Highest temperature in Shanghai on July 13?

Platform comparison

Market context

Shanghai will experience its peak summer heat on 13 July 2026, with the Shanghai Pudong International Airport Station recording the day’s highest temperature in degrees Celsius. Historical data shows July highs regularly exceed 30°C, often reaching 35°C during sunny spells, while the hottest day of the year typically occurs around 28 July with averages between 26°C and 31°C [1][5]. The current 0% YES crowd-implied probability suggests traders expect the temperature to fall outside the specific range offered, though comparable July records include an all-time high of 40.6°C (105°F) recorded on 26 July in Shanghai, indicating extreme heat is possible [10].

Traders should monitor real-time forecasts from Wunderground and local meteorological updates for sudden heatwave developments, as Shanghai’s summer climate is influenced by increasing solar energy and wind speeds during July [1][2]. Recent heatwave activity in East Asia, including new forecasts moving into the region, could act as a catalyst for higher temperatures [10]. The settlement depends entirely on the official Wunderground record for ZSPD, making data latency or station anomalies a key risk.

Regulatory access hinges on jurisdiction: German GlüStV may classify this as a gambling product requiring licensing, while US CFTC rules could extend reach to prediction markets involving commodity-linked outcomes like weather. The ‘no-KYC up to $1,500’ threshold allows traders in non-restricted jurisdictions to access this market without identity verification, enhancing accessibility for those under $1,500 exposure limits, though compliance obligations remain with the platform operator.
