mainly cloudy skies, occasional showers, and isolated squally thunderstorms that temper daytime heating. Trader consensus closely splits between 27°C (38.5%) and 26°C (33%), reflecting short-term forecast uncertainty in cloud cover persistence, shower timing, and southerly winds strengthening to force 5, which could either allow brief peaks near 27°C or suppress them under heavier precipitation. This aligns with above-normal April temperatures and recent highs of 24–28°C; watch HKO's daily updates for trough evolution.
