Heat index

September's heat index is appraised at a life-threatening hot 46°C (114.8°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
Note that heat index values are valued for light wind and location in the shade. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

UV index

March through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for the ordinary person.
Note: A daily maximum UV index of 7 in September translates into the following instructions:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. 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. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
