Highest temperature in Guangzhou on August 1?

Platform comparison

Market context

The underlying event is the day’s **highest temperature at Guangzhou Baiyun International Airport Station** on 1 August, and the market is currently pricing a **0% implied chance of YES**, so the crowd is effectively saying a specific outcome band looks negligible. In practice, that makes **anything above the market’s YES threshold** the contrarian angle, while the favourite is the more conventional late-summer Guangzhou heat profile.

Historically, Guangzhou in August is a hot, humid city, with typical monthly highs around **33°C to 33.5°C** and average August maximums also clustered in the low 30s Celsius.[1][4][18][20] Comparable August records show individual days frequently reaching the **mid-30s Celsius**: one historical table lists 1 August at **33.5°C**, 2 August at **35.2°C**, and 3 August at **36°C**.[5] That matters for handicapper-style framing because a 0% implied price can still leave value in the market’s outer bands if the day turns out merely “normal hot” rather than exceptional; the consensus appears to be that the station’s top reading will land near the climatological centre rather than at a sharp outlier.

The main catalysts are not political or calendar-driven so much as meteorological: cloud cover, rainfall, and the timing of the peak heat early in the afternoon. Guangzhou’s August climate is typically very humid and wet, with precipitation around **270 mm to 297 mm** for the month and frequent rain days, which can cap the day’s maximum even when the air mass is hot.[1][2][20] Traders should watch the live Guangzhou forecast and any shifts in thunderstorm timing, because convective rain or extensive cloud early in the day would favour a lower ceiling, while a dry, sunny morning would strengthen the over on the temperature range.[10][18]
