Highest temperature in Beijing on July 10?

Platform comparison

Market context

The underlying event is the peak daily temperature at Beijing Capital International Airport on 10 July 2026, a date that historically sits within the city’s hottest and most humid month. Current market odds imply a 99% probability that the temperature will fall within the expected range, a figure that aligns closely with sportsbook lines but slightly exceeds the conservative analyst consensus, which often accounts for rare micro-climate deviations.

Historical data frames this high probability with strong precedent: July is Beijing’s hottest month, with daily highs averaging 31°C (88°F) and rarely dipping below 26°C (78°F)[3]. The city has recorded extremes of 40°C in 2023 and 41.1°C on its second-hottest day, while the all-time peak of 41.9°C occurred on 24 July 1999[1][2][9]. These records confirm that temperatures consistently reach the upper bounds of the predicted range, making the 99% YES probability statistically robust.

Traders should monitor the National Meteorological Centre’s weekly heatwave forecasts and any sudden shifts in the East Asian monsoon, which can alter humidity and temperature spikes. Recent reports from Asia News Network highlight that China experienced its hottest July on record in 2024, with average temperatures over 5°C above the previous benchmark, suggesting a trend toward more extreme heat[5][8]. With settlement ending 12:00 UTC on 10 July 2026, real-time Wunderground data will be the definitive resolution source, so traders must watch for any last-minute weather model updates that could signal a deviation from the norm.

FAQ

Where can I trade this market with the lowest fees?

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
