Heat index

The heat index value during September is evaluated at a blisteringly hot 43°C (109.4°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes.

Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
