Highest temperature in Seoul (Incheon) on September 11?

What this question means

A further two days on from its counterpart on this board, and the picture has softened: 25°C at 44%, 26°C at 26%, 24°C at 21%, then 27°C at 6% and 23°C at 5%.

The 9 September question on the same station peaks a degree warmer at 48%. So the crowd expects slight cooling and holds that view with slightly less conviction — both of which are what you would expect from a forecast reaching further out.

What is notable is how modest the changes are. One degree of cooling and four points of confidence across two days is a gentle drift, not a weather event. Compare with Ankara on this board, where three days brings five degrees of change, or London, where a front cuts four degrees in two days.

Coastal locations at mid-latitudes sit between those extremes: enough maritime influence to damp the swings, enough seasonal movement to prevent the near-total stability of the tropics.
