Hong Kong Observatory's latest forecast drives trader optimism for a high near 27°C on March 24, with models like ECMWF and GFS converging on southerly winds ushering warm, moist air masses over the region, boosting the 27°C (18%) and 28°C+ (22%) odds. March climatology shows average highs around 23°C, but lingering El Niño influences and urban heat island effects in Kowloon elevate baselines, while low precipitation probabilities (under 20%) favor clear skies and peak solar insolation. Tight clustering among 25-28°C outcomes (67% combined) reflects forecast uncertainty from divergent ensemble spreads—cloud cover variability could shave 1-2°C off peaks—tempering bets on extremes amid recent 25°C days.

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.
