Located in the south-central United States, Oklahoma is known for its extremely hot summers, with a unique climate where both humid heat and dry heat can be felt.
This article explains in detail the causes of Oklahoma’s heat, countermeasures against it, and cooler spots within the state.
[Causes of Heat in Oklahoma]
1. Location at the boundary of humid subtropical and semi-arid climates
- The eastern part of Oklahoma falls under a humid subtropical climate, while the western part is classified as semi-arid, both experiencing high summer temperatures.
- Residents can feel the humid heat in the east and the dry heat in the west.
2. Influx of warm, moist air from the Gulf of Mexico
- In summer, warm, moist air flows into eastern Oklahoma from the Gulf of Mexico, bringing oppressive humidity.
3. Intense sunlight and heatwaves in the dry west
- The dry western region experiences long periods of sunshine, with intense solar radiation pushing temperatures close to 40°C (104°F).
4. Effects of flat terrain and wind
- Much of Oklahoma consists of flat prairie land. While wind is common, heatwaves can easily spread across wide areas.
[Heat Countermeasures]
1. Widespread use of air conditioning
- Air conditioning is common in homes and public facilities, making it essential for heatstroke prevention.
2. Shading and insulation
- Installing blackout curtains and designing homes with insulation helps reduce indoor temperature rises.
3. Hydration and outdoor activity management
- Residents are advised to avoid outdoor activities during the hottest hours (especially in the afternoon) and to stay hydrated with both water and electrolytes.
4. Public cooling centers
- Municipalities provide cool public spaces for people at high risk of heat-related illness.
[Cool Spots in Oklahoma]
1. Highland and forested areas
- Elevated regions such as the Ozark Plateau in the east and the Illinois River Valley tend to stay relatively cool in summer.
2. Areas near rivers and lakes
- The Arkansas River and lake areas near Tulsa offer breezes from the water that bring some relief from the heat.
3. Urban parks and green spaces
- Large parks in cities like Oklahoma City and Tulsa provide shaded areas that help mitigate summer heat.

[Additional Notes]
Oklahoma’s summer climate varies by region: the east experiences humid, muggy heat, while the west suffers from dry, intense heatwaves. Regardless of the type of heat, taking precautions against heat-related illnesses is essential.
