During August, the heat index is estimated at a hot 87.8°F (31°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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.
