This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 4 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 official forecasts from the Hong Kong Observatory indicate daytime highs of 27–32°C for July 3–4 amid partly cloudy skies and scattered showers, keeping trader consensus centered on 28–29°C outcomes. These conditions reflect typical early-July monsoon influences and moderate moisture convergence that limit solar heating, while subtle differences in model runs for cloud cover and timing of any rain distinguish the narrow spread among 28°C, 29°C, and 30°C probabilities. Hong Kong’s seasonal outlook for normal-to-above-normal July temperatures, driven by long-term warming trends, provides background support but yields to short-term synoptic variability near resolution. Updated HKO guidance and numerical weather prediction consensus over the next 48 hours will likely refine these market-implied odds.
