What is the best time to visit Jeju? A guide to the four seasons

You’re sure to find something fun to do at any time of year.

Jeju (and Korea in general) has four distinct seasons. This means the weather can be drastically different depending on when you visit the island. This will impact the type of trip you have, so it’s important to visit the island at a time that fits in with your planned activities.

The good news is that you’ll find plenty to do no matter what time of year you visit. Here is a guide to the island’s seasons so you can decide exactly when is the best time to visit Jeju Island for your needs.

Spring in Jeju

Spring, meaning any time from March to May, is a beautiful time to visit the island. At the start of spring the weather is just beginning to heat up, while by May the temperature will regularly exceed 20°C.

At this time of year, the island starts to regain the color it lost during winter. This starts with the arrival of pink cherry blossom towards the end of March, and you’ll also see plenty of fields of bright yellow canola flowers.

All this means that spring is the best time of year to visit Jeju Island if you enjoy outdoor activities. You can hike the island’s oreum or Olle Trails, spend time visiting attractions like the waterfalls or beaches, or simply walk around the city without worrying about it being too hot or cold.

Spring highlights 🌸

  • View the island’s cherry blossom at the end of March or early April
  • Visit fields of Yellow canola flowers around Sanbangsan Mountain or Seongsan Ilchulbong Peak
  • Take in Jeju’s coast via one of the Olle Trials that circumnavigate the island

Spring Average Temperature

March: High 12°C/5°C Low

April: High 17°C/9°C Low

May: High 21°C/13°C Low

Summer in Jeju

Summer in Jeju, meaning any time from June to August, is when the weather really starts to heat up. June is typically bearable, but temperatures in mid-July to mid-August can be hot and humid.

Temperatures during this period regularly hit 30°C and July and August are the hottest months of the year on Jeju. There’s also typically more rain at this time of year, with June getting an average of 12 days of rain and July and August getting an average of 11. There is also a risk of typhoons hitting, especially towards the end of August.

Summer is the time to visit Jeju if you want to hit the beach. The beach facilities are open, meaning you’ll get showers and lifeguards at most of the island’s most popular coastal spots. There may also be more food sellers, creating a festival-like atmosphere.

Another good reason to come to the island during the summer is that the days are longer. At the peak of summer, the sun rises at around 5.30 a.m. and doesn’t set until around 7.45. p.m. This gives you maximum time to explore the island in the daylight.

Summer highlights 🏖️

  • Head to one of Jeju’s best beaches and go for a swim in the sea
  • Stay at a resort with an outdoor pool to cool down
  • Go for a shaded forest hike to stay cool(ish) while keeping active

Summer average temperatures

June: High 24°C/18°C Low

July: High 29°C/23°C Low

August: High 29°C/23°C Low

Fall in Jeju

The fall months between September and November are a special time to visit the island. But like spring, your trip will depend on the precise time during the season that you come.

The weather in September in Jeju is hot, albeit cooler than in the summer months. By November, there are days at the end of the month when it feels noticeably colder, although still some days where the temperature will hit 20 degrees and over.

Like spring, fall is a great time to visit the island to enjoy its nature. Cycling around the island, hiking in the fall foliage, and forest walks are popular at this time of year. Fall is also a good time for runners, with the island hosting marathons, ultramarathons, and shorter runs during this period.

The end of the season is also a good time to see one of the most quintessentially Jeju sights: fields of orange trees with the brightly-colored fruits in full bloom. These typically start to appear in November. Fields of silver grass swaying in the wind is a another natural sight to look out for at this time of year.

Fall is also the time of year of Chuseok, one of the two major Korean holidays, which typically falls at some time in September or October. This means two things for travelers: there will be a day when fewer businesses will be open than usual, and the island will be extremely busy during the period of the holiday.

Fall highlights 🍂

  • View the changing colors of the fall foliage at Cheona Valley forest path or on Hallasan Mountain
  • Take in the views of silver grass at Saebyeol Oreum
  • Cycle on one of Jeju’s coastal cycle paths

Fall average temperatures

September: High 25°C/19°C Low

October: High 21°C/14°C Low

November: High 16°C/8°C Low

Winter in Jeju

Winter is undoubtedly the coldest time of year on the island. But, Jeju’s humid subtropical climate means it is actually much warmer than Seoul–the island’s coastal regions rarely go below 0°C. Catch the island on a good day when the sun is shining and the air is still, and it may even feel warm.

Winter is also the time of the year that the upper regions of Hallasan Mountain become covered in snow. The summit is snow-capped for pretty much the entire winter period. Not only does this provide some beautiful views, but it’s also a good chance for a hike in the snow. It’s a manageable hike as long as you have the correct equipment and some crampons.

If you want to experience the snow without climbing up the mountain, there’s still a good chance of getting snow in the higher regions you can drive to, such as the 1100 Rest Area, which at 1,100 meters above sea level, is the highest road on the island. There are days when it snows in the lower regions, although these are few and far between.
