Weather in September
Temperature
The onset of September notes an average high-temperature of a warm 85.3°F (29.6°C), subtly shifted from August's 89.6°F (32°C). In the month of September, Roberta records a consistent average low-temperature of 67.8°F (19.9°C).Heat index
The heat index value for September is calculated to be a very hot 95°F (35°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
