Weather in August
Temperature
The start of August marks an average high-temperature of a warm 85.5°F (29.7°C), hardly distinguishable from the conditions in July. The average nighttime temperature lowers to an enjoyable 64.6°F (18.1°C) throughout August.Heat index
August's heat index is evaluated at a torrid 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. 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.
