Weather in July

July is typically the hottest month in Tulsa, Oklahoma with only August giving close competition. There are similarities in weather behaviour between June and July, still, July shines forth as slightly "more" in every aspect. The peak temperatures often soar beyond 90°F (32.2°C), occasionally causing discomfort due to high humidity. Although the number of rainfall days drop marginally from June, it does not have a significant effect on the overall weather. The wind too slows down its pace, further amplifying the hot weather feel.

Temperature

The month of July sees the highest average temperatures, reaching 91.2°F (32.9°C) at the peak and 72.3°F (22.4°C) at the low.

Heat index

The heat index value during July is calculated to be an extremely hot 109.4°F (43°C). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
