Wyoming's climate is generally [[Semi-arid climate|semi-arid]] and [[continental climate|continental]] ([[Köppen climate classification]] ''[[Cold steppe|''BSk'']]'') and is drier and windier in comparison to most of the United States with greater temperature extremes.<ref>{{cite web|url=http://www.wrds.uwyo.edu/sco/wyoclimate.html|title=The Climate of Wyoming|publisher=Wyoming State Climate Office and Water Resources Data System|accessdate=April 14, 2023}}</ref><ref>{{cite web|url=https://www.nps.gov/fola/planyourvisit/weather.htm?fullweb=1|title=Weather|publisher=[[U.S. National Park Service]]|accessdate=April 14, 2023}}</ref> Much of this is due to the topography of the state. Summers in Wyoming are warm with July high temperatures averaging between {{convert|80|and|90|°F|°C|abbr=on}} in most of the state. With increasing elevation, however, this average drops rapidly with locations above {{convert|9000|ft|m}} averaging around {{convert|70|°F|°C|abbr=on}}. Summer nights throughout the state are characterized by a rapid cooldown with even the hottest locations averaging in the {{convert|50|–|60|F|C}} range at night. In most of the state, most of the precipitation tends to fall in the late spring and early summer. Winters are cold but are variable with periods of sometimes extreme cold interspersed between generally mild periods, with [[Chinook winds]] providing unusually warm temperatures in some locations.

Wyoming is a dry state with much of the land receiving less than {{convert|10|in|mm}} of rainfall per year. Precipitation depends on elevation with lower areas in the [[Bighorn Basin|Big Horn Basin]] averaging {{convert|5|-|8|in|mm}}, making the area nearly a true [[desert]]. The lower areas in the North and on the eastern plains typically average around {{convert|10|-|12|in|mm}}, making the climate there [[semi-arid]]. Some mountain areas do receive a good amount of precipitation, {{convert|20|in|mm}} or more, much of it as snow, sometimes {{convert|200|in|cm}} or more annually. The state's highest recorded temperature is {{convert|114|F|C}} at [[Basin, Wyoming|Basin]] on July 12, 1900, and the lowest recorded temperature is {{convert|-66|F|C}} at [[Riverside, Wyoming|Riverside]] on February 9, 1933.

The number of [[thunderstorm]] days varies across the state with the southeastern plains of the state having the most days of thunderstorm activity. Thunderstorm activity in the state is highest during the late spring and early summer. The southeastern corner of the state is the most vulnerable part of the state to [[tornado]] activity. Moving away from that point and westwards, the incidence of tornadoes drops dramatically with the west part of the state showing little vulnerability. Tornadoes, where they occur, tend to be small and brief, unlike some of those that occur farther east.

===Location and size===

As specified in the designating legislation for the [[Territory of Wyoming]], Wyoming's borders are lines of [[latitude]] [[41st parallel north|41°N]] and [[45th parallel north|45°N]], and [[longitude]] 104°3'W and 111°3'W (27 and 34 west of the [[Washington Meridian]])—a [[geodesic]] quadrangle.<ref>{{cite web|author=Willam J.

Due to surveying inaccuracies during the 19th century, Wyoming's legal border deviates from the true [[latitude]] and [[longitude]] lines by up to {{convert|1/2|mi|km|spell=in}} in some spots, especially in the mountainous region along the [[45th parallel north|45th parallel]].<ref>{{cite web |url=http://www.maa.org/mathtourist/mathtourist_08_30_07.html |title=Rectangular States and Kinky Borders |author=Ivars Peterson |access-date=December 14, 2008 |url-status=dead |archive-url=https://web.archive.org/web/20080705160310/http://www.maa.org/mathtourist/mathtourist_08_30_07.html |archive-date=July 5, 2008}}</ref> Wyoming is bordered on the north by [[Montana]], on the east by [[South Dakota]] and [[Nebraska]], on the south by [[Colorado]], on the southwest by [[Utah]], and on the west by [[Idaho]]. It is the tenth largest state in the United States in total area, containing {{convert|97814|sqmi|km2}} and is made up of 23 counties. From the north border to the south border, it is {{convert|276|mi|km}}; and from the east to the west border is {{convert|365|mi|km}} at its south end and {{convert|342|mi|km}} at the north end.

