Weather in September
Temperature
The transition into September marks the average high-temperature at a still hot 86°F (30°C), differing minimally from August's 89.6°F (32°C). September in Seadrift is characterized by a steady nighttime low-temperature of 77.4°F (25.2°C).Heat index
The average heat index in September is estimated at a fiery hot 96.8°F (36°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.In reference to the heat index, it's for places in shade and with a slight wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
