Highest temperature in Chongqing on August 14?

Platform comparison

Market context

Chongqing will experience peak summer heat on 14 August 2026, with the highest temperature recorded at Jiangbei International Airport Station determining the settlement outcome. The market currently prices at 0% YES across all temperature bands, reflecting the settlement window's two-year horizon and the inherent difficulty in forecasting specific daily extremes at such distance. Resolution hinges on the Daily Observations table from Weather Underground rather than summary figures, a distinction that matters when airport stations record multiple readings throughout the day.

Chongqing's August climate presents a consistent baseline: the city ranks amongst China's hottest urban centres, with average daily highs around 33–34°C during mid-August. Historical data from the past decade shows Jiangbei station regularly records temperatures between 35–38°C in this period, with occasional spikes above 39°C during particularly intense heat waves. The 2022 summer saw sustained temperatures exceeding 40°C across multiple days in late August, though mid-August typically remains slightly cooler than late-month peaks. These patterns establish the likely range traders should reference when evaluating probability distributions across the available bands.

Traders should monitor China's seasonal weather forecasting updates, typically released by the China Meteorological Administration in early August 2026, which provide 10-day outlooks for major cities. El Niño and La Niña cycles influence East Asian summer patterns; current climate indices suggest monitoring ENSO conditions through 2026. Urban heat island effects at Chongqing's airport location—situated in an expanding industrial zone—may contribute to marginally higher readings than surrounding rural areas, a factor worth tracking as development continues.
