Weather in August
Temperature
The onset of August notes an average high-temperature of a still hot 86.7°F (30.4°C), subtly shifted from July's 88°F (31.1°C). An average low-temperature of 65.7°F (18.7°C) is anticipated throughout the nights during August.Heat index
In August, the average heat index is calculated to be a torrid 100.4°F (38°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Understanding the heat index involves considering values for shaded locales with light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
