Hong Kong Observatory (HKO) measurements confirm the highest air temperature on April 29, 2026, peaked at 28.4°C at the Observatory site amid a southerly airstream delivering warm, humid conditions with partly cloudy skies, propelling trader-implied odds to 100% consensus on 28°C. Regional observations logged 28°C at 3 p.m., aligning with above-normal April climatology—where mean maximums average 26°C—fueled by persistent warming trends in 2026. Model forecasts had anticipated such peaks from stable high-pressure influence, minimizing surprises. Scenarios challenging this include rare data revisions from station recalibrations or equipment faults, though HKO's multi-site verification renders them improbable as final bulletins finalize.

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.
