Weather in August

The average heat index in August is appraised at a hot 89.6°F (32°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
