Weather in September

September's average heat index is appraised at a life-threatening hot 46°C (114.8°F). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.Understand that the heat index values take into account shaded locations and mild winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
