Highest temperature in Beijing on June 28?

Platform comparison

Market context

The real-world event hinges on the peak temperature recorded at Beijing Capital International Airport on 28 June 2026, measured in degrees Celsius. Historical data for Beijing in June shows daily highs typically climbing above 30°C, with roughly ten days per month reaching 35°C or higher[2]. Extreme outliers have occurred, such as the 41.1°C record set in June 2023, which shattered the previous 60-year benchmark for the city’s hottest June day[3][9]. Given that the current crowd-implied probability for a “YES” outcome sits at 0%, the market appears to be pricing in a scenario where temperatures remain well below the threshold required for a positive resolution, despite the region’s propensity for blistering heatwaves[1].

Traders should monitor official meteorological announcements and heatwave schedules, as dependencies on atmospheric pressure systems can trigger rapid temperature spikes. Recent coverage from Reuters highlights how Beijing has braced for returning heatwaves, with temperatures soaring past 41°C during similar periods in 2023[3]. The book depth for this market is directly tied to funding flows; as deposit friction decreases via seamless on-ramps like Klarna and SEPA, liquidity increases, allowing traders to better position against these weather catalysts. Withdrawal rails such as USDC further incentivise capital retention, ensuring that the market’s volume reflects genuine sentiment rather than speculative noise driven by payment barriers.
