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.
