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.Traders have converged on 28°C as the lowest temperature recorded in Hong Kong on August 19, 2026, reflecting official observations from the Hong Kong Observatory confirming that minimum. In August’s subtropical monsoon regime, overnight lows typically range 26–28°C amid high humidity and limited radiative cooling, with urban heat island effects in dense districts further moderating extremes. The 100% market-implied probability aligns with verified station data rather than forecasts, as post-event measurements eliminate model uncertainty. Only an unreported station anomaly or data revision could alter resolution, though historical August patterns and recent seasonal outlooks for near-normal temperatures reinforce this outcome.
