Highest temperature in Shanghai on July 28?

Platform comparison

Market context

Shanghai's Pudong International Airport Station will record a daily high temperature on 28 July 2026, measured in Celsius and logged by Weather Underground's historical database. The settlement hinges on the single highest reading across all times that day at this specific monitoring location, with resolution occurring at 12:00 UTC on the settlement date.

July temperatures in Shanghai typically range between 32–36°C, with occasional peaks above 37°C during heat waves. Historical data from the past decade shows that extreme heat events—those exceeding 39°C—occur roughly once every two to three years in midsummer, though such occurrences remain statistically uncommon for any given date. The 0% crowd probability suggests traders are pricing in either confidence in moderate conditions or uncertainty about the resolution mechanism itself. Comparable weather markets on this platform have shown that single-day temperature extremes are difficult to predict with precision more than a few days in advance, particularly in subtropical regions where microclimatic variation and urban heat island effects create volatility.

Traders should monitor China Meteorological Administration forecasts released in early July 2026, which typically provide 10–14 day outlooks for major cities. Tropical cyclone activity in the Western Pacific during late July can significantly alter Shanghai's weather patterns, either suppressing heat through cloud cover and precipitation or intensifying it through atmospheric circulation changes. Real-time atmospheric pressure systems and any official heat warnings issued by Shanghai authorities in the week preceding 28 July will serve as immediate catalysts for probability shifts.
