Weather in August
Temperature
Justin records the warmest temperatures in August, averaging a high of 95.5°F (35.3°C) and a low of 75.6°F (24.2°C).Heat index
For most parts of August, the heat index is appraised at a scorching 111.2°F (44°C). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
