Weather in August

August continues on from July, basking in the full glory of the Texas summer. The heatwave continues, with 95.7°F (35.4°C) recorded as the highest temperature for August, slightly surpassing the previous month. Aside from the daytime heat, evening activities remain enjoyable due to relatively cooler temperatures. The relative humidity is somewhat lower during this time, adding to the comfort level.

Temperature

August, marked by an average high-temperature of 95.7°F (35.4°C) and a low-temperature of 75.9°F (24.4°C), is the warmest month.

Heat index

August's mean heat index is appraised at a blisteringly hot 111.2°F (44°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
