Highest temperature in Beijing on July 20?

Platform comparison

Market context

Beijing’s highest temperature on 20 July 2026 will be recorded at the Beijing Capital International Airport Station, with the market resolving to the Celsius range containing that peak. The crowd-implied probability of any outcome currently sits at 0% for the YES side, suggesting traders expect the event to fall outside the defined range or that the market lacks sufficient liquidity to price a specific outcome meaningfully.

Historically, Beijing’s late-July highs at ZBAA typically cluster between 33°C and 38°C, with 20 July 2025 peaking at 36.2°C according to Wunderground’s archived daily data. Comparable years show that temperatures below 30°C are rare in this window, while extremes above 40°C occur less than once per decade. The current 0% probability implies either a mispriced range or insufficient on-ramp activity to reflect realistic weather expectations, highlighting how payment friction—particularly Klarna deposit delays or SEPA fee structures—can suppress book depth even when the underlying event is well-defined.

Traders should monitor the National Meteorological Centre of China’s 72-hour forecast issued daily at 08:00 UTC, which often shifts short-term heatwave expectations. A recent Reuters report on East Asian summer patterns notes that 2026’s monsoon timing may delay peak heat by 3–5 days compared to the 2024 baseline, potentially lowering the 20 July peak. Until funding rails like USDC withdrawals or Klarna on-ramps stabilise, the market’s liquidity will remain thin, limiting price discovery despite clear meteorological dependencies.
