Weather in September
Temperature
A subtle shift in Seward's weather is observed as August turns into September, with the average high temperature reducing from a tropical 90.1°F (32.3°C) to a warm 82°F (27.8°C). An average low-temperature of 61.7°F (16.5°C) is recorded in the month of September in Seward, Kansas.Heat index
September's average heat index is computed to be 84.2°F (29°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
