Weather in September
Temperature
With the onset of September, the average high-temperature registers at a still hot 87.6°F (30.9°C), subtly different from August's 91°F (32.8°C). An average low-temperature of 73°F (22.8°C) is observed during the September nights.Heat index
In September, the heat index is appraised at a torrid 102.2°F (39°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.The metrics for the heat index are tailored for both shady environments and light winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
