The Busan International Film Festival is held annually in late September/early October, and sees multiple big names from across Asia flock to South Korea's second city. Busan is exceptionally active during festival days, which results in higher volumes of tourists and higher accommodation prices.
There is a distinctive change of seasons in Busan, with cold winters and warm summers. Spring is a popular time to visit (particularly because of the iconic cherry blossoms), but summer (May-August) attracts travellers the most. Due to its seaside location, Busan is also a popular summertime destination for internal tourists, who can be seen setting up sunbathing stations across Haundae beach all through the summer.
