Jeju has very different weather to mainland Korea and is famous for its almost constant strong winds caused to the sieving atmospheric pressures above the island. These strong winds pass over the surrounding seas capturing moisture which, when forced to rise by Jeju’s mountains, causes rain to fall. Jeju has the highest amount of wet days in Korea but equally the most pleasant winters; the winters are mild with only a slight snow dusting on the highest peaks. Spring is the ideal time of year to visit Jeju before the high humidity of summer. The Korean’s regard July to September as the beach season but high temperatures and humidity make it almost impossible to do anything else. The typhoon season occurs in late summer but Jeju rarely experiences truly destructive typhoons.
