Weather in September
Temperature
September's arrival aligns with a minor decrease in average high-temperatures, from August's 94.8°F (34.9°C) to a still hot 88.5°F (31.4°C). New London sees an average low-temperature of 68°F (20°C) during September.Heat index
The heat index value during September is estimated at a sweltering 100.4°F (38°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
