ISeoul is the capital and largest metropolis of the Republic of Korea, located in the western part of the central region of the Korea Peninsula. The word "seoul" means "capital city" in Korean. Seoul has been the center of the country throughout its long history, and now this city is home to over 10 million citizens. Seoul is surrounded by vast mountains and crossed by the Han River. The Han River flows horizontally across Seoul, dividing the city in two sections lying north and south of the river. Today, Seoul is a leading and rising global city, resulting from an economic boom and growth. The fast-paced and high tech city embraces both tradition and modernity, making it a very unique city.
Seoul has all four clearly distinguished seasons. Spring begins around early March; cherry blossom and flower festivals around the entire country signal the official coming of spring. The summer months can get quite hot and humid, but be ready for random spurts of coldness when stepping into a subway car, bus, or any other air-conditioned facilities in Seoul. For about a month starting from mid-July is the rainy season. Autumn start around September and boasts beautiful scenery as leaves begin to turn into fall colors. The winters in Seoul can get quite harsh. The temperature can drop as low as 15 degrees below zero (Celsius) during the coldest days.
