Hong Kong Observatory's latest forecast drives trader consensus toward a 27°C high on March 27 at 33.5% implied probability, projecting sunny intervals under a high-pressure ridge fostering solar heating and minimal cloud cover. Closely matched 26°C (27.5%) and 28°C (22.5%) odds stem from ensemble model divergences—ECMWF leans slightly cooler with southerly sea breezes moderating urban heat island effects, while GFS runs hotter in drier scenarios—against a March historical average of 23-25°C. Uncertainty persists in afternoon peak timing and humidity-driven evaporative cooling, with final observations resolving the market.

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.
