This season offers mild temperatures, blooming flowers, and plenty of sunshine. Here’s what you can expect in some of the most popular destinations:

• Seoul: In May, temperatures in Korea’s iconic capital typically range from 8°C to 17°C (46°F to 63°F). The cooler spring days in Seoul are well-suited for uncovering serene shrines in Korea, grand palaces, traditional neighborhoods, and much more.
• Busan: Coastal South Korea is at its best in May, boasting temperatures between 14°C and 23°C (57°F and 73°F). With sunny skies and refreshing sea breezes, it’s a fantastic time to unwind on Busan’s picturesque beaches, experience lively outdoor markets, or stroll along the coastline for beautiful ocean views.

Crowds

May is widely regarded as the best time to visit South Korea because of its temperate weather, fewer cherry blossom crowds, and abundant outdoor activities before the hot, humid summer begins in South Korea in June. Major attractions are busier than usual, but crowds remain manageable, especially due to the balanced South Korea temperature in May. Prominent cities like Seoul and Busan are full of tourists visiting palaces, markets, and scenic treasures, while Jeju Island sees a steady flow of tourists enjoying its gorgeous trails. Gyeongju draws travelers to historic temples and tombs, though these spots rarely feel overcrowded thanks to their spacious layouts. To ensure a more relaxed journey, visit famous sites early in the day or on weekdays, and book tours and lodging in advance, as they can fill up quickly. 

Price Fluctuations

May in South Korea brings mild weather and vibrant spring scenery, but costs can vary depending on the timing of your trip:

• Early May: This is the busiest time of the month, particularly around weekends and nearby holidays like Golden Week. Also, airfare and hotel rates can be higher, so it’s best to reserve your preferred travel and overnight arrangements ahead of time.
• Late May: The second half of the month becomes generally quieter. Many early-May travelers have returned home, and spring festivals are mostly over, so popular landmarks are easier to explore without crowds. Flights and accommodations are often more affordable, making it an incredible time to visit if you favor a more leisurely pace.
