So much for March flipping from lion to lamb or vice versa. March 2024 was often a lion throughout, with frequent roaring winds and multiple rain events producing a near-record monthly precipitation total and occasional flooding. The first half of the month ran at a record-warm pace, the monthly average later to be tempered by a second half that was cooler than the first. Still, the month emerged as the 9th mildest on record. Befitting the overall mild conditions, snowfall was scarce to non-existent.

It was a wet December, of this there is no doubt. In fact, it was New Jersey’s wettest 12th month on record, dating back to 1895. On multiple occasions, rainfall arrived in multiple-inch increments, leading to episodes of minor to major stream and river flooding. Though hardly maliciously, Mother Nature certainly left the tap flowing far too long and often!

Overview

The moist and mild pattern of late spring and early summer has left the Garden State quite green. There is nothing new to this pattern, as the first six months of 2019 totaled 27.22” of rain and melted snowfall, some 4.92” above the 1981–2010 mean, and a 49.0° average temperature, which is 1.3° above average. Each of these ranks 13th highest of the past 125 years.

December Overview

It is appropriate that the weather of last month of 2018 was rather similar to many earlier months in the year. Statewide, precipitation was above average for the 10th month of 2018 and the temperature was above average for the 8th month. This resulted in the year being the wettest on record and the 11th warmest since statewide observations began being calculated in 1895. More on this later in the report.
