Since Typhoon Maemi took a path closer to the form of a parabolic, a typical pattern of typhoons from outbreak to extinction, it was relatively possible to predict its course and the possibility of landing on the Korean Peninsula was expected fairly early. The Korea Meteorological Administration officially announced the typhoon's possible landing off the southern coast of the Korean Peninsula at 5 p.m. on Sept. 10, making the news widely known through major media organizations. When Typhoon Maemi struck South Korea, it caused heavy rainfall that peaked at . Rainfall reached in Namhae County, and on Jeju Island. The rain was less widespread and caused less flooding than Typhoon Rusa, which struck the country a year prior, but damage from Maemi was heavier due to strong winds. On Jeju Island, Maemi produced a wind gust of 216 km/h (134 mph) and a minimum pressure of , both setting records for the country. The winds broke the record of 210 km/h (130 mph) set by Typhoon Prapiroon in 2000, and the pressure was 1.5 mbar lower than that during Typhoon Sarah in 1959, which was one of the strongest storms to strike South Korea after Maemi. On the South Korean mainland, the Pusan International Airport reported wind gusts of 143 km/h (89 mph). Winds in Busan reached 154 km/h (96 mph), the second-highest wind speed for the city after Typhoon Thelma in 1987. Due to high winds, five nuclear power plants were shut down automatically, but were ultimately unaffected.
