This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 3 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 official observations confirm the highest air temperature reached 27.1°C at the King’s Park station on April 3, 2026, driving trader consensus to a 99.9% implied probability for the 27°C outcome amid showers and thunderstorms from a nearby low-pressure trough. This aligns with automated weather station data across the territory, where maximums hovered near seasonal norms of around 26°C for April, bolstered by the seasonal forecast of normal to above-normal temperatures under lingering El Niño influences. Realistic challenges to resolution are minimal—only an instrument malfunction or rare data audit could prompt revision, as preliminary reports match real-time regional readings peaking in the mid-27s before evening cooling.
