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 early April 15, projects a maximum temperature of 28°C on April 17 under a southerly airstream transitioning to a trough of low pressure, bringing mainly cloudy skies, bright periods, and a few showers that could cap heating. Trader consensus, with 38% implied probability for 29°C slightly edging 33.5% for 28°C, reflects uncertainty from recent observations—highs reached 31°C at some stations today amid hot coastal conditions—and potential for reduced cloud cover allowing greater solar insolation. Climatological April highs average around 26°C, but above-normal seasonal trends and upper-air anticyclone influences support upside risk; next forecast update at 11:30 HKT today may refine model consensus.
