Hong Kong Observatory (HKO) measurements confirm the highest temperature on April 13, 2026, reached exactly 29°C at the Observatory station under a moderate southerly airstream bringing warm, humid air from the South China Sea, with sunny periods enhancing daytime heating. This aligns with seasonal forecasts of normal to above-normal temperatures for April, supported by climatological data showing typical mid-month highs around 26–28°C but elevated by stable high-pressure influence. Trader consensus at 100% on 29°C reflects this verified observational data from HKO's automated weather stations, which use standardized maximum air temperature readings. Revisions are exceedingly rare post-validation, though an extraordinary data correction or station malfunction probe could theoretically challenge it, pending HKO's final monthly summary.

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.
