This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 13 May '26. The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Min (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.The Hong Kong Observatory (HKO) recorded a minimum air temperature of 26.2°C on May 13, 2026—the lowest of the day—driving trader consensus to 100% implied probability on the 26°C outcome in this resolved market. This observation, captured via standard meteorological instruments from midnight through the full diurnal cycle, aligns with pre-event forecasts anticipating limited overnight cooling amid persistent humidity and scattered clouds, consistent with May climatology where average lows hover around 24–25°C but warmer anomalies prevail in 2026's record-hot year. Scenarios challenging this positioning are negligible, requiring an unprecedented HKO data revision due to instrumental malfunction, as verified readings represent authoritative ground truth with no further updates expected.
