August weather forecast
Oklahoma City, OK

August maintains the summer temperature consistency in Oklahoma City, offering similar weather conditions to July. As the city enjoys the last month of summer, residents relish in the extended daylight hours offered, which is conducive for a wide variety of outdoor activities. Despite the high temperatures, lower rainfall and relative humidity add a touch of comfort to the month. As autumn approaches, there's a feeling of anticipation in the air while summer continues to take center stage. Notably, conditions in August range from a maximum of 92.8°F (33.8°C) to a minimum temperature of 71.6°F (22°C).

Temperature

The beginning of August reveals an average high-temperature of a still hot 92.8°F (33.8°C), showing minimal deviation from the previous month. In Oklahoma City, August is marked by an average low-temperature of 71.6°F (22°C).

Heat index

For August, the heat index is appraised at a blisteringly hot 107.6°F (42°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
