Weather in September
Temperature
Spring's progression into September involves a minor drop in the average high-temperature, slightly receding from a fiery hot 95.9°F (35.5°C) in August to a hot 89.6°F (32°C). In the month of September, Spring experiences an average low-temperature of 72.1°F (22.3°C).Heat index
September's mean heat index is computed to be a scorching 105.8°F (41°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
Humidity
In September, the average relative humidity is 72%.Rainfall
In Spring, during September, the rain falls for 18.9 days and regularly aggregates up to 3.66" (93mm) of precipitation. Throughout the year, in Spring, there are 173.5 rainfall days, and 32.91" (836mm) of precipitation is accumulated.Snowfall

In Spring, the average length of the day in September is 12h and 20min.On the first day of September, sunrise is at 6:59 am and sunset at 7:43 pm. On the last day of the month, sunrise is at 7:14 am and sunset at 7:07 pm CDT.
Sunshine
In September, the average sunshine in Spring is 8.5h.UV index
In Spring, the average daily maximum UV index in September is 6. A UV Index value of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for ordinary individuals.Note: An average maximum UV index of 6 in September leads to these recommendations:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
