This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 7 Jul '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 consensus forecasts point to daytime maxima of 30–31°C on July 7 under typical early-July subtropical conditions featuring light southerly flow, high humidity, and variable cloud cover. These values align with the market’s closely matched leading outcomes because small differences in insolation, timing of any showers, or urban heat-island effects can shift the daily high by 1–2°C. Above-normal seasonal temperatures noted in the July–September outlook raise the chance of brief clears that could push readings to 33°C or higher, while increased monsoon moisture or stronger winds favor the 28–29°C range. Short-range model updates through the weekend remain the key variable for final resolution.
