Weather in September
Temperature
September's presence records an average high-temperature of a moderately hot 84.9°F (29.4°C), closely mirroring August's climate. Douglas observes an average nighttime low-temperature of 69.1°F (20.6°C) during the month of September.Heat index
In September, the average heat index is estimated at a very hot 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
