This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 18 Aug '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.Official Hong Kong Observatory data confirmed a daily maximum of 32°C on August 18, aligning with regional forecast models showing highs in the 28–33°C range amid typical summer conditions. This matches long-term August climatology, where average maxima hover near 32°C, and recent subsidence or light wind patterns supported stable heat without significant cooling from rainfall or cloud cover. Traders' 100% consensus reflects verified observational records rather than projections, with the market resolving on the Observatory's headquarters reading as the authoritative benchmark. Unlikely challenges include post-publication data corrections from sensor issues or alternative station maxima exceeding the threshold, though historical consistency makes such revisions rare.
