Weather in September
Temperature
A minor adjustment in Ladd's average high-temperature is noted with the start of September, touching a moderately hot 85.8°F (29.9°C) from August's 90.7°F (32.6°C). The average temperature drops to a comfortable 66.2°F (19°C) during the night in the month of September.Heat index
September's average heat index is evaluated at a torrid 95°F (35°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Understand that the heat index values take into account shaded locations and mild winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Limit direct exposure to the Sun during these hours. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
