Highest temperature in Beijing on September 11?

What this question means

Beijing on 11 September peaks at 31°C with 54%, then 32°C at 28%, 33°C at 10%, 30°C at 7%, 29°C at 3% and thinner values below.

Look at the shape rather than the peak. The warm side carries considerably more weight than the cool side — 38% above the peak against 13% below it. That asymmetry is the informative part, and it is easy to miss if you only read the leading number.

Skewed distributions usually indicate a directional risk. Here it suggests conditions where an unusually warm day is more plausible than an unusually cool one, which is typical of a continental climate in early autumn, when a lingering summer pattern can push temperatures up more readily than an early cold front pulls them down.

Reading skew is a habit worth building. Two distributions with the same peak and the same spread can imply quite different things depending on which side the weight sits.
