Highest temperature in Hong Kong on July 9?

Platform comparison

Market context

The Hong Kong Observatory will record the highest temperature on 9 July 2026, resolving this market into a specific Celsius range. Current crowd-implied probability sits at 0% for any outcome, suggesting traders view the event as impossible or data as unavailable, yet seasonal forecasts indicate July temperatures in Hong Kong are expected to be normal to above-normal[1]. Historical data shows the Observatory has recorded ten days with maximum temperatures equal to or exceeding 35.0°C in recent periods, alongside 21 consecutive hot nights starting from 9 July[6]. AccuWeather projects daily highs for July 2026 between 85°F and 95°F (approximately 29.4°C to 35.0°C), with an average high of 89°F (31.7°C)[2]. A recent record of 36.1°C was broken in 2026, surpassing the 1963 benchmark of 35.5°C, confirming the potential for abnormally high heat[3].

Traders must monitor the finalisation of the "Daily Extract" data from the Hong Kong Observatory, as the market cannot resolve until this official publication occurs[5]. The key catalyst is the release of the "Absolute Daily Max (deg. C)" for the specified date, which measures temperature to one decimal place. While no specific announcement schedule exists beyond the standard climate data release, the dependency on finalized data creates friction for immediate settlement. The market’s traction correlates directly with funding flows; as deposit fees and withdrawal rails like SEPA and USDC become more efficient, book depth increases, allowing larger positions on these temperature outcomes. Recent news highlights Hong Kong sweltering under year’s highest temperatures, reinforcing the relevance of monitoring real-time observatory updates[4].
