Market context

Shanghai's highest temperature on 13 June 2026 will be measured at Pudong International Airport Station and resolved against historical weather data from Wunderground. The settlement window closes at midday UTC on that date, meaning the full daily maximum must be recorded before resolution.

June in Shanghai typically sees early summer conditions with daily highs ranging from 28–32°C, though heat waves can push readings into the mid-30s. The 0% crowd probability suggests traders are pricing in an expectation that the temperature will fall below the lowest available range bracket. Historical June records at Pudong show variability: the station has recorded highs as low as 22°C and as high as 37°C during the month across different years. Recent decades show a trend towards warmer June temperatures in Shanghai, with readings above 30°C becoming increasingly common. Comparable years with similar atmospheric patterns provide the baseline for assessing whether June 2026 will track towards seasonal norms or anomalies.

Traders should monitor seasonal weather forecasts released in early June 2026, particularly any alerts regarding high-pressure systems or tropical moisture patterns that could elevate temperatures. El Niño or La Niña conditions active during spring 2026 will influence whether the East Asian monsoon establishes early, which affects Shanghai's June heat profile. Real-time meteorological data from China's National Meteorological Centre, typically published weekly, will offer the most reliable forward guidance as the settlement date approaches.
