Weather in August
Temperature
August brings an average high-temperature of a warm 85.6°F (29.8°C), showing a slight difference from July's 87.4°F (30.8°C). August brings an average low-temperature of 68.2°F (20.1°C) to Lewisdale.Heat index
In August, the average heat index is computed to be a very hot 95°F (35°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. 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 particularly relevant to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
