Heat index

For September, the heat index is appraised at a sweltering 39°C (102.2°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. 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. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
