Weather in September
Temperature
The advent of September denotes an average high-temperature of a moderately hot 85.1°F (29.5°C), subtly different from August's 86.7°F (30.4°C). Manalapan observes a minimal variance in temperature, with a consistent average low of 80.1°F (26.7°C) during the nights of September.Heat index
The heat index value during September is evaluated at a fiery hot 95°F (35°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
