Heat index

For most parts of September, the heat index is calculated to be a very hot 38°C (100.4°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. 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 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes.

Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
