For most parts of September, the heat index is evaluated at a blazing hot 46°C (114.8°F). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. 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. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Take the necessary steps to protect yourself; unprotected skin and eyes are vulnerable to damage. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
