Highest temperature in Shanghai on July 15?

Platform comparison

Market context

Shanghai will record its peak daytime heat at Pudong International Airport on 15 July 2026, with the market settling on the Celsius range containing that highest temperature. The current crowd-implied probability of 0% YES reflects a misalignment with historical July patterns, where temperatures routinely exceed 35°C.

Historical data for mid-July in Shanghai shows consistent highs between 34°C and 39°C, with 38°C being a frequent peak in recent years. Comparable cases from 2023 and 2024 saw maximums of 38.2°C and 37.9°C respectively at the same station, framing the 0% probability as statistically anomalous rather than indicative of a genuine cooling event [4]. Traders should view this as a pricing error rather than a signal of unusual weather.

Key catalysts include the daily Wunderground release at 12:00 UTC on 15 July, which will confirm the official settlement figure. Monitor the Shanghai Meteorological Bureau’s 24-hour forecast updates for any sudden shifts in cloud cover or rain, which could suppress peaks below 36°C. Recent heatwave reports from China’s National Meteorological Centre indicate persistent high-pressure systems over the Yangtze River Delta, reinforcing the likelihood of temperatures near 38°C [4]. Regulatory clarity remains critical: German GlüStV rules may restrict access for EU users, while US CFTC reach could limit participation for Americans. The ‘no-KYC up to $1,500’ threshold ensures broad accessibility for this weather market, provided users comply with local jurisdictional requirements.
