Highest temperature in Shanghai on July 11?

Platform comparison

Market context

Shanghai’s July climate is defined by intense heat and humidity, with daytime highs routinely exceeding 30°C and frequently breaching 35°C. Historical data for mid-July at Shanghai Pudong International Airport shows average highs near 30.7°C, while recent years have recorded peaks as high as 38°C, making a sub-30°C maximum exceptionally unlikely [3][6][9]. The current 0% crowd-implied probability for any outcome below typical summer ranges aligns with this established thermal baseline, where temperatures rarely dip below 26°C even at night [6].

Traders should monitor real-time meteorological updates from Wunderground as the settlement window closes, particularly for sudden shifts in cloud cover or precipitation that could temporarily suppress peak temperatures. While long-range forecasts for 11 July 2026 remain uncertain, current models indicate partly cloudy conditions with a maximum near 30°C and minimal precipitation, suggesting no immediate cooling catalyst [4][10]. Any deviation from the expected 30–35°C range would likely stem from an unforecasted rain event or anomalous wind pattern, both of which are rare in Shanghai’s stable mid-summer regime [1][3].

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.
