Highest temperature in Shanghai on July 7?

Platform comparison

Market context

The real-world event at stake is the peak temperature recorded on 7 July 2026 at Shanghai Pudong International Airport, a date that historically sits within the city’s hottest and most humid period. Long-term averages for early July show daily highs typically climbing between 34°C and 35°C, with frequent spikes to 36°C or higher under clear skies and strong solar radiation. In 2025, the airport reached 38°C, confirming that extremes above 35°C are not anomalies but expected outcomes in this climatic window.

Current crowd-implied probability of 0% YES on the prediction market starkly diverges from trader consensus on Polymarket, where 36°C leads at 36% and 35°C follows at 27%, suggesting a collective view that temperatures will exceed 34°C. This 0% figure implies either a mispriced contract or a misunderstanding of the underlying range, as historical data and analyst models consistently place the peak in the 34–36°C band. Traders should monitor real-time weather updates from Wunderground and local forecasts from AccuWeather, which currently project highs between 86°F and 100°F (30–38°C) for July 2026, reinforcing the likelihood of a high-temperature outcome. No major weather announcements are scheduled, but the dependency on clear skies and minimal cloud cover remains critical for peak heat development.
