This market will resolve to the temperature range that contains the highest 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 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 observations confirm the highest air temperature on May 13, 2026, reached 34.6°C at Sheung Shui station, with other sites like Tai Lung and Ta Kwu Ling exceeding 33°C, driving trader consensus to 100% implied probability for 31°C or higher. Sunny skies, low humidity, and a ridge of high pressure fostered intense afternoon heating typical of May's transition to summer, aligning with seasonal forecasts for above-normal temperatures amid ongoing climate warming trends in the region. While official measurements from multiple verified stations provide robust evidence, rare scenarios like data revisions from equipment recalibration or post-audit discrepancies could theoretically challenge this positioning, though such events are exceedingly uncommon.
