Weather in September
Temperature
Oyster Creek in September witnesses an average high-temperature of a warm 85.5°F (29.7°C), indicating a slight variation from August's 88.9°F (31.6°C). Oyster Creek maintains a near steady average temperature of 77.2°F (25.1°C) during the nights of September, demonstrating little drop from daytime highs.Heat index
Throughout September, the heat index is estimated at a very hot 95°F (35°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
