July's heat index is calculated to be a hot 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception.
