Hong Kong Observatory (HKO) measurements confirm the highest temperature on May 4, 2026, reached 28°C at midday under partly cloudy skies, as moderating northeast monsoon winds eased following a thunderstorm warning cancellation late that evening. This aligns precisely with May's climatological normal maximum of around 28°C at the Observatory headquarters and HKO's seasonal forecast of normal to above-normal temperatures for May-July amid transitioning monsoon patterns. Trader consensus at 100% implied probability for 26°C or higher reflects this verified observational data from the Absolute Daily Max in HKO's Daily Extract, with resolution pending finalization. Realistic challenges would require an unprecedented data revision post-finalization, as short-range model consensus had anticipated sufficient solar heating to surpass 26°C thresholds.

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 to "Yes" until data for this date has been finalized.
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 finalized for this market's timeframe will not be considered for this market's resolution.
