Official measurements from the Hong Kong Observatory established a daily minimum of exactly 25°C on June 15, driving the market's near-certain 100% implied probability for that outcome. This aligns with June climatology, where overnight lows typically range 24–27°C amid the southwest monsoon, and seasonal outlooks had projected above-normal warmth overall. Model consensus ahead of the date showed limited overnight cooling potential, with no major frontal systems or enhanced cloud cover to push readings lower. Traders weighted the Observatory's calibrated station data heavily, as it serves as the definitive resolution source. A last-minute instrument calibration issue or localized microclimate anomaly remains theoretically possible but lacks supporting evidence from regional networks.

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.
