Weather in September
Temperature
Haskell records a mild change in average high-temperature during September, easing from a tropical 91.6°F (33.1°C) in August to a moderately hot 85.3°F (29.6°C). Throughout September, the average low-temperature records at a refreshing 64.8°F (18.2°C).Heat index
The heat index for September is estimated at a sweltering 95°F (35°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
Humidity
In September, the average relative humidity 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
In Haskell, Arkansas, snow does not fall in April through November.Daylight
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 Haskell, the average sunshine in September is 9.5h.UV index
In Haskell, the average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high health risk from unprotected exposure to Sun's UV rays for average individuals.Note: The maximum daily UV index of 6 in September converts into the following recommendations:
Exercise precautions and adapt sun safety practices. Defence against skin and eye affliction is paramount. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
