This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 23 Sep '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 In the event that there is no data for the observation date by 11:59 PM ET on the seventh day following the observation date, this market will resolve to the lowest bracket. This market will resolve once data for this date has been published on the resolution source, or by 11:59 PM ET on the seventh day following the observation date, whichever comes first. 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 forecasts from the Hong Kong Observatory indicate a maximum of 31°C on September 23 under persistent northeast monsoon influence, with easterly winds at force 4, sunny periods, and isolated showers. These conditions—moderate onshore flow from the South China Sea and limited insolation from cloud cover—favor a peak near 31°C rather than higher values that would require stronger subsidence or clearer skies. Recent model consensus aligns with this range, consistent with late-September climatology after peak summer heating. Trader emphasis on 31°C (42.5% implied probability) and nearby 30–32°C outcomes reflects this stable forecast signal ahead of final observational confirmation.
