Weather in September
Temperature
As Quinlivan transitions from August to September, the average high-temperatures adjust to a still hot 86.9°F (30.5°C), nearly the same as the previous 90.3°F (32.4°C). Quinlivan observes an average low-temperature of 68°F (20°C) during September.Heat index
For September, the heat index is computed to be a sweltering 102.2°F (39°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Sunshine

The average daily maximum UV index in September is 6. A UV Index value of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for ordinary individuals.Note: A daily high UV index of 6 in September leads to these guidelines:
Resist overexposure. Safeguarding from solar damage is indispensable. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