===Natural landforms===
====Mountain ranges====
[[File:Barns grand tetons.jpg|thumb|[[Teton Range]]]]
[[File:Cattle Drive near Pinedale, WY (14963962303).jpg|thumb|[[Green River (Colorado River tributary)|Green River]] valley]]

The [[Great Plains]] meet the [[Rocky Mountains]] in Wyoming. The state is a great [[plateau]] broken by many [[mountain range]]s. Surface elevations range from the summit of [[Gannett Peak]] in the [[Wind River Range|Wind River Mountain Range]], at {{convert|13804|ft|m}}, to the [[Belle Fourche River]] valley in the state's northeast corner, at {{convert|3125|ft|m}}. In the northwest are the [[Absaroka Range|Absaroka]], [[Owl Creek Mountains|Owl Creek]], [[Gros Ventre Range|Gros Ventre]], [[Wind River Range|Wind River]], and the [[Teton Range|Teton]] ranges. In the north central are the [[Big Horn Mountains]]; in the northeast, the [[Black Hills]]; and in the southern region the [[Laramie Mountains|Laramie]], [[Medicine Bow Mountains|Snowy]], and [[Sierra Madre Range (Wyoming)|Sierra Madre]] ranges.

The Snowy Range in the south-central part of the state is an extension of the Colorado [[Rocky Mountains|Rockies]] both in geology and in appearance. The Wind River Range in the west central part of the state is remote and includes more than 40 mountain peaks in excess of {{convert|13000|ft|m|abbr=on}} tall in addition to [[Gannett Peak]], the highest peak in the state. The Bighorn Mountains in the north-central portion are somewhat isolated from the bulk of the Rocky Mountains.

The Teton Range in the northwest extends for {{convert|50|mi|km}}, part of which is included in [[Grand Teton National Park]]. The park includes the [[Grand Teton]], the second-highest peak in the state.

The [[Continental Divide]] spans north–south across the central portion of the state. Rivers east of the divide drain into the [[Missouri River Basin]] and eventually the [[Gulf of Mexico]]. They are the [[North Platte River|North Platte]], [[Wind River (Wyoming)|Wind]], [[Bighorn River|Bighorn]], and [[Yellowstone River|Yellowstone]] rivers. The [[Snake River]] in northwest Wyoming eventually drains into the [[Columbia River]] and the Pacific Ocean, as does the [[Green River (Colorado River)|Green River]] through the [[Colorado River]] Basin.

The Continental Divide forks in the south-central part of the state in an area known as the [[Great Divide Basin]] where water that precipitates onto or flows into it cannot reach an ocean—it ''all'' sinks into the soil and eventually evaporates.

Several rivers begin in or flow through the state, including the Yellowstone River, Bighorn River, Green River, and the Snake River.

====Basins====
Much of Wyoming is covered with large basins containing different eco-regions, from shrublands to smaller patches of desert.<ref name=Wyo-basins>{{cite web|url=http://www.landscope.org/explore/natural_geographies/ecoregions/Wyoming%20Basins/|publisher=Landscope|date=June 26, 2012|access-date=March 11, 2021|archive-url=https://web.archive.org/web/20200226072841/http://www.landscope.org/explore/natural_geographies/ecoregions/Wyoming%20Basins/|archive-date=February 26, 2020|url-status=live| title= Wyoming Basins Ecoregion }}</ref> Regions of the state classified as basins contain everything from large geologic formations to sand dunes and vast unpopulated spaces.<ref name=Ecoregions-Wyoming>{{cite web|url=https://hort.purdue.edu/newcrop/cropmap/ecoreg/descript.html#18|website=hort.purdue.edu|publisher=[[Purdue University]]|date=April 1, 2000|access-date=March 9, 2021|archive-url=https://web.archive.org/web/20210211032359/https://hort.purdue.edu/newcrop/cropmap/ecoreg/descript.html|archive-date=February 11, 2021|url-status=live| title=Level III Ecoregions of the Continental United States}}</ref> Basin landscapes are typically at lower elevations and include rolling hills, valleys, mesas, terraces and other rugged terrain, but also include natural springs as well as rivers and artificial reservoirs.<ref name=epaEcoregionsofWyoming>{{cite web|url=ftp://newftp.epa.gov/EPADataCommons/ORD/Ecoregions/wy/wy_front.pdf|publisher=[[EPA]]|date=Jan 1, 2004|access-date=March 9, 2021|title=Wyoming Eco-Regions|archive-date=May 9, 2022|archive-url=https://web.archive.org/web/20220509200704/ftp://newftp.epa.gov/EPADataCommons/ORD/Ecoregions/wy/wy_front.pdf|url-status=live}}</ref> They have common plant species such as various subspecies of [[Artemisia tridentata|sagebrush]], [[juniper]] and grasses such as [[Agropyron|wheatgrass]], but basins are known for their diversity of plant and animal species.<ref name=Wyo-basins/>

====Islands====
{{Main list|List of islands of Wyoming}}

Wyoming has 32 named islands; the majority are in [[Jackson Lake (Wyoming)|Jackson Lake]] and [[Yellowstone Lake]], within [[Yellowstone National Park]] in the northwest portion of the state. The [[Green River (Colorado River)|Green River]] in the southwest also contains a number of islands.
