This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 13 Apr '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 9-day forecast, updated April 11, projects a maximum temperature of 26–29°C on April 13 under sunny periods and a southerly airstream bringing hot daytime conditions across Guangdong's coast, fueling trader sentiment clustered around 28°C (33.5%) and 29°C (36.5%) outcomes. This tight range reflects model consensus on above-normal April heat—seasonally favored by an anticyclone aloft suppressing clouds early next week—but with differentiation hinging on cloud interval variability and relative humidity (65–90%), which could cap peaks at 28°C via reduced solar insolation or allow 29°C on clearer afternoons akin to April 10's 28°C high. Daily HKO updates through April 12 may refine this ahead of resolution based on Observatory measurements.
