Weather in September
Temperature
As September begins, there is a minor decrease in the average high-temperature, softly falling from 93.7°F (34.3°C) in August to a still hot 87.3°F (30.7°C). Throughout the month of September, Deport expects an average low of 67.1°F (19.5°C).Heat index
In September, the average heat index is calculated to be a sweltering 96.8°F (36°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
