Weather in September
Temperature
The shift to September in Ridgeland signals an average high-temperature of a still hot 87.3°F (30.7°C), subtly varied from August's 91.8°F (33.2°C). Throughout the month of September, the nighttime temperature dips to an average of 67.5°F (19.7°C).Heat index
September's average heat index is evaluated at a very hot 100.4°F (38°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
