January is the least expensive month for flying to South Korea. It’s a great time for quieter travel and enjoying winter sports. If you’re not a fan of freezing temperatures, the next affordable months to fly are October, November,  and March. During these times, fewer tourists visit due to the cold weather, making accommodations and flights more budget-friendly.

However, it’s best to avoid the summer months of July and August in Seoul. This period is very busy with tourists, and the weather is extremely hot and humid. Heavy rain is also common due to the East Asia monsoon. With large crowds, long lines, and higher accommodation prices, it’s not the best time for a pleasant visit.
