Highest temperature in Shenzhen on July 6?

Platform comparison

Market context

Shenzhen’s July 6, 2026, high temperature at Bao’an International Airport is the real-world event this market resolves on, with the crowd currently pricing a YES outcome at 0%. On Polymarket, this contract trades as a conditional token on the Polygon network, settled in USDC, where the 0% implied probability suggests traders expect the peak heat to exceed the lowest bracket by a significant margin. Historical July data for Shenzhen consistently shows highs around 32°C (90°F), with the monthly average high reaching 32°C and the average temperature sitting at 29°C [1][2]. Recent climatology places the most probable outcomes firmly in the 30°C-to-33°C range, meaning a 29°C result would require an unusual weather anomaly, such as a heavy typhoon front or prolonged cloud cover [9].

Traders should monitor the subtropical high pressure system and any incoming typhoon forecasts, as these are the primary catalysts that could suppress temperatures below the typical July peak [1]. The settlement depends entirely on Wunderground’s recorded daily maximum for Bao’an Airport, so real-time updates from AccuWeather’s July 2026 forecast—showing daily highs ranging from 86°F to 96°F (30°C to 35°C)—are critical for assessing probability shifts [3]. No official announcements are expected to alter the on-chain mechanics, but sudden changes in the regional weather schedule, such as the arrival of a monsoon system, could trigger rapid re-pricing of the conditional tokens before the 12:00 UTC settlement window closes.
