June is the first of the official summer months in South Korea. Although the beginning of the month can bring with it cool mornings and evenings, most of June is warm and humid. Plenty of rainfall can be expected no matter where you are in the peninsula. June temperatures in the country range from a maximum low of 10°C (50°F) to a maximum high of 28°C (82°F).
June is busy without being overly crowded. The latter half of summer is more crowded. Prices for most things including dining, accommodation, entertainment, and transportation remain modest during June but it's wise to plan and book things in advance.
While you may need a light jacket during the early mornings or late evenings depending on which part of the country you find yourself in, it remains largely warm and humid in most parts of the country during June. As such, we recommend including clothing items made of soft, breathable, fabrics like cotton or linen. Summer dresses, cotton or linen shorts and tops, a pair of comfortable walking shoes, sunglasses, a sunhat, sunscreen, an umbrella for the unavoidable rainy days, and swimwear for your June packing list for South Korea.

Best Places to Visit in South Korea in June
1. Busan
Humidity can touch the 80% mark in the seaside city of Busan in June, but that being said, it's not as sticky and miserable as you might expect. The fresh sea breeze, a mainstay of the June weather in the city, means there's plenty of respite available from the rather high levels of humidity.
It's not as crowded in Busan during June either, meaning you can relax on one of the city's many pristine beaches before it gets busier towards the second half of summer.
2. Seoul
Seoul provides for the perfect starting point for your trip to South Korea. The capital is home to the ancient royal palace, Gyeongbokgung and the Gwangjang Food Market. The city also provides good access to the DMZ, or the Demilitarized Zone shared between the two Koreas, and plays host to some of the world's best music festivals during the month of June.
It is, however, warm and rainy in Seoul during June, so it's best to carry good sunscreen and a trusted umbrella with you at all times.
3. Jeju Island
Jeju Island, located on the extreme southern end of the country, plays host to some of the best weather conditions of any place in South Korea during the month of June. Although the waters are still a little too cold for you to take a dip, enjoying scrumptious seafood as you sit and relax on the beach is certainly the way to go.
It's important to note, though, that Jeju often experiences summer typhoons. As such, do be sure to consult national weather reports before booking any trips to the island.
June Crowds and Costs
June marks the beginning of the summer season in South Korea but that being said, it's not as crowded in the country in June as it is during the months that follow. Popular tourist attractions, restaurants, and beaches will all remain busy without being overly crowded.
Prices for everything including transportation, accommodation, entertainment and dining will have gone up from the preceding months of spring but they're still moderately reasonable compared to the hike that will be observed during July and August.
For the best prices, especially in accommodation and transportation, we recommend you make your bookings as far in advance as possible.

This is a huge event in the world of electronic music, meaning you should buy your tickets as soon as possible if you don't wish to be disappointed.

What to Wear in South Korea in June
The weather will change significantly throughout the entirety of June in South Korea. During the beginning of the month, it may be possible to get by and be comfortable wearing pants and lightweight jackets but the eventual rise in humidity levels will force your hand in ditching your jackets for tops made of light breathable fabrics like linen and cotton.
Packing essentials for your June trip to South Korea ought to include shorts, summer dresses, cotton or linen shorts and tops, a pair of comfortable walking sandals, dress shoes, sunglasses, sunhats, a jacket, a raincoat or umbrella, and swimwear for your time on the beach.
It's important to keep in mind that while South Korea is very progressive in terms of style and fashion, we recommend you avoid wearing clothes that are overly revealing if you don't want to draw unnecessary attention to yourself.
