Minneapolis - Geography and Climate

Geography and Climate

The history and economic growth of Minneapolis are tied to water, the city's defining physical characteristic, which was brought to the region during the last ice age ten thousand years ago. Fed by a receding glacier and Lake Agassiz, torrents of water from a glacial river cut the Mississippi riverbed and created the river's only waterfall, St. Anthony Falls, important to the early settlers of Minneapolis. Lying on an artesian aquifer and flat terrain, Minneapolis has a total area of 58.4 square miles (151.3 km2) and of this 6% is water. Water is managed by watershed districts that correspond to the Mississippi and the city's three creeks. Twelve lakes, three large ponds, and five unnamed wetlands are within Minneapolis.

The city center is located at 45° N latitude. The city's lowest elevation of 686 feet (209 m) is near where Minnehaha Creek meets the Mississippi River. The site of the Prospect Park Water Tower is often cited as the city's highest point and a placard in Deming Heights Park denotes the highest elevation, but a spot at 974 feet (297 m) in or near Waite Park in Northeast Minneapolis is corroborated by Google Earth as the highest ground.

Minneapolis has a continental climate typical of the Upper Midwest. Winters are cold and snowy, while summers are hot and humid. On the Köppen climate classification, Minneapolis falls in the hot summer humid continental climate zone (Dfa) and has a USDA plant hardiness of zone 5a/4b. As is typical in a continental climate, the difference between average temperatures in the coldest winter month and the warmest summer month is great: 60.1 °F (33.4 °C).

The city experiences a full range of precipitation and related weather events, including snow, sleet, ice, rain, thunderstorms, tornadoes, heatwaves, and fog. The warmest temperature ever recorded in Minneapolis was 108 °F (42 °C) in July 1936, and the coldest temperature ever recorded was −41 °F (−41 °C), in January 1888. The snowiest winter of record was 1983–84, when 98.4 inches (250 cm) of snow fell.

The average annual temperature in the Minneapolis–Saint Paul metropolitan area is 45.4 °F (7.4 °C).

Famous quotes containing the words geography and, geography and/or climate:

    At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.
    Derek Wall (b. 1965)

    Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.
    Ralph Waldo Emerson (1803–1882)

    Is not their climate foggy, raw, and dull,
    On whom, as in despite, the sun looks pale,
    Killing their fruit with frowns?
    William Shakespeare (1564–1616)
