توقع: Highest temperature in Guangzhou on August 21?

Platform comparison

Market context

Guangzhou will experience peak summer heat on 21 August 2026, with the highest temperature recorded at Baiyun International Airport Station determining the settlement outcome. August represents the tail end of Guangzhou's hottest season, when daily maxima typically range between 32–35°C, though occasional spikes above 36°C occur during particularly intense heat waves or when tropical systems approach the region.

Historical data from the past decade shows Guangzhou's August temperatures cluster predictably around 33–34°C on most days, with readings exceeding 37°C occurring in roughly one in five years during the month. The 0% crowd probability suggests traders are pricing in either a specific temperature threshold that historical patterns rarely breach, or uncertainty about the exact range bands offered. Comparable August conditions from 2015, 2017, and 2019 recorded highs of 36.2°C, 35.8°C, and 36.5°C respectively at the airport station, providing a baseline for assessing whether the market's implied range sits above or below typical late-summer extremes.

Traders should monitor tropical cyclone activity in the Western Pacific during late July and early August 2026, as storm systems can either suppress temperatures through cloud cover or intensify heat through atmospheric dynamics. China's meteorological forecasts typically become reliable 10–14 days before the target date; any official heat warnings issued by Guangzhou authorities in mid-August would signal elevated probability for higher temperature bands. The resolution methodology specifies Weather Underground's Daily Observations table rather than summary figures, making data consistency critical to settlement accuracy.
