Weather in September
Temperature
September is marked by a subtle drop in average high-temperatures, transitioning from a hot 90.9°F (32.7°C) in August to a warm 84.2°F (29°C). During September, the temperature is averaged to a low of 64°F (17.8°C) at night.Heat index
The heat index value for September is computed to be a tropical 91.4°F (33°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Humidity
The average relative humidity in September is 70%.Rainfall
In Haskell, in September, during 8.1 rainfall days, 0.63" (16mm) of precipitation is typically accumulated. In Haskell, during the entire year, the rain falls for 92.3 days and collects up to 9.49" (241mm) of precipitation.Snowfall
In Haskell, snow does not fall in April through November.Daylight
In Haskell, the average length of the day in September is 12h and 23min.On the first day of September, sunrise is at 6:55 am and sunset at 7:49 pm. On the last day of the month, sunrise is at 7:17 am and sunset at 7:07 pm CDT.
Sunshine
In Haskell, the average sunshine in September is 9.1h.UV index
In Haskell, the average daily maximum UV index in September is 5. A UV Index reading of 3 to 5 represents a medium health hazard from exposure to the Sun's UV radiation for ordinary individuals.Note: A daily high UV index of 5 in September leads to these guidelines:
Undertake protective steps - Obligation to safeguard skin and eyes from harm is in place. The Sun is at its harshest during midday; protect yourself by staying in shaded areas and minimizing exposure. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
