Weather in September
Temperature
Caroline observes an average high-temperature of a still hot 86.7°F (30.4°C) in September, barely different from 90.1°F (32.3°C) in August. Caroline registers a consistent average low-temperature of 70.7°F (21.5°C) during September.Heat index
The heat index value during September is computed to be a very hot 102.2°F (39°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly meaningful for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

In Caroline, the average daily maximum UV index in September is 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the ordinary person.Note: The UV index of 6 in September translates into these instructions:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear. Keep in mind! Snow's reflective quality can nearly double the intensity of the Sun's UV radiation.
