Weather in September
Temperature
Waggaman's weather in September, with an average high-temperature of a still hot 86.5°F (30.3°C), subtly shifts from August's 88.7°F (31.5°C). Waggaman observes an average nighttime low-temperature of 75°F (23.9°C) during the month of September.Heat index
For most parts of September, the heat index is appraised at a fiery hot 98.6°F (37°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
