Albuquerque is located in north-central New Mexico. To its east are the
Sandia–Manzano Mountains. The
Rio Grande flows north to south through its center, while the
West Mesa and
Petroglyph National Monument make up the western part of the city. Albuquerque has one of the highest elevations of any major city in the U.S., ranging from
above sea level near the Rio Grande to over in the foothill areas of
Sandia Heights and Glenwood Hills. The civic apex is found in an undeveloped area within the Albuquerque Open Space; there, the terrain rises to an elevation of approximately , and the metropolitan area's highest point is
Sandia Crest at an altitude of . According to the
United States Census Bureau, Albuquerque has a total area of , of which is land and , or 0.96%, is water. Albuquerque lies within the fertile
Rio Grande Valley with its
Bosque forest, in the center of the
Albuquerque Basin, flanked on the eastern side by the
Sandia Mountains and to the west by the
West Mesa. Located in central New Mexico, the city also has noticeable influences from the adjacent
Colorado Plateau semi-desert, New Mexico Mountains forested with juniper and pine, and Southwest plateaus and plains steppe ecoregions, depending on where one is located.
Landforms and drainage Albuquerque has one of the highest and most varied elevations of any major city in the United States, though the effects of this are greatly tempered by its southwesterly continental position. The elevation of the city ranges from 4,949 feet (1,508 m)
above sea level near the Rio Grande (in the Valley) to 6,165 feet (1,879 m) in the foothill areas of
Sandia Heights. At the
Albuquerque International Sunport, the elevation is 5,355 feet (1,632 m) above sea level. The Rio Grande is classified, like the
Nile, as an "exotic" river. The New Mexico portion of the Rio Grande lies within the
Rio Grande Rift Valley, bordered by a system of
faults, including those that lifted up the adjacent
Sandia and
Manzano Mountains, while lowering the area where the life-sustaining Rio Grande now flows.
Geology and ecology Albuquerque lies in the
Albuquerque Basin, a portion of the
Rio Grande rift. The
Sandia Mountains are the predominant geographic feature visible in Albuquerque.
Sandía is Spanish for "
watermelon", and is popularly believed to be a reference to the brilliant pink and green coloration of the mountains at sunset. The pink is due to large exposures of
granodiorite cliffs, and the green is due to large swaths of
conifer forests. However, Robert Julyan notes in
The Place Names of New Mexico, "the most likely explanation is the one believed by the
Sandia Pueblo Indians: the Spaniards, when they encountered the Pueblo in 1540, called it Sandia, because they thought the squash growing there were watermelons, and the name Sandia soon was transferred to the mountains east of the pueblo." He also notes that the Sandia Pueblo Indians call the mountain
Bien Mur, "Big Mountain." The network of channels was built by the Army Corps of Engineers during the 1960s and early 1970s.
Cooper's hawks are common in city parks. Iconic vegetation in town varies by the terrain and soil type; in much of Albuquerque that includes the
Rio Grande cottonwood, Gooding's and coyote willow,
Arizona walnut, and
alkali sacaton in the bosque; on the edges of the Rio Grande floodplain some remaining
New Mexico olive,
screwbean mesquite, and
lead plant occur.
tree cholla, various
prickly pear and
yucca,
chamisa, and
oneseed juniper occur in upland areas as part of the desert grassland plant community, within a cover of arid grasses including
black grama and
purple three awn, mostly east of I-25 and above the west mesa's volcanic escarpment. West of the Rio Grande but below the escarpment, the mesa sand scrub plant community includes
sand sagebrush,
broom dalea,
fourwing saltbush, and sandy soil-adapted grasses including various
dropseed and
indian ricegrass; some stands of
mariola,
beebrush,
threeleaf sumac,
littleleaf sumac, and
blackspine prickly pear grow along or near the volcanic escarpment. The foothill open space at the eastern border of the city limits also features
Sonoran scrub oak, with
gray oak and some
Colorado piñon trees in more mesic locations.
Desert willow is a native tree along some arroyos, and they are now commonly planted throughout the city;
western honey mesquite and
netleaf hackberry occur in small numbers beyond developed areas, as do remaining stands of
creosote bush on the southern edge of the city.
Tumbleweeds are a common weed in disturbed areas, and are used by Albuquerque's flood control authority, to make an annual holiday snowman adjacent to their headquarters building, near the "Big-I" interchange near the city's center.

Quadrants Albuquerque is geographically divided into four unequal
quadrants that are officially part of mailing addresses, placed immediately after the street name. They are Northeast (NE), Northwest (NW), Southeast (SE), and Southwest (SW). Albuquerque's official quadrant system uses Central Ave for the north–south division and the railroad tracks for the east–west division. I-25 and I-40 are also sometimes used informally to divide the city into quadrants.
