This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 2 Sep '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 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 measurements recorded a minimum air temperature of 25°C on September 2, 2026, aligning with the market's near-certain 25°C outcome. Persistent cloud cover, light rain showers, and moderate northwest winds limited nighttime radiative cooling, keeping overnight lows near the seasonal average for early September rather than allowing dips toward 24°C. Forecasters from the Hong Kong Observatory and regional models had anticipated this range given the prevailing humid, overcast pattern. A stronger cold surge or prolonged clear skies could have enabled greater heat loss and a lower minimum, but observed conditions and real-time data ruled out such shifts.
