Weather in August
Temperature
Keller's August weather, marked by an average high temperature of 95.9°F (35.5°C) and an average low temperature of 75.7°F (24.3°C), is the warmest in the year.Heat index
The average heat index in August is calculated to be a blistering 111.2°F (44°C). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.In the scope of the heat index, its values resonate with shade and light wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
