Pronóstico: Highest temperature in Shanghai on July 14?

Platform comparison

Market context

Shanghai's summer heat peaks in mid-July, when the city's subtropical climate typically produces daily highs between 32–35°C. The settlement hinges on the single highest temperature recorded at Pudong International Airport on 14 July 2026, resolved against Wunderground's historical data. Polymarket currently prices this contract at 0% YES across all temperature bands, reflecting either extreme illiquidity or a technical artefact in how the market initialised its outcome ranges.

Historical July records at Shanghai Pudong show temperatures regularly exceed 35°C during the second fortnight of the month. The city's 30-year average high for mid-July sits around 32–33°C, though heat waves have driven readings above 37°C in recent years. The 2022 summer saw Shanghai endure a prolonged heatwave with multiple days above 38°C; conversely, cooler-than-normal Julys have still produced highs in the 30–32°C range. These precedents suggest the true probability mass lies in the 32–36°C bands rather than extreme outliers.

Traders should monitor China's meteorological forecasts released in early July 2026, which typically provide 10-day outlooks with reasonable accuracy for temperature ranges. The East Asian summer monsoon pattern—whether it delivers wet, cooler air masses or stalls over the region—will be the primary driver of Shanghai's conditions that week. Any significant atmospheric blocking pattern or tropical cyclone activity in the Western Pacific could shift outcomes materially, though such events remain inherently difficult to predict six months ahead.
