Weather in September
Temperature
Robertsdale experiences an average high-temperature of a still hot 86.9°F (30.5°C) in September, marking an insignificant shift from 89.8°F (32.1°C) in August. Robertsdale witnesses an average low-temperature of 72.7°F (22.6°C) throughout the month of September.Heat index
During September, the heat index is appraised at a torrid 100.4°F (38°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
