Seeking Identities:
December 2022 and Annual 2022 Recaps

Dr. David A. Robinson
January 6, 2023

As has so often been the situation in 2022, December’s weather never settled into any persistent pattern. Unless, of course, a pattern of frequent variations constitutes persistence! In any case, it seems appropriate to co-label this combined monthly and annual report as intervals in search of identities!

Looking first at December, the statewide average temperature of 35.5° is 1.1° below the 1991–2020 normal. This ranks as the 44th mildest December dating back to 1895. The statewide average maximum temperature of 44.9° is 0.1° below normal and ranked 31st mildest. The average minimum was 26.1°, which is 2.1° below normal and ranks 54th mildest. North Jersey averaged 33.3° (-0.8°, 36th mildest), south Jersey 36.8° (-1.3°, 49th mildest), and the Jersey coast 37.7° (-1.4°, 50th mildest).

Statewide precipitation averaged 4.76”, which is 0.49” above normal and ranks 35th wettest. North Jersey averaged 4.93” (+0.68”, 32nd wettest), south Jersey 4.68” (+0.40”, 37th wettest), and the Jersey coast 4.49” (+0.13”, 43rd wettest). The wettest locations were in the northeast and along the northern coast, while the northwest and much of the south were on the drier side.
