Greeley is bordered on the south by the towns of Evans and Garden City, and the three together are often collectively (although incorrectly) referred to as "Greeley." The Greeley/Evans area is bounded on the south by the South Platte River, and the Cache la Poudre River flows through north Greeley. The intersection of U.S. Highways 85 and 34 is often cited as the location of Greeley, although the actual point of intersection lies within the city limits of Evans. Greeley contains the western terminus of State Highway 263 and borders State Highway 392 on the north.

Greeley began as the Union Colony, which was founded in 1869 as an experimental utopian community of "high moral standards" by Nathan C. Meeker, a newspaper reporter from New York City. Meeker purchased a site at the confluence of the Cache la Poudre and South Platte Rivers (that included the area of Latham, an Overland Trail station), halfway between Cheyenne and Denver along the tracks of the Denver Pacific Railroad formerly known as the "Island Grove Ranch." The name Union Colony was later changed to Greeley in honor of Horace Greeley, who was Meeker's editor at the New York Tribune, and popularized the phrase "Go West, young man".
Egyptian Islamist Sayyid Qutb studied at the Colorado State College of Education in 1949. In The America I Have Seen (1951), he portrays Greeley as a hotbed of debauchery, rife with "naked legs" and "animal-like" mixing of the sexes.
High temperatures are generally around 90°F (32°C) in the summer and 40°F (4°C) in the winter, although there is significant variation. The hottest days generally occur around the third week of July and the coldest in January. Nighttime lows are near 60°F (16°C) in the summer and around 15°F (-9°C) in the winter. Record high temperatures of 104°F (40°C) have been recorded, as have record low temperatures of -25°F (-32°C). The first freeze typically occurs around October 10 and the last can be as late as May 1. Extratropical cyclones which disrupt the weather for the eastern two-thirds of the US often originate in or near Colorado, which means Greeley does not experience many fully developed storm systems. Warm fronts, sleet, and freezing rain are practically non-existent here. In addition, the city's proximity to the Rocky Mountains and low elevation compared to the surrounding terrain result in less precipitation and fewer thunderstorms and tornadoes than areas immediately adjacent. This is paradoxical, because adjacent areas (mostly farmland) experience between 7 and 9 hail days per year and one of the highest concentrations of tornadic activity anywhere. The area where Colorado, Nebraska and Wyoming meet receives the most hail of any location in the United States .
Some days in the winter and spring can be warm and extremely dry, with Chinook winds often raising temperatures to near 70°F (21°C) in January and February, and sometimes to near 90°F (32°C) in April. Greeley's low year-round humidity means that nighttime low temperatures are practically never above 68°F (20°C), even in the very hottest part of the summer. The diurnal temperature range is usually rather wide, with a 50-degree (Fahrenheit) difference between daytime high and nighttime low not uncommon, especially in the spring and fall months. Rapid fluctuation in temperature is also common – a sunny 80°F (27°C) October afternoon can easily give way to a 28°F (-2°C) blizzard within 12 hours.
In spite of its aridity, Greeley was awarded Tree City USA designation by the National Arbor Day Foundation in 1980, and many of its streets are lined with large trees. This was originally made possible by Greeley's extensive irrigation system; very few trees are actually native to the area. Some of the most common trees and shrubs in Greeley are green ash (fraxinus pennsylvanica), honey locust (gleditsia triacanthos), elms, cottonwoods, sumacs, lindens, pines, blue spruce (picea pungens), apples & crabapples, common lilac (syringa vulgaris), catalpa (catalpa bignonioides), Russian olive (elaeagnus angustifolia), black walnut (juglans nigra L.), and junipers. Other more exotic specimens are also grown, such as golden rain tree (koelreuteria paniculata) and star magnolia (magnolia stellata). Some fruit trees are commonly grown, although their use is usually ornamental; such as plum trees.
There are at least five private schools inside the Greeley city limits: Trinity Lutheran School, St. Mary Catholic School, Dayspring Christian Academy, Shepherd of the Hills, and Mountain View Academy
Greeley is also home to Aims Community College and the University of Northern Colorado.