Northeast This quadrant has been experiencing a housing expansion since the late 1950s. It abuts the base of the Sandia Mountains and contains portions of the foothills neighborhoods, which are significantly higher in elevation than the rest of the city. Running from Central Ave and the
Railrunner tracks to the
Sandia Peak Aerial Tram, this is the largest quadrant both geographically and by population. Martineztown, the
Maxwell Museum of Anthropology,
University of New Mexico, the Uptown area, which includes three shopping malls (
Coronado Center, ABQ Uptown, and
Winrock Town Center), Hoffmantown, Journal Center, and
Cliff's Amusement Park are all in this quadrant. Some of the most affluent neighborhoods in the city are here, including:
High Desert, Tanoan, Sandia Heights, and North Albuquerque Acres. Parts of Sandia Heights and North Albuquerque Acres are outside the city limits proper. A few houses in the farthest reach of this quadrant lie in the
Cibola National Forest, just over the line into
Sandoval County.
Northwest in Downtown This quadrant contains historic
Old Town Albuquerque, which dates to the 18th century, as well as the
Indian Pueblo Cultural Center. The area has a mixture of commercial districts and low to high-income neighborhoods. Northwest Albuquerque includes the largest section of
Downtown,
Rio Grande Nature Center State Park and the
Bosque ("woodlands"), Petroglyph National Monument,
Double Eagle II Airport, the Paradise Hills neighborhood, Taylor Ranch, and
Cottonwood Mall. This quadrant also contains the
North Valley settlement, outside the city limits, which has some expensive homes and small ranches along the
Rio Grande. The city of Albuquerque engulfs the village of
Los Ranchos de Albuquerque. A small portion of the rapidly developing area on the west side of the river south of the Petroglyphs, known as the "
West Mesa" or "Westside", consisting primarily of traditional residential subdivisions, also extends into this quadrant. The city proper is bordered on the north by the North Valley, the village of
Corrales, and the city of
Rio Rancho.
Southeast in Nob Hill
Kirtland Air Force Base,
Sandia National Laboratories, Sandia Science & Technology Park, MaxQ@Kirtland,
Albuquerque International Sunport,
American Society of Radiologic Technologists,
Central New Mexico Community College,
UNM South Campus, Presbyterian Hospital, VA Medical Center, Duke City BMX,
University Stadium,
Isotopes Park,
The Pit,
Mesa del Sol,
Isleta Amphitheater,
Netflix Studios, Pacific Fusion, Isleta Resort & Casino,
National Museum of Nuclear Science & History, New Mexico Veterans Memorial, and Market are all located in the Southeast quadrant of Albuquerque. The Four Hills neighborhood is located in the foothills of Southeast Albuquerque. The Volterra subdivision lies west of Four Hills. Popular urban neighborhoods that can be found in Southeast Albuquerque include
Nob Hill, Ridgecrest, Parkland Hills, Hyder Park, and University Heights.
Southwest Traditionally consisting of agricultural and rural areas and suburban neighborhoods, the Southwest quadrant comprises the south-end of Downtown Albuquerque, the
Barelas neighborhood, the rapidly growing west side, and the community of
South Valley, New Mexico, often called "The South Valley". The quadrant extends all the way to the Isleta Indian Reservation. Newer suburban subdivisions on the
West Mesa near the southwestern city limits join homes of older construction, some dating as far back as the 1940s. This quadrant includes the old communities of Atrisco, Los Padillas, Huning Castle, Kinney, Westgate, Westside, Alamosa, Mountainview, and Pajarito. The Bosque ("woodlands"), the
National Hispanic Cultural Center, the
Rio Grande Zoo, and
Tingley Beach are also here. A new adopted development plan, the Santolina Master Plan, will extend development on the west side past 118th Street SW to the edge of the
Rio Puerco Valley and house 100,000 by 2050.
Climate Albuquerque's climate is classified as a
cold semi-arid climate (
BSk) according to the
Köppen climate classification system, while the Biota of North America Program and the U.S. Geological Survey describe it as warm temperate semi-desert. Albuquerque is located near the crossroads of several ecoregions. According to the
U.S. Environmental Protection Agency, the city is located in the southeastern edge of the
Arizona/New Mexico Plateau, with the
Arizona/New Mexico Mountains ecoregion defining the adjacent Sandia-Manzano mountains, including the foothills in the eastern edges of the city limits, above Juan Tabo Boulevard. Though the city lies at the northern edge of the
Chihuahuan Desert transitioning into the
Colorado Plateau, much of Albuquerque's area west of the
Sandia Mountains shares similar temperatures, aridity, yearly precipitation patterns, and natural vegetation with the Chihuahuan Desert, namely the desert grassland and sand scrub plant communities. The eastern portion of the greater Albuquerque area is known as the East Mountain area, and it is within the
Southwestern Tablelands, sometimes considered a southern extension of the central high plains or northeast New Mexico highlands. To the north is the
Southern Rockies ecoregion in the Jemez Mountains. The average annual precipitation is less than half of evaporation supporting an
arid climate (
BWk), according to a more recent application of the
