Oswego (/ɒsˈwiːɡoʊ/ pronounced: "oss-WEE-go" as in the word we) is a village in Kendall and Will counties, Illinois, United States. Per the 2020 census, the population was 34,485.[3] Oswego is the largest municipality in Kendall County. Part of the Chicago metropolitan area, it is an exurb of Chicago.[4][5]

In 1833, William Smith Wilson, his wife Rebecca, and his brother-in-law Daniel Pearce moved to the area now known as Oswego.[6] The land belonged to the local Potawatomi, Ottawa, and Chippewa tribes, but the United States government removed the Native Americans when the government started surveying the land along the Fox River in Kendall County. In 1842, the federal government placed the land for sale at an established price of $1.25 an acre.[7]
After the sale of the land, Lewis Brinsmaid Judson and Levi F. Arnold from New York laid out the village and named it "Hudson". However, when a post office was established, its location was given as "Lodi". Confusion over the official name of the area led to a decision in January 1837, when the citizens gathered and voted "Oswego" as the permanent name of the village by a single vote.[8] The village was named after Oswego, New York, "Oswego" being an Iroquois word meaning "mouth of the stream".[9] The ford across the Fox River in the town allowed Oswego to grow economically and as a town, eventually incorporated in 1852 with its village boundaries at the time being Harrison Street to the northwest, Jefferson Street to the northeast, Monroe Street to the southeast, and Benton Street to the southwest.[10] At the advent of the automobile, Oswego continued to see growth as it became a hub for three different state highways (Illinois Route 25, Illinois Route 71, and Illinois Route 31).[6]
Major community developments began when Caterpillar Inc. and Western Electric built industrial plants near Oswego in the mid-1950s.[11] This initially allowed nearby Boulder Hill to develop.[12] The next major development arrived in the mid-1980s during the suburban homebuilding boom, which allowed houses and buildings to populate the village. The rapid growth of the village allowed its limits to expand west of the Fox River into today's boundaries.[6]
Oswego is known to some Chicago-area residents for the town dragstrip on State Route 34, which was open from 1955 until 1979, where muscle cars were raced by drivers from all over the Midwest.[13][14] The drag days are still celebrated even though the strip has been closed for decades.[15] Although evidence of the drag strip, including parts of the track, still remain, the site is off limits to the public.
Oswego is located in northeastern Kendall County on the Fox River with a small portion in Will County. It is bordered to the north by Boulder Hill and Montgomery, to the east by Aurora, and to the west by Yorkville, the Kendall county seat.
According to the 2010 census, the village of Oswego has a total area of 15.63 square miles (40.5 km2), of which 15.53 square miles (40.2 km2) (or 99.36%) is land and 0.11 square miles (0.28 km2) (or 0.70%) is water.[16]
Downtown Oswego is home to historic buildings and homes, as well as shops and restaurants. The Village of Oswego launched a project to enhance and restore the historic downtown district. This project included significant infrastructure and streetscape improvements, such as the installation of brick pavers, sidewalks, landscaping, and decorative streetlights and benches. Hudson Crossing Park, located along the Fox River, opened in October 2004 where many children and families enjoy the scenery. The Waubonsee Creek Promenade, which stretches from Main Street to the new park, is the final phase of the downtown enhancements.[17] In 2008, the village celebrated its 175th anniversary.
The Oswego area is home to over 1,100 acres (450 ha) of open land, trails, and parks maintained by the Oswegoland Park District. Established in 1950, this governmental agency is guided to "create opportunities for a healthy community". Overseeing 63 parks, 16 miles (26 km) of walking trails, two aquatic parks, and the Little White School Museum, the park district provides offerings for the community of 20,000 households as well as visitors from farther away.
The Oswego area holds several races for fitness enthusiasts. Several area festivals are coordinated by the park district, such as the annual PrairieFest.[18]

In the Dfa zones the spring and summer months can have severe weather, including tornadoes, when the polar front is in the southern margin of the zone. The region has four distinct seasons. Winters tend to be cold and have ample snow. Springs tend to be humid, and can have precipitation and storms. Summers tend to be hot and have the highest precipitation overall as well as storms. Fall tends to cool down. Like many Chicago suburbs Oswego is in USDA Plant Hardiness Zone 5b. [26]

Many parts of Oswego is next to the Fox Valley River. Due to this many of the areas by the river have a possibility of flooding. Oswego has multiple "Zone AE" locations alongside the river.[28] Zone AE is a Special Flood Hazard Area.[29] Zone AE is a high-risk area. Mandatory flood insurance is commonplace in these areas and may be required. In addition to by the river, some fields in Oswego have risk of flooding. The fields typically have "Zone A" classifications, which is less than Zone AE but still a factor that should be considered.
Oswego and the surrounding area is part of the extended tornado alley (though not typically classified as being part of the 'main tornado alley).[30] Being so, tornadoes are an event that Oswego has risk of happening. Tornadoes can occur at any time of the year but they are most frequent between April and June, with May being the peak. They tend to happen in the afternoon/evening hours with 50% occurring between 3 p.m. and 7 p.m. for Illinois as a whole. Illinois (as a whole) averaged 54 tornadoes per year based on the 1991-2020 data.[31]

August 28, 1990 Plainfield F-5 Tornado
This tragic tornado touched down in Oswego on August 28th 1990 at 3:15 PM. The tornado had a maximum rating of EF-3 for Oswego specifically, as it got up to F-5 later in Plainfield. This tornado is notable for many reasons. One of them is the lack of warning, there was no warning issued for this area, which was one of the causes in the unfortunate number of injuries and fatalities this tornado had. As a result of this tornado (and the lack of a warning) it helped cause the NWS to begin leaning on the side of caution and issuing more tornado warnings than actual tornadoes. This tornado tragically took the lives of 29 people and injured 350. The majority of fatalities and deaths took place outside of Oswego, particularly in Plainfield where it reached its F-5 rating. An estimated total of $160 million dollars in damages was estimated as a whole and a total of 470 homes were destroyed and 1000 damaged overall. The tornado is also notable for being the first and only F/EF-5 tornado in the month of August. In addition, its path head southeast, which is unusual for tornadoes which typically head east/north-east. The damage path of the tornado can still be seen today.[33][34]
The closest weather station to Oswego is the Romeoville station (with the station code KLOT for Lewis University Airport). It is located next to Lewis University in Romeoville. It is about 10 miles away from Oswego and is home of the local weather radar.
