Weather in August
Temperature
In High Island, the month of August is known for its highest average temperatures, reaching a high of 91°F (32.8°C) and a low of 77.5°F (25.3°C).Heat index
The average heat index in August is evaluated at a blazing hot 113°F (45°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Experience reduced UV exposure by about half when donning a wide-brim hat.
