For most parts of July, the heat index is estimated at a tropical 86°F (30°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
