The heat index value for August is calculated to be a tropical 89.6°F (32°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children.
