Weather in September
Temperature
The shift into September reveals an average high-temperature of a still hot 88°F (31.1°C), closely mirroring August's climate. In the month of September, Northwood records a consistent average low-temperature of 72.3°F (22.4°C).Heat index
For September, the heat index is evaluated at a blisteringly hot 105.8°F (41°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.
