Weather in August
Temperature
August welcomes an average high-temperature of a warm 85.6°F (29.8°C), not much different from the preceding month. The temperature dips to an average of 66.2°F (19°C) during August nights.Heat index
During August, the heat index is computed to be a fiery hot 96.8°F (36°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Be aware that heat index ratings are designed for shaded locations and minor breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
