Pronóstico: Highest temperature in Shanghai on August 11?

Platform comparison

Market context

Shanghai's highest temperature on 11 August 2026 will be measured at Pudong International Airport Station and recorded in Weather Underground's Daily Observations table. August is Shanghai's peak summer month, with typical daily highs ranging from 32–34°C, though extreme heat events occasionally push readings above 36°C. The specific resolution methodology—prioritising the Daily Observations table over summary figures—matters because discrepancies between data sources can shift outcomes across temperature bands.

Historical August data from Shanghai shows considerable year-to-year variation. The city has recorded temperatures exceeding 37°C on multiple occasions during August in recent decades, whilst cooler years see highs stabilise around 31–32°C. The 0% crowd probability suggests traders are either heavily positioned against extreme heat or the market's current range brackets don't capture the expected outcome. August 2026 falls within a period when long-range forecasting models typically show moderate confidence; seasonal patterns favour above-normal temperatures given the month's climatology, but individual day forecasts remain uncertain until closer to the date.

Traders should monitor tropical cyclone activity in the Western Pacific during early August, as storm systems can suppress temperatures significantly. Additionally, the El Niño/La Niña phase in mid-2026 will influence regional atmospheric patterns. Weather Underground's station data quality and any potential maintenance windows at Pudong Airport should be tracked, as these could affect measurement continuity. Current seasonal outlooks from meteorological services will become more precise by July 2026.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

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.
