This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 19 Aug '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.Persistent showers and high humidity across Hong Kong, driven by the East Asian summer monsoon and above-normal seasonal temperatures per the Hong Kong Observatory’s August–October outlook, are anchoring overnight lows near 27°C. Multi-model consensus and AccuWeather guidance project minimums of 26–28°C for August 19 amid variable cloud cover that suppresses radiative cooling, aligning with the market’s leading outcomes at 27°C (35.5%) and 26°C (25.5%). Historical August climatology shows average lows of 26–28°C, with brief deviations possible from localized rainfall timing or urban heat-island effects. Traders weigh these near-term forecast details against ENSO-influenced warming trends, while upcoming HKO updates and refined model runs could shift probabilities if steering winds or thunderstorm intensity change.
