Weather in August
Temperature
The advent of August brings an average high-temperature of a still tropical 91.9°F (33.3°C), exhibiting minor difference from the previous month. Optima's average low-temperature for the month of August denotes a significant decline from the daily high, recording at an agreeable 69.8°F (21°C).Heat index
For August, the heat index is evaluated at a very hot 96.8°F (36°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
