Hong Kong Observatory measurements confirm that the highest temperature on June 4 exceeded 34°C, with the official site reaching at least 34.2°C amid a broader heatwave that produced peaks above 35–36.7°C in multiple districts. This outcome aligns with seasonal forecasts for above-normal temperatures driven by long-term climate warming trends and prevailing atmospheric conditions favoring heat retention. The near-certain market pricing reflects verified observational data rather than models, though minor revisions in final official tallies or station-specific definitions could theoretically affect edge cases near the threshold.

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.
