A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

The year in Seoul
Seoul's climate features cold winters and hot, humid summers. Be aware that the wet season from July to August can include heavy rain, and extreme heat may occur during this time.
| Busiest |
early Apr to late Jun — Spring is a popular time due to cherry blossom festivals and mild weather.
early Sep to late Oct — Autumn features beautiful foliage and comfortable temperatures, attracting many visitors.
|
|---|---|
| Quieter, still good |
early Jan to late Feb — Winter is quieter, offering better prices despite cold temperatures.
early Nov to late Mar — Late fall to early spring sees fewer tourists, resulting in lower accommodation rates.
|
| Wet or stormy |
early Jul to late Aug — monsoon, moderate
|
| Watch out for | extreme heat; haze |
This section was written by a language model from the climate figures above, and nobody has checked it. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe. The busiest and quieter periods here also count toward the crowd score, which is 20% of the ranking.
