Highest temperature in Hong Kong on July 7?

Platform comparison

Market context

The underlying event is the daily maximum temperature recorded by the Hong Kong Observatory on 7 July 2026, measured in degrees Celsius to one decimal place. Historical data frames the current 0% YES probability as a mispricing; July in Hong Kong is consistently the city’s hottest month, with mean maximum temperatures reaching 32.9°C in 2007 and 32.6°C in multiple recent years like 2014 and 2016[9]. AccuWeather’s forecast for July 2026 predicts daily highs between 86°F and 95°F (30°C to 35°C), confirming that extreme heat is the norm rather than an anomaly[2]. The Hong Kong Observatory itself noted July 2023 as the hottest month on record, with the highest number of hot days and nights since 1884, reinforcing that high temperatures are statistically probable[8].

Traders should monitor the Hong Kong Observatory’s finalisation of the “Daily Extract” for 7 July 2026, which is the sole resolution source for this market[4]. Recent news from the South China Morning Post highlights that July 2023 broke records for hot days, suggesting a potential catalyst if similar conditions persist in 2026[8]. The market’s traction is directly tied to funding flows; as depositors use Klarna or SEPA rails to enter positions, the book depth expands, reflecting confidence in the historical trend of extreme July heat. Withdrawal rails like USDC further facilitate liquidity, ensuring that the market’s pricing adjusts rapidly to new temperature announcements or schedule updates from the Observatory[1]. Dependencies include the timely publication of the Daily Extract, which must be finalized before the market can resolve.
