Weather in September
Temperature
Port Orange observes a minor difference in average high-temperatures between August's 89.2°F (31.8°C) and September's 86.4°F (30.2°C). During September, Port Orange consistently records a temperature low averaging a warm 75.9°F (24.4°C).Heat index
For September, the heat index is computed to be a very hot 98.6°F (37°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. 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. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital 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.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
