Weather in September
Temperature
September's commencement is accompanied by an average high-temperature of a still hot 87.1°F (30.6°C), diverging marginally from August's 90.9°F (32.7°C). Manack experiences an average low-temperature of 67.5°F (19.7°C) in the month of September.Heat index
For September, the heat index is evaluated at a fiery hot 98.6°F (37°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
