Weather in August
Temperature
The onset of August notes an average high-temperature of a warm 85.8°F (29.9°C), subtly shifted from July's 86.5°F (30.3°C). August nights observe an average temperature dip to a refreshing 65.1°F (18.4°C).Heat index
The heat index value during August is calculated to be a sweltering 98.6°F (37°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Factoring in the heat index, values are geared towards shaded areas with light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important 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 physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
