Hong Kong Observatory's official observations confirmed a maximum temperature of 27°C at its King's Park station on April 27, 2026, anchoring trader consensus at 100% market-implied probability for this outcome amid scattered showers from upper-air disturbances over Guangdong that suppressed daytime heating. This aligns with April's mean maximum so far at 27.9°C, consistent with normal to above-normal seasonal temperatures under a weakening northeast monsoon influence. Localized cloud cover and moderate humidity limited further intensification, matching model consensus from prior forecasts. Realistic challenges are negligible post-resolution, barring an unprecedented data revision from quality-controlled measurements—historical audit rates for such stations are under 0.1%. Traders await similar updates for April 28 amid an approaching cold front expected to drop highs to 26°C.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 27 Apr '26.
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.Hong Kong Observatory's official observations confirmed a maximum temperature of 27°C at its King's Park station on April 27, 2026, anchoring trader consensus at 100% market-implied probability for this outcome amid scattered showers from upper-air disturbances over Guangdong that suppressed daytime heating.
