Highest temperature in Guangzhou on July 9?

Platform comparison

Market context

On 9 July 2026, the real-world event determining this market is the highest temperature recorded at Guangzhou Baiyun International Airport, with historical data showing July averages near 33°C and peaks reaching 36°C to 39°C during extreme heat periods[1][4]. The current crowd-implied probability of 0% YES suggests traders believe the temperature will fall outside the specific range defined in the market contract, despite Guangzhou’s reputation for intense summer heat where daily highs routinely hit 87°F to 100°F (30.5°C to 37.8°C)[2][8].

Historical patterns indicate that the warmest day in July typically occurs around 30 July with an average high of 32.2°C, yet extreme outliers have pushed temperatures to 39°C in recent years[1][3]. This frames the 0% probability as a reaction to the specific range threshold rather than a denial of Guangzhou’s heat, as comparable markets on 7 July 2026 showed 100% implied probability for similar temperature bands, confirming that July heat is a reliable predictor when ranges align[1]. Traders should monitor Wunderground’s daily updates for the Baiyun station and any sudden shifts in regional humidity or cloud cover that could suppress peak temperatures below the contract threshold.

Key catalysts include the release of China’s National Meteorological Centre forecasts for the Guangdong region and potential adjustments to the UMA oracle’s resolution window, which could alter settlement timing[1]. Recent weather reports from AccuWeather highlight that July 2026 forecasts show daily highs between 87°F and 100°F, reinforcing the expectation of high temperatures unless an unusual weather system intervenes[2]. For accessibility, German GlüStV regulations and US CFTC reach mean that platforms offering “no-KYC up to $1,500” allow traders to access this market without identity verification, provided they stay within the threshold, though geo-blocking may restrict access in the US, UK, and EU for direct Polymarket users[1]. This regulatory landscape ensures broad participation while maintaining compliance with cross-border financial rules.
