Weather in August
Temperature
The onset of August brings with it an average high-temperature of a moderately hot 85.6°F (29.8°C), showing a negligible variation from the month before. Throughout August, Julien Hill records an average temperature of 66°F (18.9°C) at night.Heat index
The heat index value during August is estimated at a fiery hot 96.8°F (36°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. 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 quite important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
