This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 30 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 until data for this date has been published. 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 initially published for this market's timeframe will not be considered for this market's resolution.The market-implied 100% odds on 32°C as Hong Kong’s highest temperature on May 30 stem directly from official Hong Kong Observatory measurements confirming that daily maximum. Persistent very hot weather conditions, driven by regional atmospheric patterns and elevated humidity, aligned with model forecasts projecting a peak near this threshold rather than the seasonal average of roughly 28–29°C. Recent data releases from monitoring agencies reinforced this outcome with no significant downward revisions, while cooler monsoon influences remained too weak to alter the result. Minor scenarios such as localized measurement adjustments or unverified microclimate effects could theoretically shift the recorded value, but current observational consensus leaves little room for deviation.
