Highest temperature in Shanghai on July 11?

Platform comparison

Market context

Shanghai’s July heat is a near-certainty, with the Pudong Airport station routinely recording highs above 30°C and often breaching 35°C during sunny spells. The market’s 0% YES crowd-implied probability for any specific temperature range suggests the consensus has priced in an extreme outlier or misread the settlement mechanics, as historical data shows July is the hottest month, averaging 87°F (30.6°C) with highs rarely below 75°F [1][2]. Comparable cases from recent years confirm that temperatures exceeding 35°C are common in mid-July, making a zero-probability stance on any plausible range appear fundamentally flawed unless the market is betting on a record-breaking cold snap that contradicts all seasonal norms [6].

Traders should monitor the Wunderground daily history feed for the Pudong station as the primary settlement source, watching for real-time METAR updates from the National Weather Service which track current conditions at ZSPD [9]. The immediate catalyst is the day’s weather pattern: current forecasts for Saturday 11 July indicate gusty winds, rain, and a high of 32°C (90°F) at Hongqiao, with Pudong likely mirroring these humid, cloudy conditions that typically cap peak temperatures below the 35°C threshold seen in clear-sky scenarios [5][8]. While the consensus leans contrarian toward lower highs due to expected precipitation, the value spot lies in the 30–34°C range, where historical frequency and the current 32°C forecast align, offering a stark contrast to the market’s current 0% pricing on any viable outcome.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
