Highest temperature in Hong Kong on July 25?

Platform comparison

Market context

Hong Kong’s peak temperature on 25 July will be set by the Hong Kong Observatory’s daily maximum reading, and the market is currently pricing only a very small chance of the top outcome. In late July, Hong Kong is normally hot and humid, with average highs around 32°C and a long-run daily high for 25 July close to 32°C to 32.2°C, while observed daily highs in July are usually clustered near the low 30s and rarely push above the mid-30s.[1][4][5]

That makes the crowd-implied 2% for the highest bracket look like a severe outlier unless conditions are unusually extreme. Comparable cases show that Hong Kong can briefly spike well above seasonal norms: the Observatory recorded 36.1°C on a July day in one recent heat event, and other reports have cited 37°C readings during typhoon-adjacent heat.[3][6] But those are exceptional outcomes rather than base-rate July behaviour, which is why probabilities far into the upper tail tend to stay low unless a heatwave or clear-sky setup is locked in.[1][5]

For traders, the main catalysts are the Observatory’s short-range forecast, any heat warnings, and whether the weather turns more settled or stays showery in the run-up to the settlement window. Polymarket’s market page currently points to a 33°C forecast with moisture and showers, and notes that persistent rainfall has already favoured cloud cover that limits daytime heating, keeping extremes near the seasonal average rather than at record levels.[2] The key dependency is whether that forecast warms further or gets trimmed by rain, which would materially shift the probability of the upper temperature bins.[2]
