Heat index

The heat index value during September is calculated to be a sweltering 36°C (96.8°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

The average relative humidity in September is 70%.

UV index

The months with the highest UV index are April through September, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: A typical high UV index of 6 in September suggests the following recommendations:
Take precautions against overexposure. Fair-skinned people may get burned in less than 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. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
