The Sussex County Snow Belt is a microclimate snowbelt region in Sussex County, New Jersey in northwest New Jersey. The belt is part of New Jersey's Northern Climate Zone, which receives about forty to fifty inches of snow per year. The snow belt generally receives more snow than the rest of Northern New Jersey and the Northern Climate Zone because of slight orographic lift of the Kittatinny Ridge, which increases humidity and precipitation.
The snow belt is in an area of Great Valley in Sussex County, east of the Kittatinny Ridge roughly from Newton to Vernon. Two of New Jersey's three ski facilities are in this snow belt (Mountain Creek and Hidden Valley).
