The city is located on the south shore of the
Keweenaw Waterway, on rolling wooded hills, less than a mile across Portage Lake from
Hancock. The city is bounded on the east by
Portage Township and Pilgrim, on the west by
Dakota Heights and
Adams Township, and on the south by
Hurontown and Isle Royale Location, unincorporated communities that are part of Portage Township. Houghton is named after

Portage Lake is the Raymond Kestner Waterfront Recreation Area, the principal feature of which is a large "
Chutes and Ladders"
playground; it also includes Houghton Beach. Along the waterfront, in the area that used to be occupied by the railroad tracks, runs the flat, paved
Waterfront Trail for cyclists and pedestrians; at one end of this is the Houghton RV Park, at the other end the Nara Nature Park and midway along this corridor is
Mattila Square. Veterans Park is just across the
Portage Lake Lift Bridge from Hancock, and contains the memorial to the Houghton Company, which fought in the
Civil War. Houghton is the headquarters for
Isle Royale National Park. The
Portage Lift Bridge spans
Portage Lake, which is part of the river and canal system that crosses the entire peninsula, connecting
Hancock and Houghton. The bridge, which provides of vertical clearance for ships when open, is the world's heaviest and widest double-decked vertical lift bridge. Since rail traffic was discontinued in the Keweenaw, the lower deck is used to accommodate
snowmobile traffic in the winter. The bridge provides the only link between the north and south sections of the Keweenaw peninsula.

humid continental climate (
Köppen Dfb) but the (typically) long and snowy (due to lake-effect snow, with an average of ) winters make the city feel as though it is in a climate much farther north. It holds the distinction of having the third-most (behind
Duluth and
International Falls in
Minnesota) maxima below of any incorporated city in the contiguous US, with the top temperature failing to rise above freezing an average of 100.9 days per year. While Houghton's winters may be the subject of humor, residents take the subject of snow and winter very seriously. Houghton is a
Winter City—a community that accommodates winter, celebrates it, and whose residents generally enjoy the season by participating in a variety of outdoor activities. Among those activities are cross country skiing, snow-shoeing, ice fishing, snowmobiling, ice skating and outdoor ice hockey, among other activities. Houghton celebrates winter through the “Winter Carnival” organized by Michigan Tech every year in February.

The city's record high temperature of was recorded July 7, 1988; this is the only day in the city's history with a temperature over .
