Highest temperature in Shanghai on August 17?

Platform comparison

Market context

Shanghai's highest temperature on 17 August 2026 will be recorded at Pudong International Airport Station and measured in degrees Celsius. The market resolves using Weather Underground's Daily Observations table as the authoritative source, with any divergence from the Day High & Low summary section disregarded. Settlement occurs at 12:00 UTC on that date, fixing the outcome based on observed meteorological data rather than forecast models.

August temperatures in Shanghai typically range between 28–35 °C, with occasional peaks above 36 °C during heat waves. Historical records show that mid-August often coincides with the tail end of the East Asian summer monsoon, creating variability in daily maxima. The current crowd-implied probability of 0% suggests either extreme confidence in a specific temperature range or insufficient liquidity to establish meaningful odds across all bins. Comparable weather markets on similar Asian cities have shown that crowd estimates tend to cluster around seasonal norms until within 48 hours of settlement, when actual forecasts become more actionable.

Traders should monitor China Meteorological Administration bulletins and Weather Underground's 10-day forecast updates as mid-August approaches. Typhoon activity in the Western Pacific—particularly any systems tracking toward the Yangtze River Delta region—could materially shift temperature expectations downward through cloud cover and precipitation. The regulatory framework for this market varies by jurisdiction: German traders face GlüStV licensing requirements for operators; US participants fall under CFTC oversight if the platform operates as a derivatives exchange; UK and EU residents may access markets with no-KYC verification up to £1,200 (approximately $1,500 USD equivalent), though this threshold applies per transaction or account tier depending on the platform's compliance structure.
