For most parts of September, the heat index is calculated to be a tropical 30°C (86°F). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.In the scope of the heat index, its values resonate with shade and light wind conditions. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Be prepared! The intensity of the Sun's UV radiation can be amplified nearly double due to snow reflection.
