Weather in September
Temperature
The arrival of September corresponds with a minor reduction in the average high-temperature, down from August's hot 90.5°F (32.5°C) to a warm 85.1°F (29.5°C). Cameron Park anticipates a stark contrast in temperature during September nights, with an average low of 56.5°F (13.6°C).Heat index
During September, the heat index is calculated to be 84.2°F (29°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for 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.
