Highest temperature in Shanghai on July 28?

Platform comparison

Market context

Shanghai's summer temperatures in late July routinely exceed 35°C, with the city's humid subtropical climate producing some of the year's most intense heat. The highest temperature recorded on 28 July will be measured at Pudong International Airport Station, the official meteorological reference point, and resolved via Wunderground's historical weather database. July typically ranks among Shanghai's hottest months, with average highs around 32–33°C, though peak readings frequently climb into the 37–39°C range during heat waves.

Historical precedent from Shanghai's weather records shows considerable year-to-year variation in late-July extremes. The city experienced a notable heat wave in July 2022 with temperatures exceeding 40°C on multiple days, whilst other years have seen more moderate peaks in the 34–36°C band. Wunderground's historical archive provides consistent daily maxima across decades, allowing traders to calibrate expectations against comparable dates and seasonal patterns. The 0% crowd probability suggests either extreme confidence in a specific temperature range or sparse trading activity on this particular outcome.

Traders should monitor Shanghai's weather forecasts from mid-July onward, particularly any alerts issued by China's meteorological authority regarding heat waves or unusual atmospheric patterns. The East Asian monsoon system and any tropical systems developing in the Western Pacific could influence conditions in the final week of July. Settlement occurs at noon UTC on 28 July, aligning with the airport station's daily maximum recording window, leaving no room for late-day surprises to affect the outcome.

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

When do award markets resolve?

After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.
