Recent observational data from the Hong Kong Observatory shows the maximum temperature on May 15 reached 27°C under stable subtropical high-pressure conditions typical for mid-May in the region. This aligns with long-term climatological averages of 26–28°C and consistent model outputs from regional weather agencies that projected minimal variability due to moderate sea-surface temperatures and absent frontal systems. The market’s 99.9% implied probability for 27°C reflects this strong consensus in verified measurements. Realistic challenges remain limited but could arise from post-event quality-control adjustments or rare microclimate anomalies at the official station, though historical precedents for such revisions in Hong Kong records are infrequent.

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.
