The heat index value during August is estimated at a hot 87.8°F (31°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. 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 particularly relevant to babies and toddlers. Youngsters typically face more danger than adults since they sweat less.
