Incheon experiences each of its four seasons, distinctly feeling the rise and fall of temperature and humidity. The temperature however, never rises to an extreme, and the climate of the city is essentially mild. Incheon is swept by the seasonal winds as the northwesterly winds strike the city in the winter and the summer in Incheon is affected by gusts of the warm southwesterly winds.<ref>{{cite web|url=http://www.asiarooms.com/travel-guide/south-korea/incheon/incheon--overview/-incheon-weather.html|archive-url=https://web.archive.org/web/20080513231114/http://www.asiarooms.com/travel-guide/south-korea/incheon/incheon--overview/-incheon-weather.html|url-status=usurped|archive-date=13 May 2008|title=AsiaRooms – LateRooms – Last Minute Hotel Deals & Cheap Hotels|work=asiarooms.com}}</ref>
