Pronóstico: Highest temperature in Shanghai on July 27?

Platform comparison

Market context

Shanghai’s 27 July reading at Pudong is usually decided by a hot, humid summer pattern rather than a dramatic one-day swing. July is typically Shanghai’s rainiest and hottest month, with average highs around 32°C and occasional extremes reaching 40°C, so the market is really about where the day lands inside that broad seasonal band rather than whether it turns warm at all.[2][3]

That said, the current crowd-implied **0% YES** looks detached from the climate profile: current weather feeds already show Shanghai in the low-to-mid 30s Celsius, with one live forecast at 37°C and another current observation at 22°C, underlining how much the day’s outcome depends on which part of the city and which part of the day the station captures.[1][4] For a station-based settlement, comparable July cases matter more than city averages, because a short-lived thunderstorm, marine breeze, or cloud cover can cap the daily maximum even when the month is broadly oppressive.[3][6]

Traders should watch the official Pudong airport observation flow through the day, especially the timing of early-afternoon heating and any rain bands that move in before the daily high is locked in. The market resolves to the highest temperature recorded at Shanghai Pudong International Airport Station on 27 July via Wunderground, so late updates, forecast revisions, and any change in local cloud cover or rainfall will matter more than general Shanghai forecasts.[3][6]
