Hong Kong Observatory forecasts and aligned numerical weather models indicate a daily maximum of 28°C on June 9, supported by extensive cloud cover, scattered showers, and a moderating sea breeze that restricted solar heating amid typical early-summer humidity levels exceeding 80 percent. These conditions aligned with seasonal baselines for the region, where June maxima often reach 30–32°C under clearer skies but are suppressed by persistent moisture and reduced insolation. Trader consensus at near-100 percent implied probability for the 28°C outcome reflects high confidence in official station readings, with only modest upside risk from any late-afternoon clearing that failed to materialize.

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
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.
