Weather in August
Temperature
July's transformation into August witnesses an average high-temperature of a still hot 94.5°F (34.7°C), noting a minor change from the preceding month. During August, the temperature is averaged to a low of 73.8°F (23.2°C) at night.Heat index
In August, the heat index is estimated at a burning hot 125.6°F (52°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
