Weather in September
Temperature
Edison marks the onset of September with an average high-temperature of a still hot 86.2°F (30.1°C), a subtle shift from August's 90.1°F (32.3°C). Edison throughout September, records an average low-temperature of 69.1°F (20.6°C).Heat index
September's heat index is estimated at a fiery hot 96.8°F (36°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

The average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for the ordinary person.Note: The maximum UV index of 6 during September leads to these instructions:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. To best shield against UV radiation, choose sun-safe garments and dependable sunglasses.
