Highest temperature in Shanghai on July 14?

Platform comparison

Market context

Shanghai's highest temperature on 14 July 2026 will be recorded at Pudong International Airport Station and settled against historical data from Wunderground. The 0% crowd-implied probability suggests traders are either heavily concentrated in lower temperature bands or the market has attracted minimal liquidity. July in Shanghai typically sees peak summer heat, with daily highs routinely exceeding 32°C during mid-month, making extreme temperature outcomes a baseline expectation rather than an outlier.

Historical records from Shanghai's meteorological station show July averages around 32–34°C, with occasional spikes to 37–38°C during heat waves. The 2013 heat wave pushed temperatures to 40.8°C, whilst more recent summers have remained within the 35–37°C range. These precedents establish that moderate-to-high temperature bands (32–36°C) represent the statistical centre of gravity, whilst anything below 30°C would constitute a significant weather departure. The current zero probability across all resolution bands suggests either a data lag or minimal market participation rather than genuine trader consensus on cooler conditions.

Traders should monitor China Meteorological Administration forecasts released in early July 2026, which typically provide 10-day outlooks for major cities. El Niño or La Niña patterns active during northern hemisphere summer can influence East Asian monsoon behaviour and regional temperature volatility. Shanghai's urban heat island effect—particularly pronounced around the airport's industrial surroundings—tends to elevate recorded highs by 1–2°C relative to surrounding rural areas. Cross-platform comparison data remains unavailable until sportsbooks and competing prediction markets establish positions on this contract.
