Weather in August
Temperature
August ushers in an average high-temperature of a still warm 82°F (27.8°C), aligning closely with the preceding month. The average temperature drops to a comfortable 63.5°F (17.5°C) during the night in the month of August.Heat index
For August, the heat index is evaluated at a hot 87.8°F (31°C). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.Heat index determinations are made taking into account the shade and light air movements. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
