Hong Kong Observatory observations confirm a maximum air temperature of 27°C at the Observatory station on April 11, 2026, driving trader consensus to a 99.8% implied probability for this outcome amid stable subtropical high-pressure conditions fostering sunny periods and seasonal warmth. Afternoon readings across regional stations peaked between 25–28°C, aligning with April climatological norms of 26–28°C daily highs and the spring 2026 outlook for above-normal temperatures, while evening data cooled to 26°C by midnight, solidifying the daily peak. Model consensus from multi-agency forecasts anticipated this range, with low wind shear and ample insolation supporting the observed intensity. Barring rare post-midnight data revisions or measurement anomalies at official sites, higher readings like 28°C remain implausible as the resolution window closes.

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.
