Weather in September
Temperature
The shift from August to September is characterized by an average high-temperature of a still hot 87.1°F (30.6°C), not significantly different from the 90.1°F (32.3°C) of August. Bell experiences an average nighttime temperature of 72.3°F (22.4°C) in the month of September.Heat index
For most parts of September, the heat index is calculated to be a torrid 102.2°F (39°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. 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 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
