Pronóstico: Highest temperature in Hong Kong on July 31?

Platform comparison

Market context

Hong Kong’s highest temperature on 31 July is a one-day weather print, and the market is currently pricing an outcome that would sit at the very bottom of the observed distribution. The Hong Kong Observatory’s July records show a city where extreme late-summer heat is common enough to matter: the highest monthly maximum temperature in July on record is 35.7°C, with 35.6°C and 35.4°C close behind, and the Observatory said July 2023 produced a 36.1°C peak, one of the highest July readings on record.[2][8] That backdrop makes a 0% YES price look aggressive if the settlement band is anything meaningfully above a modest daytime maximum, because Hong Kong regularly posts low-30s temperatures in July and can still spike higher when conditions line up.[4][5][7]

For traders, the key catalyst is not a fixture list but the midday-to-afternoon evolution of the weather and the Observatory’s final “Absolute Daily Max” after the day closes.[1][11] The current official reading at 2 p.m. was 31°C at the Observatory, with several urban sites already at 31–33°C, including Cheung Chau at 33°C and Kowloon City, Happy Valley, Wong Tai Sin and Kai Tak Runway Park at 32°C, which keeps the door open for a higher late-day print if sunshine persists.[4] The market cannot resolve until the Daily Extract is published, so the live line will hinge on whether cloud, sea breeze or showers cap the afternoon, or whether inland stations continue to edge higher before the final HKO update.[1][4]
