Heat index

Throughout September, the heat index is calculated to be a torrid 35°C (95°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
