Weather in August
Temperature
The beginning of August records an average high-temperature of a still hot 90.1°F (32.3°C), almost echoing the conditions of the previous month. August brings with it a nighttime average temperature of 70.9°F (21.6°C).Heat index
In August, the average heat index is evaluated at an extremely hot 107.6°F (42°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
