Highest temperature in Beijing on July 22?

Platform comparison

Market context

Beijing’s weather on 22 July is typically a hot, humid midsummer set-up, but the settlement here is the *daily high at Beijing Capital International Airport*, not the citywide forecast. July averages in Beijing usually sit in the low 20s to low 30s Celsius, and the month is also among the wettest of the year, which makes cloud cover and showers key to whether the airport high lands at the top or bottom of the expected range.[3]

The current 0% implied chance for “YES” is only useful if the market’s threshold is set well above the sort of readings Beijing commonly posts in late July. Comparable temperature ranges suggest that highs around 25–31°C are routine, while airport-specific forecasts can run cooler than central Beijing when wind, rain, or cloud suppress daytime warming.[3][4] That makes the market most sensitive to whether the day turns into a dry, sunny heating event or a damp, overcast one with limited upside.

For traders, the main catalysts are the official airport observations through the day, plus any updated forecasts from major weather services as the afternoon heating window develops. Current conditions show Beijing already warm and humid, with cloud cover and light winds, which matters because persistent cloud or rain would cap the maximum temperature at the airport site.[2][4] The final print will come from the Wunderground history page for the airport station, so late-day adjustments to hourly forecasts and precipitation timing are the relevant dependencies.[3][4]
