Korea Weather in April
Like all shoulder months, the Korea weather in April has a little bit of everything. This is a transition month from winter to spring, so while daytime temperatures get increasingly comfortable, it’s still relatively chilly in the evenings, and can be downright cold at night. Especially at the beginning of the month.
In April, average daily temperatures in Korea range from 7 to 18°C across the country. Towards the end of the month, there can be days that reach into the low 20s. There’s little humidity, but you can expect some rainfall. Keep in mind that it can still get quite cold in the evenings, with temperatures falling as low as 5°C.
Seoul Weather In April | Temperature & Climate
Seoul in April, has average temperatures of 7 to 18°C. Climate wise, it’s one of the most pleasant times of the year to visit the mega-city. Daylight hours increase to 13, and there’s quite a bit of sunshine and blue sky during the day.
The Seoul weather in April has low humidity, but there are about 5 days of rain, totalling approximately 65mm, on average. It gets progressively warmer over the course of the month, but keep in mind that it’s still quite chilly at night. You’ll definitely need a jacket in the evenings.
Is the Seoul weather in April cold?
This is subjective. If you’re traveling from Southeast Asia or other tropical climates, you would probably find Seoul in April to be quite cold, especially at night. If you were raised somewhere like Canada, you’d find this month to be extremely comfortable, weather wise (like I do).
Busan Weather in April | Temperature & Climate
Busan is located on the southern part of the Peninsula, so you can expect it to be a couple of degrees warmer than Seoul. It has average temperatures of 10 – 18°C. The sea temperature hovers around 15°C, so I definitely wouldn’t plan on swimming in April.

Sokcho Weather in April | Temperature & Climate
Korea’s East Coast tends to be a bit cooler than the interior. In Sokcho in April, average daily temperatures range from 7 – 16°C. In my experience, it can feel quite chilly, even in summer, so plan accordingly. In fact, we took a trip to Jeongjongjin Beach in July one year, and it was so cold and windy, it was impossible to go swimming!
Jeju Weather in April | Temperature & Climate
Jeju is known as the “Hawaii of Korea,” but in April, temperatures are not much different than in Seoul. Averages range from 10 – 16°C, with 8 days of rain. Jeju is notorious for wind, so be sure to bring a warm jacket or windbreaker if you plan to visit.
Korea Weather in April | Air Quality
The one downside to traveling to Korea in April, might be the air quality. In spring, windstorms originating in the Gobi Desert, travel across China, and land squarely on top of Korea in the form of yellow dust. This “hwangsa” colours the sky, with a grainy, yellowish cast. And unfortunately, it’s full of ultrafine and fine dust pollution.
It’s not just ugly, it can also be incredibly harmful to your health. If you’re visiting Korea in April, be sure to equip yourself with some kind of air pollution mask.
Those rated N95 or N99 are the best, since they filter out almost 100% of pollutants. There’s no need to prepare something in advance. You can pick up disposable air pollution masks in any pharmacy, convenience store or Daiso in Korea for just a few thousand won.
If you’d like something washable and reusable, I recommend the Vogmask. This is what our family uses, and they’re super comfortable and rated N99. They even have small sizes and cute designs for children.
What to wear for the Korea weather in April
To best deal with the Korea weather in April, layers are the name of the game. Jeans, trousers, skirts with leggings or tights, and long-sleeved shirts or sweaters work well. Bring along a hoodie, cardigan or light jacket, in case the wind starts up, or there’s a brief cold snap.
There is some precipitation in April, but rather than carry a cumbersome umbrella with you everywhere you go, I recommend picking one up on the fly at a convenience store or street stall, if it starts to rain. Umbrellas will pop up every which way you turn, as soon as the drops start falling.
NEED A RAIL PASS?
A KR Rail Pass is one of the best ways to travel around Korea. Make your trip a total breeze with access to 600 stations, 80 routes and all types of trains, including the KTX high speed rail. Choose between unlimited rides on 3-5 consecutive days, or Flexible 2 or 4 day passes for total worry-free travel around the country.
