Weather in September
Temperature
The transition into September is marked with an average high-temperature of a still hot 86.2°F (30.1°C), showing an insignificant shift from August's 90.5°F (32.5°C). Throughout September, the temperature falls to an average low of 75.7°F (24.3°C).Heat index
In September, the average heat index is computed to be a fiery hot 98.6°F (37°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Sunshine

In September, the average daily maximum UV index is 6. A UV Index of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for the ordinary person.Note: The daily maximum UV index of 6 in September interprets into the following advice:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes. Be attentive! The reflective property of snow can nearly double the Sun's UV radiation.
