Highest temperature in Shanghai on August 2?

Platform comparison

Market context

Shanghai’s outcome will be set by the day’s peak temperature at Pudong, and the market is really a bet on whether heat can build far enough for the airport reading to clear the lower August bands. Shanghai is normally hottest in August, with typical highs around the low- to mid-30s Celsius, but daily extremes still vary materially with cloud cover, rain, and marine air. Historical August data show average highs of about 32.5°C and a long-run record high near 40.0°C, so a 0% crowd price leaves the market treating a meaningful heat spike as highly unlikely rather than impossible.[5][6][8]

Comparable August cases matter because Shanghai can run very hot for sustained stretches when the city is under a persistent heat dome, but the airport reading can be capped if showers, haze, or onshore flow intrude. In 2025, Shanghai saw a record-setting August heat spell with a 35.8°C downtown high late in the month and 26 consecutive high-temperature days, showing how quickly the city can shift into extreme heat once conditions lock in.[3] Against that backdrop, the current price is best read as a statement that traders see little evidence, at least so far, of a comparable August 2 surge developing around Pudong.[3]

The main catalysts are the same ones that move the intraday high: official Shanghai and national weather updates, typhoon tracking in the western Pacific, and any forecast revisions that change cloud, rain, or wind expectations over the airport. Forecast services for early August point to highs in the high-20s to low-30s Celsius, with some outlooks showing a warmer start to the month but little signal yet of a breakout heat event.[13][17] For traders, the key dependency is whether morning convection or a passing rain band suppresses the afternoon maximum at Pudong before the settlement window closes.[13][17]

FAQ
