Weather in September
The first month of the autumn, September, is also a moderately hot month in Haskell, Arkansas, with temperature in the range of an average low of 64.8°F (18.2°C) and an average high of 85.3°F (29.6°C).Temperature
September signifies a gentle decline in Haskell's average high-temperature, easing from a tropical 91.6°F (33.1°C) in August to a warm 85.3°F (29.6°C). In Haskell, in September, the average low-temperature is a refreshing 64.8°F (18.2°C).Heat index
During September, the heat index is estimated at a torrid 95°F (35°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Observations indicate that the heat index values are for shady locations with light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
Humidity
In Haskell, the average relative humidity in September is 72%.Rainfall
The month with the least rainfall is September, when the rain falls for 11.9 days and typically collects 1.89" (48mm) of precipitation.Snowfall
April through November are months without snowfall.Daylight
In Haskell, the average length of the day in September is 12h and 23min.On the first day of September, sunrise is at 6:44 am and sunset at 7:36 pm. On the last day of the month, sunrise is at 7:04 am and sunset at 6:55 pm CDT.
Sunshine
In September, the average sunshine in Haskell is 9.5h.UV index
In September, the average daily maximum UV index is 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for average individuals.Note: In September, the average maximum UV index of 6 translates into the following recommendations:
Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
