Highest temperature in Shanghai on July 14?

Platform comparison

Market context

Shanghai's peak temperature on 14 July 2026 will be measured at Pudong International Airport Station and resolved against historical weather data. The crowd is pricing this at 0% YES, suggesting either extreme confidence in a specific temperature range or minimal trading activity. July sits firmly within Shanghai's summer monsoon season, when daily highs routinely exceed 32°C and frequently reach 35–37°C under typical atmospheric conditions.

Historical records show Shanghai's July temperatures cluster heavily in the 33–36°C band, with occasional spikes above 37°C during heat waves. The 0% probability across all ranges signals either a market structure issue or that traders have not yet engaged with this particular settlement window. Comparable July days at Pudong typically see highs between 34–35°C under normal circulation patterns, though the 2013 heat wave pushed readings to 38.5°C and the 2022 summer saw multiple days above 37°C. The current pricing reflects no consensus whatsoever rather than genuine conviction about the weather outcome.

Traders should monitor late-June atmospheric patterns and any developing Pacific typhoon activity, which can suppress temperatures or drive them higher depending on timing and track. The China Meteorological Administration issues seasonal outlooks in early July that often influence medium-range forecasts. Any significant heat dome formation across East Asia in early July would be the primary catalyst shifting probabilities, as would tropical cyclone positioning in the weeks preceding the settlement date. Standard seasonal heating patterns favour ranges in the 34–36°C band based on recent decades of data.
