This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 10 May '26. 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.Hong Kong Observatory's latest forecast, updated at 19:50 HKT on May 9, projects a daytime high of 27°C on May 10 under mainly cloudy conditions with sunny intervals, 70-90% rain chances, and moderate easterly winds force 3-4, aligning trader consensus at 56% implied probability for 27°C. This follows May 8's 30.3°C peak but May 9's cooler mid-20s maxima amid fresh easterlies from an anticyclone aloft, which suppress insolation and advection cooler air masses. High humidity (70-90%) further caps heating potential, though brief sun could nudge toward 28°C (14.5%); climatological May highs average near 28°C, but current synoptic patterns favor the 26-27°C cluster (82% combined). Next HKO update at 11:30 HKT May 10 may refine guidance ahead of resolution based on official observations.
