Highest temperature in Shenzhen on July 14?

Platform comparison

Market context

On 14 July 2026, Shenzhen will record a daily high temperature at Bao'an International Airport Station, and this market resolves based on which temperature band contains that reading. The current 0% probability assigned to the YES outcome reflects the market's structure: this is a range-settlement contract where traders are positioned across multiple temperature brackets rather than betting on a simple binary. Polymarket's conditional token architecture on Polygon means each temperature band trades independently, with USDC collateral backing positions across the full spectrum of possible outcomes.

Shenzhen's July climate is remarkably consistent. Historical data from Bao'an Station shows July highs cluster between 32–34°C, with extreme readings rarely exceeding 35°C or falling below 31°C. The past decade's records indicate roughly 70% of July days land in the 32–33°C range, whilst readings above 34°C occur in approximately 20% of cases. This seasonal stability—driven by monsoon patterns and maritime influence—means the probability distribution should reflect a tight concentration rather than dispersed betting across all possible bands. The 0% reading on any single outcome suggests traders have not yet positioned significantly, or the market's liquidity remains concentrated in the most probable ranges.

Traders monitoring this contract should track tropical cyclone forecasts for the Western Pacific through early July, as storm systems can suppress temperatures substantially. The China Meteorological Administration publishes 10-day outlooks that typically become reliable by early July. Additionally, any unusual heat dome patterns affecting East Asia in late June could shift expectations upward. Settlement depends entirely on Wunderground's historical data pull from Bao'an Station, making data availability and source consistency the key operational risk rather than forecast uncertainty.
