A North and Central Jersey winter rides the rain-snow line: moderate snow, mixed storms and frequent freeze-thaw, colder inland. Here's how a typical season tends to go. Any given year can differ.

Snowfall and freeze-thaw

Place	Average seasonal snowfall	Freeze-thaw days a year
Newark	31.5 in	57.4
Trenton	26.6 in	71.8

Snowfall: NOAA NCEI 1991–2020 normals.¹ Freeze-thaw days: our count of days with a high above 32°F and a low below 32°F in NOAA GHCN-Daily records, 1991–2020 average.²

The season, month by month

November: line up supply

First freezes inland. Pre-buy and fill your pile.

December: mixed storms

Rain-to-snow flips. Treat after the flip, not before.

January to February: the core of winter

Nor'easters and the coldest pavement. Treat leftover ice before the next storm.

March: freeze-thaw

Warm days, cold nights. Watch pile melt refreeze.
