Heat index

The heat index for September is evaluated at a fiery hot 35°C (95°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
