Highest temperature in Shanghai on July 25?

Platform comparison

Market context

Shanghai's summer temperatures in late July typically peak between 32–36°C, with occasional excursions toward 37–38°C during heat waves. The city's humid subtropical climate produces consistent afternoon highs in this range, though the exact daily maximum depends on cloud cover, wind patterns, and any tropical systems tracking toward the Yangtze River Delta. Pudong International Airport, the official measurement station for this market, sits in an urban-industrial zone where heat-island effects can elevate readings relative to surrounding areas.

Historical July data from Shanghai shows that temperatures exceeding 35°C occur roughly 40–50% of days in the month, whilst readings above 37°C are less frequent but not exceptional. The 0% crowd probability currently assigned suggests either extreme confidence in a cooler-than-normal outcome or minimal trading activity establishing a floor price. Comparable late-July markets in prior years have typically seen meaningful liquidity only once weather forecasts narrow to 7–10 days out, when model consensus solidifies around specific temperature bands.

Traders monitoring this market should track the China Meteorological Administration's extended forecasts and any tropical cyclone activity in the Western Pacific during early-to-mid July 2026, as such systems can suppress temperatures or trigger sudden heat spikes. Deposit flows via Klarna and SEPA rails typically accelerate as settlement approaches, deepening order books in weather markets with previously thin participation. The settlement window closes at midday UTC on 25 July, requiring traders to fund positions well before that date to avoid payment-processing delays.
