Highest temperature in Shenzhen on July 13?

Platform comparison

Market context

On 13 July 2026, Shenzhen’s highest temperature will be recorded at the Bao’an International Airport Station, with the market resolving to the Celsius range containing that peak. Today, Polymarket prices the YES contract at 0%, implying the crowd believes the temperature will fall outside the specified range, despite July being Shenzhen’s hottest month historically.

Historical data shows Shenzhen’s average July high is 32°C (90°F), with 13 July specifically averaging 32°C and often featuring thunderstorms or rain that suppress peak temperatures [1][9]. In 2022, parts of China hit 40.9°C on 13 July, but Shenzhen’s airport station typically remains cooler due to coastal influence and frequent rainfall [6]. The current 0% probability likely reflects expectations of rain or cloud cover, consistent with July’s 17 rainy days and 340 mm average precipitation [1].

Traders should monitor the daily Wunderground update for ZGSZ at 12:00 UTC on 13 July, which serves as the official resolution source [market description]. Key catalysts include the China Meteorological Administration’s weekly heatwave advisories and typhoon forecasts, as subtropical highs and typhoons heavily influence July temperatures [1]. A recent Reuters report noted China’s record-hot July overall, but local Shenzhen conditions depend on immediate cloud and rain patterns rather than national averages [4][6]. Watch for real-time updates on PredictWind or Timeanddate for passing clouds and wind shifts that could alter the peak [3][8].

Is this market available outside the US?

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
