The Hong Kong Observatory's latest nine-day forecast, issued May 16, projects overnight lows between 25 and 29°C on May 18 under mainly cloudy skies, scattered showers, and moderate southeast winds. High relative humidity of 75–95 percent maintained by a lingering trough over the northern South China Sea suppresses nocturnal radiative cooling, anchoring the minimum near the upper end of the historical mid-May range of 24–25°C. Traders therefore assign the highest implied probabilities to exactly 25°C and 24°C, with smaller shares on 28°C or higher reflecting residual uncertainty in cloud thinning or brief clear intervals that could permit slightly stronger cooling. The next HKO bulletin, expected this afternoon, will refine model guidance ahead of the resolution window.

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.
