Highest temperature in Beijing on July 14?

Platform comparison

Market context

On 14 July 2026, the highest temperature recorded at Beijing Capital International Airport will fall into one of several defined ranges. The Polymarket contract currently prices all temperature brackets at 0% probability, reflecting either sparse liquidity or settlement mechanics that have not yet attracted substantive trading activity. This represents a straightforward weather measurement event with a fixed resolution date and a single authoritative data source via Wunderground's historical records for the ZBAA station.

Beijing's July climate is consistently hot and humid, with historical highs typically ranging between 32–35°C during mid-summer. The city's 30-year average maximum temperature for mid-July sits around 32.5°C, though extremes have reached 40°C during exceptional heatwaves. Recent summers have shown increasing volatility; July 2022 saw temperatures exceed 35°C on multiple days, whilst 2023 remained closer to historical norms. These patterns suggest the market's temperature brackets should cluster around the 32–36°C range, with lower probability assigned to outlier scenarios above 37°C or below 30°C.

Traders monitoring this contract should track China's meteorological forecasts released in early July 2026, particularly any alerts from the China Meteorological Administration regarding heat warnings or anomalous pressure systems. The East Asian summer monsoon's strength in early July will be the primary driver of whether the capital experiences typical seasonal heat or an intensified heatwave. Additionally, any significant weather pattern shifts—such as tropical cyclone activity in the Western Pacific—could redirect moisture and wind patterns toward Beijing, potentially moderating temperatures. Settlement occurs at 12:00 UTC on 14 July, aligning with the calendar date in Beijing local time.
