Highest temperature in Shenzhen on July 6?

Platform comparison

Market context

The underlying real-world event concerns the peak temperature recorded at Shenzhen Bao’an International Airport on 6 July 2026, with the market currently pricing a 0% chance that the heat will reach the 31°C threshold. On Polymarket, this conditional token contract trades on the Polygon network using USDC, where the zero probability reflects the crowd’s conviction that the day will remain cooler than the specified range, despite the settlement window closing at 12:00 UTC.

Historical data frames this probability starkly: July is Shenzhen’s hottest month, with an average high of 89°F (31.7°C), and official records consistently show maximums well above 30°C, making a sub-31°C outcome statistically rare [3][7]. Recent climate anomalies in southern China have pushed temperatures to record highs across 578 observatories, suggesting that a cool July day would be an exceptional deviation from the norm rather than the expected baseline [8].

Traders should monitor the daily Wunderground release for the Bao’an station, as the resolution depends entirely on this specific dataset rather than general city forecasts [9]. While no immediate weather announcements are scheduled, the dependency on the 2026 historical archive means that any sudden shifts in monsoon patterns or cloud cover before noon UTC could alter the final reading, so real-time updates from the station’s hourly logs are the critical catalyst to watch [5].
