Persistent subtropical ridging combined with light southerly flow has suppressed overnight radiative cooling across Hong Kong, producing Hong Kong Observatory guidance and ensemble model consensus for a minimum temperature of 29°C on May 26. This atmospheric setup maintains elevated nighttime readings typical of late-spring conditions in the region, where average lows often range from 25–28°C. Traders have priced the 29°C outcome at 100% implied probability, reflecting the limited scope for significant deviation under current steering patterns and moisture profiles. A rapid increase in cloud cover, stronger northerly winds, or localized rainfall could enhance cooling and shift the recorded low, though such changes appear unlikely before final verification.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Min (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.
