Weather in September
Temperature
The move into September indicates a slight reduction in the average high-temperature, down from August's hot 88.3°F (31.3°C) to a warm 81.1°F (27.3°C). Newton experiences an average low-temperature of 61.9°F (16.6°C) in month of September.Heat index
September's average heat index is estimated at 84.2°F (29°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
