Weather in September
Temperature
With September's arrival, Norfield's weather records an average high-temperature of a still hot 86.7°F (30.4°C), marking little difference from August's 90.3°F (32.4°C). Throughout September, an average low-temperature of 68°F (20°C) is expected in Norfield, Mississippi.Heat index
The heat index for September is estimated at a very hot 100.4°F (38°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
