Weather in September

September, the first month of the autumn in Frost, is still a hot month, with an average temperature ranging between max 88.3°F (31.3°C) and min 70°F (21.1°C).

Temperature

September observes an average high-temperature of a still tropical 88.3°F (31.3°C), marking an insignificant difference from August's 91.9°F (33.3°C). Frost's temperature drops to an average low of 70°F (21.1°C) during the nights of September.

Heat index

The heat index for September is appraised at a blistering 105.8°F (41°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
