Weather in September

September, the first month of the autumn in Newton, is still a warm month, with an average temperature fluctuating between 69.1°F (20.6°C) and 85.8°F (29.9°C).

Temperature

The transition into September is marked with an average high-temperature of a moderately hot 85.8°F (29.9°C), showing an insignificant shift from August's 90°F (32.2°C). During September, Newton records an average temperature of 69.1°F (20.6°C) at night.

Heat index

The heat index in September is calculated to be a sweltering 96.8°F (36°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Factoring in the heat index, values are geared towards shaded areas with light breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
