Seoul, the capital of South Korea, is home to about 10.3 million people, making it one of Asia's largest capitals. Travelers can plan around three daily cost tiers: budget trips run about $65 a day, mid-range around $155, and luxury near $335; over a full week those figures come to $455, $1,085, and $2,345. The city has a distinct four-season climate, with cold, dry winters and hot, humid summers. June and September stand out as the best months to visit, offering warm temperatures — highs of about 27.7C in June and 26.6C in September — combined with strong sunshine hours and less extreme heat than the peak of summer. Peak tourist months run from June through September, while January, November, and December are the quietest and least expensive times to visit. Safety guidance for South Korea is generally reassuring at the country level, though travelers should stay aware of regional political tensions and take normal urban precautions. Seoul rewards visitors who plan around its seasons, balancing weather, crowds, and cost through the year.
