Weather in December
Temperature
Haskell in December experiences a subtle temperature decline, with average high-temperatures reducing from a chilly 49.8°F (9.9°C) in November to an icy 40.1°F (4.5°C). December witnesses an average nighttime temperature of 28.9°F (-1.7°C) in Haskell.Humidity
February and December, with an average relative humidity of 80%, are the most humid months.Rainfall
In Haskell, New Jersey, in December, during 9.1 rainfall days, 2.48" (63mm) of precipitation is typically accumulated. In Haskell, during the entire year, the rain falls for 148.6 days and collects up to 26.18" (665mm) of precipitation.Snowfall
Months with snowfall in Haskell are January through May, October through December. In Haskell, in December, during 4.1 snowfall days, 2.6" (66mm) of snow is typically accumulated. In Haskell, during the entire year, snow falls for 25.5 days and aggregates up to 15.83" (402mm) of snow.Daylight
With an average of 9h and 18min of daylight, December has the shortest days of the year.On the first day of December in Haskell, sunrise is at 7:03 am and sunset at 4:29 pm. On the last day of the month, sunrise is at 7:22 am and sunset at 4:38 pm EST.
Sunshine
In Haskell, the average sunshine in December is 4.7h.UV index
The months with the lowest UV index are January through March, November and December, with an average maximum UV index of 2. A UV Index reading of 2, and below, represents a minimal health vulnerability from unprotected exposure to Sun's UV rays for the average person.Note: In December, the maximum UV index of 2 translates into these guidelines:
Extended sun exposure is not an issue for the majority. Children, infants, and fair-skinned individuals always need to be protected. Limiting sun exposure during midday hours helps in reducing the harmful effects of UV radiation. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses. Be aware! The intensity of the Sun's UV radiation can be amplified nearly twice due to snow reflection.
