Weather in September
Temperature
The shift from August to September coincides with a small decrease in the average high-temperature, down to a still hot 86.7°F (30.4°C) from 92.8°F (33.8°C). Brown Springs measures a considerable dip from daytime highs with an average low-temperature of 64.9°F (18.3°C) during September.Heat index
September's heat index is appraised at a sweltering 96.8°F (36°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
