Highest temperature in Shanghai on August 16?

Platform comparison

Market context

Shanghai's highest temperature on 16 August 2026 will be measured at Pudong International Airport Station and resolved against Weather Underground's Daily Observations table. The market currently shows 0% probability across all temperature ranges, suggesting traders have not yet engaged with this weather-specific contract ahead of the two-year settlement window.

August temperatures in Shanghai historically cluster in the 32–36°C range during mid-month, with occasional peaks exceeding 37°C during heat waves. The city's subtropical climate produces consistent summer heat, though specific daily maxima vary based on cloud cover, precipitation, and atmospheric pressure patterns. Historical data from the China Meteorological Administration shows that August 16 has recorded temperatures between 30°C and 38°C over the past two decades, providing a baseline for assessing which temperature bands carry realistic probability weight. The absence of current trading activity likely reflects the distant settlement date rather than fundamental uncertainty about Shanghai's August weather patterns.

Traders monitoring this market should track seasonal weather forecasts released in early August 2026, particularly from the China Meteorological Administration and international models. El Niño or La Niña conditions developing through 2025–2026 could influence summer temperature patterns across East Asia. The specific resolution methodology—prioritising Weather Underground's Daily Observations table over summary figures—requires confirmation that this data source maintains consistent station coverage through the settlement window. Any disruptions to Pudong Airport's weather monitoring equipment would create resolution ambiguity.
