Packing for Korea: the four seasons, and what they mean for your bag

Korea is sold on its four seasons and for once the marketing is accurate. The difference between February and August here is larger than most visitors expect, and larger than the difference between the same months in most of Europe or the eastern United States. The mistake in packing for Korea is not underpacking. It is packing for the average of a season instead of what that season actually does.

A note on numbers

We are not printing a table of monthly averages. The Korea Meteorological Administration publishes proper thirty-year climate normals, and a summary table copied from somewhere else and slowly going stale would be worse than sending you to the real thing.

What follows is what the seasons are like to be in, which is the part the averages do not tell you. Today's actual temperature in Seoul is on our front page, updated every morning, and if you are travelling soon that is more useful than any normal.

Winter, December to February

Cold and dry, with the cold coming in waves rather than settling. A run of mild days is routinely followed by a sharp drop, and the wind is what you feel rather than the number.

Pack for wind, not just for cold. A windproof outer layer matters more here than an extra jumper. Koreans wear long padded coats through the worst of it and they are not being dramatic.

Indoors is heated hard, and shops, subways and restaurants are warm enough that a heavy coat becomes a problem the moment you step inside. Layers you can shed beat one thick thing.

Snow happens but Seoul is not buried in it. What ice there is sits on stone steps and palace courtyards, so shoes with some grip earn their place.

Spring, March to May

The best time to be here, and the busiest. Cherry blossom moves up the country from the south over a couple of weeks, and it is brief: a week of full bloom in any one city, ended by the first serious rain.

March is still cold. April is the month people are picturing. May is warm, green and often the most comfortable weather of the year.

Two things to plan around. Fine dust and yellow dust are worst in spring, and on bad days the air quality genuinely affects an outdoor day. Our front page carries the daily reading. The second is that everyone else has also worked out that spring is the good season, so accommodation and intercity transport are tighter than usual.

Summer, June to August

Hot and, more to the point, humid. The temperature is manageable; the humidity is what people find hard.

The rainy season is not a rumour. A stretch of concentrated rain moves across the country in roughly the second half of the monsoon period each year, and its exact timing shifts. It does not rain constantly. It rains hard, stops, and does it again, which is worse for planning than steady drizzle.

Carry a small umbrella from June onward. Convenience stores sell them everywhere for very little, so a forgotten one is a minor problem.

Late August is the peak of the heat and also the peak of air conditioning, which is set aggressively. A light long-sleeved layer for indoors is the thing visitors most often wish they had brought in August, which sounds absurd until you sit in a Korean cafe in summer.

Autumn, September to November

The other good season, and the one to choose if you dislike crowds more than you like blossom.

September can still be hot and carries the tail of the typhoon season, which for a traveller usually means a couple of wet days rather than anything dramatic. October is close to perfect: dry, clear, mild, and the best light of the year. Foliage moves down the country from the north through late October and November, the reverse of the blossom.

November turns cold quickly at the end. A trip that starts in mild autumn can finish in a coat.

The packing rule

Bring layers and one good outer shell, in every season. Korea's indoor and outdoor climates are further apart than most countries', in both directions: heated hard in winter, chilled hard in summer. The visitor who is comfortable is the one who can add and remove a layer in thirty seconds.

Everything else you can buy here, cheaply and at any hour. Umbrellas, socks, a scarf, a T-shirt when it turns out warmer than you thought. That is what the convenience store and the shopping districts are for.

Quick answers: packing for Korea

What is the best month to visit Korea?

April and May for blossom and comfortable weather, October for dry, clear days and autumn colour. Spring is the busiest season and has the worst fine dust; autumn is the one to choose if you dislike crowds.

When is the rainy season in Korea?

A stretch of concentrated rain moves across the country in the second half of the monsoon period, broadly late June into July, with timing that shifts each year. It rains hard, stops, and does it again. Carry a small umbrella from June onward.

What should I pack for Korea in winter?

A windproof outer layer over layers you can shed. Indoors is heated hard, so a single heavy coat becomes a problem the moment you step inside. Shoes with grip for icy stone steps.

Is Seoul humid in summer?

Very. The temperature is manageable; the humidity is what people find hard, and August is the peak. Air conditioning is set aggressively, so bring a light long-sleeved layer for indoors.
