Hong Kong Observatory's official measurements at the King's Park reference station confirm the highest temperature on April 30, 2026, reached 26.7°C, driving trader consensus to 100% on the 25°C or higher outcome as the market nears resolution. This observational data, recorded under clear skies amid an exceptionally warm April—marked by above-normal temperatures and abundant sunshine—solidifies the positioning, aligning with seasonal norms where late-April highs often exceed 25°C due to strengthening subtropical high pressure. While forecast models had anticipated mild conditions, the verified reading leaves negligible uncertainty; only an unprecedented data revision by HKO could challenge it, though such corrections are rare for established records. Traders await the final monthly weather summary for archival confirmation.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 30 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.
