Hong Kong Observatory official observations recorded a daily minimum of exactly 25°C on August 21, 2026, at the headquarters station, locking in the near-certain market outcome. This aligned with pre-event forecast guidance projecting overnight lows of 25–27°C under typical late-summer conditions, including moderate humidity and light winds that limited further cooling. Historical August climatology shows mean minima near 26–27°C, so 25°C represented a modest but plausible dip driven by localized radiative cooling overnight. Trader consensus reflected high confidence in the authoritative HKO reading resolving the contract, as alternative stations or revised data releases are unlikely to alter the reported value. Only an unprecedented post-observation correction or station-specific anomaly could shift the result.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 21 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.Hong Kong Observatory official observations recorded a daily minimum of exactly 25°C on August 21, 2026, at the headquarters station, locking in the near-certain market outcome.
