Weather in September
Temperature
Samson records a slight change with September's average high-temperatures adjusting to a still hot 87.1°F (30.6°C) from August's 90.7°F (32.6°C). During September nights, Samson witnesses a consistent average temperature of 69.6°F (20.9°C).Heat index
In September, the heat index is calculated to be a torrid 100.4°F (38°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 are especially crucial for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
