Highest temperature in Hong Kong on July 18?

Platform comparison

Market context

Hong Kong's peak daily temperature on 18 July 2026 will be recorded by the Observatory's official network and published in its Daily Extract climate database. The settlement hinges on a single data point—the absolute daily maximum in Celsius to one decimal place—released after the measurement window closes at midday UTC on that date. Until the Observatory publishes its finalised reading, the market cannot resolve, creating a hard dependency on institutional data release timing rather than real-time forecasting.

July is Hong Kong's hottest month, with historical daily maxima typically ranging between 32–35°C. The 0% crowd probability reflects either extreme confidence in a specific temperature band or minimal trading activity; comparing against the Observatory's 30-year climate normals shows 18 July averages around 33.1°C, with recorded extremes reaching 36.1°C on particularly intense days. Recent summers have seen occasional excursions above 35°C during heat waves, though such events remain outliers rather than baseline expectations.

Traders monitoring this market should watch the Hong Kong Meteorological Society's seasonal outlooks and any tropical cyclone activity in the Western Pacific during early-to-mid July, as storm systems can suppress temperatures significantly. Deposit and withdrawal friction matters here: traders using SEPA transfers or Klarna's payment rails should account for settlement delays, as the Observatory typically publishes Daily Extracts within 48 hours of the measurement date. USDC on-chain settlement may offer faster liquidity access once the data is confirmed, though book depth will depend on how many traders fund positions before the resolution window closes.
