Highest temperature in Shanghai on July 3?

Platform comparison

Market context

The real-world event determining this market is the highest temperature recorded at Shanghai Pudong International Airport on 3 July 2026, measured in degrees Celsius. Historical data for early July shows Shanghai’s average daily highs range from 26–31°C, with peaks typically occurring around 3 PM; in July 2025, the temperature reached 38°C [2]. While 3 July is statistically one of the cooler days in early July, averaging 24.3°C, seasonal norms and recent heat trends suggest warmer outcomes are plausible, aligning with the 31.5% crowd-implied probability for 29°C on similar platforms [4][6]. The current 0% YES probability likely reflects a specific temperature threshold being set unusually high, not an absence of heat.

Traders should monitor daily weather bulletins from China’s National Meteorological Centre and real-time updates from Wunderground, the official resolution source [2]. A key catalyst is the onset of the “plum rain” season’s tail end, which can bring sudden humidity spikes and heatwaves; AccuWeather forecasts daily highs between 83–95°F for July 2026, with overnight lows of 75–82°F [7]. Recent reports note that outdoor activities are best scheduled before 11 AM or after 5 PM due to peak heat exceeding 28°C [2]. Regulatory accessibility hinges on jurisdiction: German GlüStV may restrict unlicensed platforms, while US CFTC rules apply to derivatives-like markets. The “no-KYC up to $1,500” clause allows broader access for retail participants in markets not classified as securities, though compliance varies by region.
