The heat index in July is computed to be a tropical 89.6°F (32°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual.

Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
