This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 17 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 at 11:30 HKT on April 15, projects a 25–29°C temperature range for April 17's high amid mainly cloudy conditions with a few showers and hot sunny intervals under light southerly winds force 2–3, driving trader sentiment toward 29°C (37%) and 28°C (33%) as leading outcomes. Recent observations today reached 31°C at select stations like Tai Po amid persistent southerly airstream warmth, aligning with the seasonal above-normal temperature outlook for April–June, but an approaching trough of low pressure raises medium rain probability (75–95% RH), potentially capping peaks via cloud-induced cooling while sunny breaks enable solar heating to push toward 29°C. Model uncertainty in shower coverage and timing differentiates the close odds; watch the afternoon forecast update for refinements.