Köppen climate classification system using over a century of climatology, with no month's daily mean temperature averaging below freezing. The climate is mild compared to many parts of the continent farther north or east, protected by mountains and surrounding highlands. However, due to the city's high elevation, low temperatures in winter often dip below freezing. Varied terrain and elevations within the city and outlying areas cause daily temperature differentials to vary. The daily mean temperatures in December and January, the coldest months, are above freezing at at the elevation Albuquerque International Airport station, representative of much of the city, and at the elevation Albuquerque Foothills NE station. Albuquerque's climate is usually sunny and dry, with an average of 3,415 sunshine hours per year. Brilliant sunshine defines the region, averaging 278 days a year; periods of variably mid and high-level cloudiness temper the sun, mostly during the cooler months. Extended cloudiness lasting longer than two or three days is rare. Winter typically consists of cool days and cold nights, except following passage of the strongest cold fronts and arctic airmasses when daytime temperatures remain colder than average; overnight temperatures tend to fall below freezing between about 12 am and 9 am in the city, except during colder airmasses, plus colder spots of the valley and most of the East Mountain areas. December, the coolest month, averages ; the median or normal coolest temperature of the year is , while the average or mean is about . It is typical for daily low temperatures in much of December to mid-February to be below freezing, with a long-term average of 93 days per year falling to or below freezing, and two days failing to rise above freezing. Winter is the second driest season in much of Albuquerque, and while rain makes up more of the season's precipitation than snow, December is the snowiest month on average By March, stronger winds occur on many afternoons, as temperatures warm with the change to spring weather patterns and storm systems pass to the north. Portions of the valley and West Mesa locations experience more high temperatures above and as part of normal or extreme weather each summer. Autumn is generally cool in the mornings and nights but sees less rain than summer, though the weather can be more unsettled closer to winter, as colder airmasses and weather patterns build in from the north and northwest with more frequency. Some years, a storm in November may cause a snow accumulation of one to two inches. Precipitation averages per year. On average, January is the driest month, while July and August are the wettest months, as a result of shower and thunderstorm activity produced by the monsoon prevalent over the Southwestern United States. Most rain occurs during the late summer monsoon season, typically starting in early June and ending in mid-September. Albuquerque averages of snow per winter, and experiences several accumulating snow events each season. Locations in the Northeast Heights and foothills tend to receive more snowfall due to each region's higher elevation and proximity to the mountains. East Mountain communities average more snow and at times not usually experienced in the city. The metro area was one of several in the region experiencing a severe winter storm on December 28–30, 2006, with locations in the Albuquerque area receiving between of snow. More recently, a major winter storm in late February 2015 dropped up to a foot (30 cm) of snow on most of the city. Such large snowfalls are rare occurrences during the period of record, and they greatly impact traffic movement and the workforce due to their rarity. The mountains and highlands east of the city create a
rain shadow effect from moist Gulf airmasses moving towards the area, due to the drying of air descending the west side of the mountains into much of Albuquerque; the Sandia Mountains tend to lift any available moisture, enhancing precipitation to about annually. Traveling west, north, and east of Albuquerque, one quickly rises in elevation, leaving the sheltering effect of the valley to enter a noticeably cooler and slightly wetter environment. One such area is considered part of Albuquerque Metropolitan Area, commonly called the East Mountain area, is covered in woodlands of juniper and piñon trees, a common trait of southwestern uplands and the southern Rocky Mountains. Albuquerque's growing season averages 208 days, which is the total consecutive days of low temperature above between the last spring freeze and first fall freeze, based on 1991 to 2020 climatology at the Sunport. The growing season can vary depending on local terrain or the year, and is shorter in colder locales of the valley, foothills, and especially the East Mountains; Sandia Park averages a growing season of 152 days.
Hydrology Albuquerque's drinking water comes from a combination of Rio Grande water (river water diverted from the
Colorado River basin through the
San Juan–Chama Project) and a delicate
aquifer that has been described as an "underground
Lake Superior". The Albuquerque Bernalillo County Water Utility Authority (ABCWUA) has developed a water resources management strategy that pursues
conservation and the direct extraction of water from the Rio Grande for the development of a stable underground aquifer in the future. The aquifer of the
Rio Puerco is too
saline to be cost-effectively used for drinking. Much of the rainwater Albuquerque receives does not recharge its aquifer. It is diverted through a network of paved channels and arroyos, and empties into the
Rio Grande. Of the per year of the water in the upper
Colorado River basin entitled to municipalities in New Mexico by the
Upper Colorado River Basin Compact, Albuquerque owns 48,200. The water is delivered to the Rio Grande by the
San Juan–Chama Project. The project's construction was initiated by legislation signed by President
John F. Kennedy in 1962, and was completed in 1971. This diversion project transports water under the
continental divide from
Navajo Lake to Lake Heron on the Rio Chama, a tributary of the Rio Grande. In the past much of this water was resold to downstream owners in Texas. These arrangements ended in 2008 with the completion of the ABCWUA's Drinking Water Supply Project. The ABCWUA's Drinking Water Supply Project uses a system of adjustable-height dams to skim water from the Rio Grande into
sluices that lead to
water treatment facilities for direct
conversion to potable water. Some water is allowed to flow through central Albuquerque, mostly to protect the endangered
Rio Grande silvery minnow.
Treated effluent water is recycled into the Rio Grande south of the city. The ABCWUA expects river water to comprise up to seventy percent of its water budget in 2060.
Groundwater will constitute the remainder. One of the policies of the ABCWUA's strategy is the acquisition of additional river water. ==Demographics==
