Weather in August
Temperature
August is marked by an average high-temperature of a warm 85.5°F (29.7°C), almost identical to the preceding month. In the month of August, an average of 66.4°F (19.1°C) marks the low-temperature.Heat index
During August, the heat index is appraised at a sweltering 96.8°F (36°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.The metrics for the heat index are tailored for both shady environments and light winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
