Pronóstico: Highest temperature in Shanghai on July 18?

Platform comparison

Market context

Shanghai's weather on 18 July 2026 will be measured against historical July temperatures at Pudong International Airport, the official settlement source. Mid-July sits within Shanghai's peak summer season, when daily highs typically range between 32–35°C, though extreme heat events can push readings above 37°C. The 0% crowd probability suggests traders are either uncertain about the specific temperature bands available or treating this as a calibration exercise rather than a genuine forecast opportunity.

Shanghai's July climate is shaped by the East Asian summer monsoon and occasional tropical systems. Historical records show considerable year-to-year variation: 18 July 2015 recorded 34.1°C, whilst 18 July 2019 reached 32.8°C. The city experiences occasional heat waves in mid-summer, particularly when high-pressure systems stall over eastern China, though such events are not guaranteed annually. Comparing adjacent dates provides useful anchoring—16 July 2023 peaked at 35.2°C, whilst 20 July 2023 reached 34.6°C.

Traders should monitor China Meteorological Administration forecasts released in the week preceding settlement, which typically provide 7–10 day outlooks with reasonable accuracy for temperature ranges. Any tropical cyclone activity in the Western Pacific during early-to-mid July could alter atmospheric patterns significantly, either suppressing temperatures through cloud cover or intensifying heat through pressure redistribution. The settlement window closes at midday UTC on 18 July, meaning the final recorded high will reflect morning and early-afternoon readings only, not any potential evening cooling.

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
