This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 8 May '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 (HKO) observations confirm the highest air temperature on May 8, 2026, reached exactly 30°C at multiple automatic weather stations, driving trader consensus to a 100% implied probability on this outcome as the market nears resolution. This peak aligns with sunny conditions under a subtropical anticyclone ridge, fostering above-normal daytime heating typical for early May, when climatological mean maxima hover around 28.5°C. Real-time hourly readings showed morning temperatures near 25°C at the Observatory rising steadily amid low humidity and light winds. Realistic challenges are negligible, limited to rare post-validation data revisions from sensor anomalies, as HKO employs rigorous quality controls on shaded-screen measurements for authoritative finality.
