Highest temperature in Shanghai on August 19?

Platform comparison

Market context

Shanghai's August temperatures are reliably hot and humid, with the city's summer monsoon season typically producing daily highs between 32–35°C. The settlement window closes at midday on 19 August 2026, meaning the market resolves on the highest temperature recorded at Shanghai Pudong International Airport Station up to that point, using the granular Daily Observations table rather than summary figures.

Historical August data from Shanghai shows consistent patterns: the past decade's August averages hover around 32–33°C for daily highs, though peaks occasionally exceed 35°C during particularly intense heat waves. The 2013 and 2017 summers saw several days above 36°C, whilst cooler Augusts have remained in the 30–32°C range. These precedents establish the likely resolution bands; temperatures below 30°C are exceptionally rare for mid-August in Shanghai, whilst readings above 37°C occur only during severe heat events.

Traders should monitor China's meteorological forecasts and any El Niño or La Niña patterns affecting East Asian summer weather in the months preceding August 2026. Urban heat island effects around the airport station can amplify readings compared to surrounding areas, particularly on clear, windless days. The specific reliance on Weather Underground's Daily Observations table—rather than alternative sources or summary sections—means familiarity with that platform's data collection methodology at Pudong station is essential for accurate settlement interpretation.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

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.
