December/2025 Annual Report
January 7, 2026
Following a cold December and first few days of the month, temperatures rose to above-normal levels through the remainder of the first half of January. Thereafter, a major mid-month atmospheric pattern shift brought Arctic air roaring into the region, and with it several snow events and one of the more persistent cold episodes in recent years lasting through the end of the month.
The first 15 days of January averaged 13° milder than the final 16 days. All told, the statewide January average temperature of 28.0° was 3.7° below the 1991–2020 normal. It ranked as the 42nd coldest since NJ records commenced in 1895 and was the coldest since 2014 and 5th coldest this century. The average high was 36.4°, 3.9° below normal and the 45th coldest, while the average low of 19.6° was 3.6° below normal, ranking 44th coldest.
Despite a soaking rain event early in the month and an impactful late-month winter storm, the monthly statewide precipitation average (rain and melted snow/ice) was below normal at 2.67”. This was 0.82” below average and ranked as the 42nd driest. January snowfall averaged 14.3” across NJ. This was 7.1” above normal and ranks as the 17th snowiest of the past 132 years.
