Weather in September
Temperature
As August makes way for September, Robberson's average high-temperature eases from a very hot 100°F (37.8°C) to a hot 93°F (33.9°C). Robberson, during the month of September, experiences an average low-temperature of 77°F (25°C).Heat index
September's heat index is estimated at a blistering 109.4°F (43°C). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
