Weather in September
Temperature
The arrival of September denotes a barely perceptible change in the average high-temperatures to a warm 84.7°F (29.3°C) from August's 88.9°F (31.6°C). September's average low-temperature reading in Grove Lakes settles at an agreeable 68.2°F (20.1°C).Heat index
For September, the heat index is computed to be a sweltering 95°F (35°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
