This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 18 Jun '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 until data for this date has been published. 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 initially published for this market's timeframe will not be considered for this market's resolution.Recent Hong Kong Observatory guidance and multi-model forecasts indicate unsettled conditions with showers and thunderstorms likely on June 18, supporting trader consensus around 28–30 °C as the most probable daily maximum. Seasonal outlooks already flag above-normal temperatures for the June–August period due to long-term warming trends, yet short-term variability from moisture and cloud cover introduces meaningful uncertainty that narrows the odds on extremes. Key variables include steering flow strength, convective timing, and localized urban heat effects, all of which can shift the peak by 1–2 °C. Updated HKO and numerical weather prediction runs over the next 48 hours will provide the clearest signals ahead of market resolution.
