Weather in December
Temperature
With December's arrival, Haskell sees a decrease in average high-temperatures, moving from a mild 59.5°F (15.3°C) in November to a frosty 49.1°F (9.5°C). Nighttime temperatures hover around an average low of 34.7°F (1.5°C) in December.Humidity
In December, the average relative humidity is 71%.Rainfall
February and December are months with the least rain when the rain falls for 4.5 days and typically aggregates up to 0.47" (12mm) of rain.Snowfall
Months with snowfall are January through March and December. December is the first month it typically snows. Throughout December, in the average 1.5 snowfall days, it receives 0.08" (2mm) of snow. In Haskell, during the entire year, snow falls for 5 days and aggregates up to 0.63" (16mm) of snow.Daylight
With an average of 9h and 48min of daylight, December has the shortest days of the year.On the first day of the month, sunrise is at 7:14 am and sunset at 5:09 pm. On the last day of December, sunrise is at 7:32 am and sunset at 5:19 pm CST.
Sunshine
December has the least sunshine of the year, with an average of 5.6h of sunshine.UV index
December is the month with the lowest UV index, with an average maximum UV index of 2. A UV Index reading of 2, and below, represents a minimal health vulnerability from exposure to the Sun's UV radiation for average individuals.Note: The maximum UV index, 2 during December, leads to the following recommendations:
Extended sunlight exposure does not pose significant problems for most people, except for children, infants, and people with fair skin who always need shielding. The best time to avoid the Sun's harmful UV radiation is during midday when it's most potent. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays. Alert! The snow's reflection can amplify the UV radiation of the Sun nearly twice.
