Weather in September
Temperature
September experiences an average high-temperature of a still hot 87.8°F (31°C), barely different from August's 91.2°F (32.9°C). Burtville records an average nighttime low of 70.3°F (21.3°C) in September.Heat index
The average heat index in September is computed to be an extremely hot 105.8°F (41°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
