Heat index

In September, the heat index is estimated at a fiery hot 37°C (98.6°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

The average relative humidity in September is 85%.

UV index

Note: An average UV index of 7 in September transforms into this advice:
Ward off overexposure. Defence against solar harm is crucial. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
