Highest temperature in Shenzhen on July 17?

Platform comparison

Market context

Shenzhen’s highest temperature on 17 July 2026 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 contract at 0% for the YES outcome, implying the crowd expects the temperature to fall outside the specific range tied to that binary option, while the frontrunner outcome is 27°C at 70% probability and 28°C at 21% [1].

Historically, July in Shenzhen is the hottest month, with a daily average of 32°C and typical highs reaching 32°C against lows of 26°C, though subtropical highs and typhoons often bring 17 rainy days and 339 mm of precipitation [2]. The current 0% YES probability aligns with this pattern if the binary range excludes the 27–28°C band, as the market’s top outcomes cluster just below the monthly average high, suggesting traders view a cooler, rain-affected day as more likely than a dry, extreme heat spike.

Traders should monitor the daily Wunderground history for the Bao’an station, which serves as the official resolution source, and watch for typhoon forecasts or subtropical high announcements that could suppress temperatures below 27°C [2]. Since settlement ends at 12:00 UTC on 17 July 2026, any late-morning rain or cloud cover reported by local meteorological services could shift conditional token demand on Polygon, where USDC trades settle the outcome without intermediary delay.
