Weather in September
Temperature
With September's arrival, Willowcrest's weather records an average high-temperature of a warm 85.3°F (29.6°C), marking little difference from August's 89.8°F (32.1°C). Willowcrest's temperature tends to fall to an average low of 66°F (18.9°C) during the nights of September.Heat index
September's average heat index is evaluated at a fiery hot 95°F (35°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
