Weather in September
Temperature
The transition into September subtly indicates a reduction in the average high-temperature, down to a hot 87.6°F (30.9°C) from August's very hot 95.5°F (35.3°C). Frost reports an average low-temperature of 70°F (21.1°C) during the nights of September.Heat index
The heat index value for September is estimated at a fiery hot 96.8°F (36°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

In Frost, in September, during 15.6 rainfall days, 2.83" (72mm) of precipitation is typically accumulated. Throughout the year, there are 146.4 rainfall days, and 32.72" (831mm) of precipitation is accumulated.Snowfall

Sunshine
In Frost, the average sunshine in September is 8.5h.UV index
In September, the average daily maximum UV index is 6. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for ordinary individuals.Note: An average maximum UV index of 6 in September leads to these recommendations:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
