Highest temperature in Shanghai on August 13?

Platform comparison

Market context

Shanghai's highest temperature on 13 August 2026 will be recorded at Pudong International Airport Station and resolved against the Daily Observations table on Weather Underground. The settlement window closes at midday UTC on that date, meaning traders will have access to the full day's temperature readings before final resolution.

August is Shanghai's hottest month, with historical daily highs typically ranging between 32 and 35 degrees Celsius. Data from the past decade shows that extreme heat events pushing above 37 degrees occur roughly once every two to three years during mid-August, whilst temperatures below 30 degrees are exceptionally rare. The current crowd probability of 0% suggests traders are pricing in a specific temperature threshold that historical patterns indicate is either unusually high or represents an outlier scenario. Comparison with August 2023, when Shanghai recorded a peak of 40.9 degrees, and August 2013, which saw sustained highs above 35 degrees, provides context for evaluating the market's implied range.

Traders should monitor meteorological forecasts released in early August 2026, particularly from China's National Meteorological Centre, which publishes extended outlooks approximately two weeks in advance. Tropical cyclone activity in the Western Pacific during late July and early August can significantly alter Shanghai's weather patterns, either suppressing temperatures through cloud cover and precipitation or intensifying heat through atmospheric pressure systems. The specific resolution methodology—using Weather Underground's Daily Observations table rather than summary figures—means traders must verify the exact data source and station readings rather than relying on commonly cited temperature reports.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
