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 determining the settlement outcome. The market resolves against Weather Underground's Daily Observations table—the granular, station-level record rather than rounded summary figures—ensuring precision in a region where afternoon peaks regularly exceed 33°C during late August.

Historical August data from Guangzhou shows consistent patterns: the past five years have recorded daily highs between 32–35°C during mid-to-late August, with occasional spikes above 36°C during heat waves. The 0% crowd probability suggests traders are either absent or awaiting clearer atmospheric forecasting windows. Comparable Asian summer markets typically see liquidity surge 7–10 days before settlement as meteorological models converge; current flatness reflects the 18-month lead time and limited near-term visibility into regional pressure systems.

Traders should monitor tropical cyclone activity in the South China Sea and the East Asian summer monsoon's intensity through July 2026, as both significantly influence Guangzhou's August temperatures. The China Meteorological Administration publishes monthly outlooks in early August; these forecasts historically shift market expectations. Deposit friction remains material for this market's book depth—traders using Klarna's staggered payment rails or SEPA transfers into USDC liquidity pools may delay positions until late July when forecasts sharpen and volatility justifies capital deployment.
