Heat index

During September, the heat index is evaluated at a very hot 38°C (100.4°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for average individuals.
Note: A daily maximum UV index of 7 in September translates into the following instructions:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Always opt for UVA and UVB-resistant sunglasses on radiant days. Attention! The reflection of both water and sand can increase the intensity of UV rays.
