This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 1 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 observations on April 1, 2026, confirm a highest temperature of 27°C recorded earlier today at the Observatory station, driving trader consensus to a 99.3% implied probability for this outcome as evening sets in with air temperatures dropping to 25°C amid mainly cloudy skies and scattered showers. Multi-model forecasts initially projected up to 28°C, but persistent cloud cover and light easterly winds have capped daytime heating, aligning with normal to above-normal seasonal temperatures for early April. Realistic challenges would require an improbable late-evening heat surge from sudden clearing, though current trends and short-term outlooks for ongoing showers make this unlikely; final daily maximum data expected from HKO by tomorrow.
