Recent Hong Kong Observatory observations, including maxima around 29–31°C at key stations with several sites peaking near 30°C amid partly cloudy skies and scattered showers, have locked in trader consensus at 30°C. An approaching northeast monsoon and high-level disturbance have suppressed full solar heating, keeping conditions below the 32°C forecast issued earlier in the day. This skin-in-the-game alignment reflects verified real-time data rather than models, though any late-day clearing or station-specific spike above 30°C before midnight could still alter the official daily high.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (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
In the event that there is no data for the observation date by 11:59 PM ET on the seventh day following the observation date, this market will resolve to the lowest bracket.
This market will resolve once data for this date has been published on the resolution source, or by 11:59 PM ET on the seventh day following the observation date, whichever comes first.
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.
