Highest temperature in Shanghai on July 6?

Platform comparison

Market context

The underlying real-world event is the highest temperature recorded at Shanghai Pudong International Airport on 6 July 2026, measured in degrees Celsius. Current Polymarket pricing for this contract sits at 0% YES, implying the market believes the temperature will not reach the specific threshold required for a "yes" outcome. This conditional token, settled in USDC on the Polygon network, reflects a collective dismissal of extreme heat for this date, despite the region entering its peak summer period.

Historical data frames this probability as plausible rather than reckless. Average daily highs at Shanghai Pudong in July typically range from 84°F to 88°F (29°C to 31°C), rarely falling below 75°F or exceeding 95°F [1]. While July temperatures often hover above 30°C and can exceed 35°C during hotter spells, the 0% probability suggests traders expect conditions to remain within the standard band rather than spike to the extreme upper limit [7]. Recent June forecasts showed highs around 33°C, indicating a gradual warming trend rather than an immediate surge to record-breaking levels [4].

Traders should monitor the official weather schedules and any sudden announcements regarding heatwaves or monsoon activity that could alter the forecast. The resolution depends entirely on Wunderground data for the highest temperature recorded at any time on this day, making real-time monitoring of the station critical [5]. Although no specific recent news source predicts an anomaly for 6 July, the general pattern of hot, rainy, and humid weather in Shanghai suggests volatility remains a key dependency [7]. The settlement window closes at 12:00 UTC on 6 July 2026, requiring precise attention to the final hourly readings from the Pudong station [3].
