Weather in August

The advent of August brings an average high-temperature of a warm 85.6°F (29.8°C), exhibiting minor difference from the previous month. In Crestwood, August nights cool down to an average of 66.9°F (19.4°C).Heat index
In August, the heat index is appraised at a torrid 96.8°F (36°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Heat index values are typically calculated for conditions of shade and a light breeze. 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 found by incorporating humidity levels into the air temperature measurement. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. 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 is at risk of dehydration and related complications when it fails to shed excessive heat.
