Trader consensus on Polymarket favors a high of 27°C at 31% implied probability for Hong Kong on March 29, driven by the latest Hong Kong Observatory (HKO) forecasts showing mostly sunny skies and light winds under a high-pressure ridge, with model ensembles from ECMWF and GFS converging on daytime maxima in the mid-to-upper 20s Celsius. Recent observations confirm warming trends, with yesterday's high reaching 26°C amid low humidity and minimal cloud cover, boosting confidence in further intensification potential absent any cold fronts. High uncertainty stems from variable afternoon convection risks and sea breeze influences, which could cap temperatures at 25-26°C or push toward 28-29°C if subsidence strengthens; historical March data shows similar setups averaging 24-27°C with a standard deviation of 2-3°C. Watch HKO's next 24-hour update for refined guidance.

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.
