Weather in September
Temperature
Elwood Park's weather in September, with an average high-temperature of a still hot 86.9°F (30.5°C), subtly shifts from August's 88.5°F (31.4°C). An average low-temperature of 77.4°F (25.2°C) marks the month of September.Heat index
For most parts of September, the heat index is appraised at a very hot 100.4°F (38°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.In reference to the heat index, it's for places in shade and with a slight wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 hold particular significance for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
