Heat index

During June, the heat index is computed to be a tropical 30°C (86°F). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.
Always consider that heat index estimations are for light winds and places in the shade. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.

Protection is paramount; otherwise, swift harm can come to the skin and eyes. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak.

This also decreases the risk of damage to the immune system.
