Highest temperature in Hong Kong on July 20?

Platform comparison

Market context

Hong Kong faces its peak summer heat today, with the Hong Kong Observatory monitoring the highest temperature recorded on 20 July 2026 to settle this weather prediction market. The current crowd-implied probability of 0% for any specific outcome suggests traders doubt the day will reach extreme thresholds, yet historical data shows July is consistently the hottest month in the region, often pushing temperatures above 33°C.

Historical records from the Hong Kong Observatory indicate that daily maximum temperatures on 20 July have frequently exceeded 32°C in recent years, with the absolute daily max reaching 35.2°C in 2018 and 34.7°C in 2021 [1]. These comparable cases frame the 0% probability as potentially mispriced, as the city’s urban heat island effect and monsoon patterns regularly drive temperatures into the mid-30s during this period, making a low-temperature resolution unlikely based on long-term climatology.

Traders should watch the Hong Kong Observatory’s upcoming “Daily Extract” publication for the finalized “Absolute Daily Max (deg. C)” reading, which will determine the market’s resolution once data is confirmed. The settlement window closes at 12:00 UTC on 20 July 2026, meaning any delay in the Observatory’s data release could impact the final outcome, while real-time readings from the Hong Kong International Airport weather station currently show scattered clouds and temperatures around 27°C, offering a preliminary but non-definitive indicator [1].
