Highest temperature in Hong Kong on July 14?

Platform comparison

Market context

On 14 July 2026, the Hong Kong Observatory will record the day's highest temperature in degrees Celsius. This market resolves to whichever temperature band contains that single daily maximum reading, sourced from the Observatory's published "Absolute Daily Max" figure once the "Daily Extract" for that date is finalised and made available through their climate information system.

July in Hong Kong sits within the summer monsoon season, when daily maxima typically range between 31–34°C, though heat waves can push readings above 35°C. Historical data from the Observatory shows that extreme heat days (36°C+) occur roughly once per summer, whilst readings below 30°C are rare during this month. The 0% crowd probability suggests the market is either awaiting range definitions or reflects genuine uncertainty about which specific band will be hit. Comparable July dates from recent years provide calibration: the Observatory's online archive allows traders to cross-reference 2023, 2024, and 2025 July 14th readings to establish baseline expectations and volatility patterns.

Traders building conditional orders or automated monitoring should note that the Observatory publishes daily climate extracts on a fixed schedule, typically available by mid-morning the following day. Weather forecasts from the Observatory and international models (GFS, ECMWF) become increasingly reliable 5–7 days ahead; tracking these alongside tropical cyclone alerts and upper-air pressure patterns will signal whether anomalous heat or cooler-than-typical conditions are probable. The settlement window closes at 12:00 UTC on 14 July, giving traders a narrow window to react once preliminary data surfaces, though final resolution depends on the Observatory's official publication timeline.
