Seoul isn’t one of those places where “any time is a good time.” The season you go really changes how the trip feels. Summer in Seoul gets hot and sticky, and winter is properly cold. Spring and autumn are usually the sweet spot if you want milder temps and time outdoors. The point is: walking around, sightseeing, and even just grabbing a meal can feel very different depending on when you go.
I’ve only been to Seoul in spring, and that was completely on purpose. I’m obsessed with cherry blossoms, so that was always going to be my season. It was beautiful, and I loved it — and honestly, that trip got me curious about South Korea in general and all the surprising things I hadn’t known before I went.
That said, one trip in one season doesn’t give you the full picture. So I reached out to Jimmy and Tah, who’ve visited Seoul way more than I have across different months and seasons, to help figure out when’s really the best time to go.
Whatever your priorities, whether it’s weather, budget, festivals, or avoiding crowds, this guide breaks down what to expect in each season. Some months are more comfortable, some are cheaper, and some are just nicer to be outside in. It really depends on what matters most to you, especially if you’re thinking about spending a couple of days in the capital.

Spring in Seoul (March – June)
Spring in Seoul begins in mid-March and continues through June. It’s often considered a shoulder season, with mostly mild, pleasant weather. In April, cherry blossoms burst into bloom, covering the city in soft pink. This is when Seoul is at its most photogenic and, for many travelers, its most magical, especially if you know where to go. Here are a few of my favorite cherry blossom spots in Seoul if you’re planning a spring visit.
If you’re up for it, a fun thing to do during cherry blossom season is to rent a hanbok (traditional Korean dress) and walk around the palaces or parks in it. It’s super popular with locals, too, and makes for great photos. This rental shop near Gyeongbokgung is easy to get to.
Temperatures in spring usually range from around 2°C in early March to 28°C by the end of June, warming steadily month by month. Early spring can still feel chilly, so pack warm outer layers. A waterproof jacket is also a good idea for occasional rain. If you’re planning to go hiking, especially in March, bring waterproof hiking shoes. Mount Inwangsan, just on the edge of the city, offers fantastic trails and views.
Spring is also a great time to explore more of South Korea, with other destinations at their best.
Summer in Seoul (July – August)
Summer in Seoul runs from July through August and is considered the peak tourist season. The city sees large crowds during these months—but when it comes to weather, it’s not always the easiest time to visit.
Expect hot, humid days with heavy rainfall, especially during Korea’s monsoon season in July. Temperatures typically range between 18°C and 32°C, with humidity making it feel even hotter. If you don’t mind the heat and occasional downpours, summer can still work—especially if you come prepared. Here are a couple of tips for visiting Seoul in summer to help you handle the weather and still enjoy your trip.
Because it’s high season, flights and hotel prices tend to spike. If you do visit in summer, pack light, breathable clothing like quick-dry tees and travel pants, along with a lightweight rain jacket or umbrella. Sudden downpours are common.
Autumn in Seoul (September – November)
Autumn in Seoul begins in September and runs through November. It’s one of the best seasons to visit thanks to the mild weather, low rainfall, and beautiful fall colors. The air feels crisp, the skies are often clear, and the city parks and mountains turn gold, red, and orange by late October.
Temperatures range from around 26°C in early autumn to as low as 2°C in November, so layering is key. Early autumn can still feel quite warm, while later weeks call for layers, a fleece jacket, and a raincoat for the occasional wet day.
This is also one of the best times of year for hiking—whether you’re doing a trail in Bukhansan or heading out on a day trip from Seoul. Just be sure to pack sturdy walking shoes, especially if you’re going into the mountains.
Winter in Seoul (December – mid-March)
Winter in Seoul lasts from December to mid-March and brings cold weather, with occasional snowfall.
Temperatures typically range from -5 °C to 4°C, and while the city doesn’t get heavy snow every day, you’ll definitely feel the chill. It’s not the most popular time to visit, which means flight and hotel prices are often lower.
To stay warm, pack a hardshell winter jacket, a couple of pairs of gloves, a hat, a scarf, and waterproof boots or shoes. You’ll need proper layers, especially if you’re planning to walk around or spend time outdoors.
Seoul’s palaces and shrines are still worth visiting in winter, just make sure you’re dressed for the cold. Winter’s also a good time to enjoy the local food scene. Korea’s spicy soups and stews, like spicy pork rib stew (maeun galbijjim), spicy seafood noodle soup (jjamppong), and stir-fried fire noodles (buldakbokkeummyeon), are great ways to warm up when it’s freezing outside.
If you’re up for something hands-on, you could also try making a few dishes like bulgogi, gyeran-jjim (steamed eggs), and kimbap in this Korean cooking class. Or, if you’d rather just eat and drink, there’s also a traditional soju and makgeolli tasting that’s a nice way to wind down indoors.

Our Favorite Months
Seoul has four distinct seasons, with hot, humid summers and properly cold winters. Spring and autumn usually offer the most comfortable weather, which is why they’re often considered the best times to visit.
If you’re after a sweet spot where the weather’s good, the scenery’s beautiful, and it’s not too crowded, April and October are two standouts. Here’s why these months are such popular picks.
Why Visit Seoul in April?
April is one of the most beautiful times to visit Seoul. The weather is usually mild, with less rain than in summer, and cherry blossoms are the main attraction. For about two weeks, the city turns pink, especially near palaces, parks, and riversides.
Two of the best places to catch the blossoms are Yeouido Park and Changdeokgung Palace. But if you don’t want to stress about timing or where to go, this cherry blossom tour makes it easy to see some of the most scenic spots in one go.
Just keep in mind that cherry blossom season is busy, so booking your accommodation and tours early is a good idea.
Why Visit Seoul in October?
If cherry blossoms aren’t your thing, October is another great time to visit. The weather cools down after summer, the skies are usually clearer, and the city is full of fall colors, especially in parks and on mountain trails.
If you want to go beyond Seoul, Naejangsan and Seoraksan are two of the most famous national parks in Korea for autumn foliage. While both require a bit of travel, this day tour makes it easy to visit and even includes a stop at Jeonju Hanok Village on some dates.
You’ll want to pack warmer layers, especially for early mornings or evenings. And if your trip lines up with Chuseok, Korea’s mid-autumn harvest festival, it’s a great chance to experience local culture. Just note that some attractions may close for the holidays.
So, When Is the Best Time for You to Visit Seoul?
There’s no single “best” time that works for everyone.
If you want to see cherry blossoms, early April is your best bet. October is ideal if you’re after fall colors. Both months are popular for a reason: they’re not too hot or cold, and they’re usually drier than summer.
But maybe you’re on a tighter budget and looking for lower prices—that’s where late winter or early spring can work well. Want to avoid crowds? Skip peak summer. Planning to hike? Autumn usually has the best conditions. If you’re more interested in food than foliage, winter is a great time to enjoy spicy stews and hearty local dishes.
Whatever kind of trip you’re planning, I hope this guide gave you a better idea of what to expect and helped you choose the season that best suits you.
