Average weather in June 72°F to 80° Lake Forest is a city located in Lake County, IL. The city is along the shore of Lake Michigan, and is a part of the Chicago metropolitan area and the North Shore. Lake Forest was founded with Lake Forest College and was laid out as a town in 1857, a stop for travelers making their way south to Chicago. The Lake Forest City Hall, designed by Charles Sumner Frost, was completed in 1898. It originally housed the fire department, the Lake Forest Library, and city offices. Lake Forest is noted in the Chicago area for its history of polo, once being the westernmost establishment of the sport in the United States. It was home to the "East-West clash of 1933" in which a team of "Westerners" (who would today be considered Midwesterners), challenged the best of the Eastern US polo teams, winning two of three matches. Today, Lake Forest continues the tradition, and polo is played yearly throughout August.
