Weather in September
Temperature
In September, the average high-temperature marginally decreases from a tropical 90.9°F (32.7°C) in August to a warm 84.2°F (29°C). During September, Haskell witnesses a consistent average low-temperature of 64°F (17.8°C).Heat index
The heat index in September is computed to be a hot 91.4°F (33°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Humidity
The average relative humidity in September is 70%.Rainfall
In Haskell, Oklahoma, during September, the rain falls for 8.1 days and regularly aggregates up to 0.63" (16mm) of precipitation. 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 the month, sunrise is at 6:55 am and sunset at 7:49 pm. On the last day of September, 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
The average daily maximum UV index in September is 5. A UV Index value of 3 to 5 symbolizes a moderate health risk from exposure to the Sun's UV rays for the ordinary person.Note: In September, the maximum UV index of 5 translates into these guidelines:
Exercise prevention - Protecting skin and eyes from harm is required. Limiting sun exposure during midday hours helps in reducing the harmful effects of UV radiation. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
