The Hong Kong Observatory (HKO) recorded a maximum air temperature of 27.1°C at its headquarters on April 3, 2026, anchoring trader consensus at a 99.9% market-implied probability for the 27°C outcome as the definitive resolution criterion. This observational data from HKO's standardized instruments—issued in the early April 4 bulletin—reflects mostly cloudy conditions with minimal sunshine (1.0 hour) and no rainfall, amid a broader pattern of above-normal early-year warmth forecasted for 2026 due to persistent high-pressure influences. While final data audits are routine, challenges to this positioning would require verified equipment anomalies or measurement revisions, scenarios deemed negligible given HKO's rigorous quality controls and historical accuracy in daily maxima reporting.

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.
