Stillwater, Oklahoma, is a city located in north-central Oklahoma, USA. It is the county seat of Payne County and home to Oklahoma State University. The geography of Stillwater is characterized by its location in the Great Plains region of the United States, with rolling hills, prairies, and a continental climate. Understanding the geography of Stillwater involves exploring its physical features, climate, and environmental context in detail.

Geographical Location:

Stillwater is located in north-central Oklahoma, approximately 65 miles northeast of Oklahoma City, the state capital, and largest city. It is located within the Cross Timbers ecoregion, an area characterized by a transition zone between the Great Plains and the eastern forests of the United States. The city is bordered by rural areas and small communities, with open prairies extending to the north, east, and west.


The topography of Stillwater and its surrounding areas is relatively flat, with gently rolling hills and plains typical of the Great Plains region. The city is located at an elevation of approximately 935 feet (285 meters) above sea level, providing expansive views of the surrounding landscape.

To the north and east of Stillwater, the terrain gradually rises towards the Ozark Plateau region of northeastern Oklahoma. The hills become more pronounced as they approach the Ozark Highlands, creating a transition zone between the flat plains of the Great Plains and the rugged terrain of the Ozark Mountains.

To the south and west of Stillwater, the land slopes gently towards the Red River Valley, where the terrain becomes flatter and more open. The Red River Valley is characterized by its fertile soils and agricultural fields, which support a variety of crops and farming activities.


The primary waterway in Stillwater is the Stillwater Creek, a tributary of the Cimarron River. Stillwater Creek flows through the city from west to east, eventually joining the Cimarron River to the east of Stillwater. The Cimarron River is a major tributary of the Arkansas River, which flows through the central United States.

Stillwater Creek serves as an important drainage system for the city, helping to manage stormwater runoff and prevent flooding during heavy rainfall events. The creek also provides habitat for fish, amphibians, and aquatic plants, contributing to the region’s overall biodiversity.

In addition to Stillwater Creek, the city is located near several smaller waterways, including creeks, streams, and drainage ditches that flow into Stillwater Creek and its tributaries. These waterways play a vital role in the region’s hydrology and provide habitat for a variety of wildlife species.


Stillwater experiences a humid subtropical climate, characterized by hot, humid summers and mild, relatively dry winters. The region’s climate is influenced by its location in the central United States, away from the moderating effects of large bodies of water.

Summer temperatures in Stillwater are typically hot, with average high temperatures ranging from the upper 80s to low 90s Fahrenheit (around 31-34 degrees Celsius). However, temperatures can occasionally exceed 100 degrees Fahrenheit (around 38 degrees Celsius) during periods of high heat and humidity. Summer evenings are generally warm and muggy, with overnight lows in the 60s to 70s Fahrenheit (around 15-25 degrees Celsius).

Winter temperatures in Stillwater are mild, with average high temperatures ranging from the upper 40s to low 50s Fahrenheit (around 8-10 degrees Celsius) and lows in the 20s to 30s Fahrenheit (around -1 to 4 degrees Celsius). Snowfall is relatively rare in Stillwater, with the region receiving minimal precipitation during the winter months.

Spring and fall are transitional seasons characterized by fluctuating temperatures and changing weather patterns. These seasons offer mild weather and moderate temperatures, making them ideal times to explore outdoor activities and events in Stillwater.


Stillwater receives moderate precipitation throughout the year, with the majority of rainfall occurring during the spring and summer months. Annual precipitation totals in Stillwater average around 35 to 40 inches (around 89 to 102 centimeters), with most of the precipitation falling as rain during the warmer months.

Thunderstorms are common in Stillwater, particularly during the spring and summer months when atmospheric instability and moisture combine to produce convective storms. These storms can bring heavy rain, strong winds, hail, and occasional lightning, posing risks to outdoor activities and agriculture in the region.

Natural Hazards:

Stillwater is susceptible to a variety of natural hazards, including severe weather events such as thunderstorms, tornadoes, and occasional flooding. Thunderstorms are a common occurrence in the region, particularly during the spring and summer months, and can bring heavy rain, strong winds, hail, and occasional lightning.

Tornadoes are a potential hazard in Stillwater, as the region lies within Tornado Alley, a region of the central United States known for frequent tornado activity. While tornadoes are relatively rare in Stillwater, they can occur during severe weather outbreaks and pose risks to residents and property in the area.

Flooding is another potential hazard in Stillwater, particularly along the banks of Stillwater Creek and its tributaries. Heavy rainfall, snowmelt, and runoff can cause the creek to overflow its banks, posing risks to low-lying areas and infrastructure in the city.

Vegetation and Wildlife:

The natural vegetation of Stillwater and its surrounding areas consists primarily of grasslands, prairies, and woodlands. Native plant species include grasses, wildflowers, and shrubs adapted to the region’s climate and soil conditions.

Stillwater is home to a variety of wildlife adapted to the region’s grasslands, prairies, and woodlands, including mammals, birds, reptiles, and amphibians. Common mammal species include deer, coyotes, rabbits, and various species of rodents. Birdwatchers can spot a wide range of avian species, including songbirds, raptors, waterfowl, and migratory birds passing through the region.

The region’s grasslands, prairies, and woodlands provide important habitat for wildlife, supporting a variety of species adapted to central Oklahoma ecosystems. Riparian areas along Stillwater Creek and its tributaries provide habitat for fish, amphibians, and aquatic plants, contributing to the region’s overall biodiversity.

Environmental Conservation:

Stillwater is committed to environmental conservation and sustainable development practices aimed at preserving its natural resources and promoting responsible stewardship of the environment. The city collaborates with local organizations, government agencies, and community stakeholders to develop and implement initiatives that support conservation goals and promote environmental awareness.
