Climate 

Sioux Falls has a humid continental climate (Köppen Dfa), which is typified by hot, humid summers and cold, dry winters. This is because the city is located in the interior and is relatively high latitude. USDA Plant Hardiness Zone 4b is where it is. There are 25 days per year with minimum temperatures at or below 0 °F (18 °C), and there are 15 days each year with maxima at or above 90 °F (32 °C). The monthly daily average temperature ranges from 17.9 °F (7.8 °C) in January to 74.4 °F (23.6 °C) in July. Throughout the winter, snowfall averages low to moderate levels, totaling 45.3 inches (115 cm). The majority of precipitation, about 27.85 inches (707 mm), falls during the warmer months. As a result of the convection building up due to the unstable weather patterns, thunderstorms occur frequently throughout the summer. From 42 °F (41 °C) on February 9, 1899, to 110 °F (43 °C) as recently as June 21, 1988, there have been extremes. 

  

Economy 

Sioux Falls is home to a variety of financial enterprises, in part because there is no state corporate income tax. Wells Fargo and Citigroup are among them the two biggest employers. 

Although it is not as economically dominating as it once was, Sioux Falls' manufacturing and food processing sector still plays a significant role in the local economy. The third-largest employment in the city is the meatpacking facility owned by Smithfield Foods and John Morrell. 

  

Government 

A mayor-council system (strong mayor) governs the city of Sioux Falls. Every four years, there are elections for mayors. Every four years, elections are held for city council seats as well. Although the elections are spaced out over even-numbered years, not every councilmember is chosen in the same year. The city council is made up of three more seats that represent the entire city and five additional members who are elected to represent particular districts within the city (that is, at-large). The role of councilmember is intended to be part-time. Sioux Falls is governed by a home rule charter, as allowed by South Dakota law. 

George W. Bush received 56% of the vote in Minnehaha County and 65% in Lincoln County in the 2004 presidential election, respectively. Minnehaha County went for Barack Obama by 0.7% in 2008, while Lincoln County went for John McCain by 15%. Since 2012, both counties have consistently supported the GOP candidate in presidential elections. 

  

Infrastructure 

Transportation 

Roads 

The majority of people in Sioux Falls commute and travel by car. While Interstate 29 divides the western part of the city from the north and south, Interstate 90 runs through the northern boundary of the city from east to west. Interstate 229 connects to I-90 to the northeast and I-29 to the southwest as it makes a partial loop around Sioux Falls. In the center (historical) part of the city, a grid design scheme is the norm; minor streets in newer residential districts have mostly abandoned this layout. 

Several sizable construction projects have been or will be undertaken as a result of the existing and anticipated expansion in the region. I-29 has recently gained new interchanges. I-90 at Marion Road now has a full interchange. Recent upgrades have been made to I-29 between I-90 and 57th Street. Additional lanes as well as support lanes are part of this development. South Dakota Highway 100, a limited-access road, will be built around the southern and eastern boundaries of Sioux Falls over the course of the following ten years by the city of Sioux Falls and the South Dakota Department of Transportation. Starting from the northern Tea exit (Exit 73 on I-29, 101st Street), this road will travel east on 101st Street, bend northeast east of Western Avenue, and then turn north close to Sycamore Avenue. It will conclude with the exit for Timberline Avenue (Exit 402 on I-90). The principal thoroughfares in Sioux Falls are W 41st, Minnesota, Main, W 26th (which changes its name to Louise as it curves to the south), 12th, 49th, 57th, and Western. 

  

Public Transportation 

The city's 16 bus lines are run by Sioux Area Metro, the regional public transportation system, with the majority of the routes running from Monday through Saturday. On Louise Avenue between 49th and 57th Streets in Sioux Falls, the city recently erected a new transfer station. The Sioux Area Metro Paratransit provides door-to-door service to community people who would not otherwise be able to travel. 

Throughout the city, a number of taxi firms are also in operation. 

Long-distance bus lines are operated by Jefferson Lines to Sioux Falls. The cities of Grand Forks, Kansas City, Minneapolis, and Omaha are among the non-transfer destinations. A Chicago-bound Milwaukee Railway train branch called the Arrow made a stop in Sioux Falls up until 1965. 

South Dakota is not a stop on the Amtrak passenger train network.
