Highest temperature in Chongqing on July 2?

Platform comparison

Market context

Chongqing’s July heat is notorious, with daytime averages hovering near 33°C and extreme spikes reaching 44°C in past summers[2][3]. On Polymarket today, the contract for “Highest temperature in Chongqing on July 2” shows 26°C as the frontrunner at 27% implied probability, while the 0% YES price for any temperature above a specific threshold reflects market caution about regional moderation[1]. Traders are betting that typical furnace-like intensity will be tempered by humidity and rain, a pattern seen in recent July forecasts where perceived temperatures peaked around 38°C despite highs near 40°C[5].

Historically, Chongqing’s weather remains changeable, with heavy rain and brief storms common in July and August, often lowering peak temperatures despite high humidity[6]. The city, dubbed one of China’s “Four Furnaces,” frequently sees temperatures soar above 35°C, yet fog and rainfall can disrupt extreme heat events[7]. For this market, the catalyst to watch is Wunderground’s daily data release for the Jiangbei International Airport Station, which will confirm the day’s maximum temperature in whole degrees Celsius[1]. Traders should monitor local meteorological announcements for rain forecasts, as recent weather guides note that July frequently brings heavy downpours that cap maximums below 40°C[5]. On-chain mechanics on Polygon using USDC and conditional tokens will lock in these probabilities until settlement on 2026-07-02T12:00:00Z[1].
