When the headline for this monthly report alludes to hazy May skies that were frequently overhead, you know it was a quiet period weather-wise across the Garden State. Such was the case during the middle two weeks of May and at month’s end, with smoke from wildfires in western Canada frequently passing well overhead, followed by smoke from fires in Nova Scotia and a few in NJ. Otherwise, May temperatures were cooler than normal, and rainfall sparse.

What can you say about a month that began with a swarm of tornadoes, finished with flooding rain, and in between, featured record heat, wildfires, and increasing drought concerns? Best to say that it was an odd one! Fitting this theme, the statewide average temperature of 55.4° was 3.9° above the 1991–2020 normal. This ranks as the third warmest April on record (since 1895) only behind 2017 and 2010 for top honors (Table 1). April was the fifth month of the past ten ranking in the top 10, joining July (#7), August (#1), January (#1), and February (#5; Figure 1).

While March temperatures came in above normal, they were not nearly as anomalously mild as those seen in January and February. This quelled concerns that an early blooming season might arise, one that could result in damaged vegetation had an early bloom been followed by an unseasonable cold spell. The average March temperature across NJ was 42.1°. This was 1.2° above the 1991–2020 normal and ranks as the 30th mildest March since 1895. The average maximum temperature of 52.2° was 1.3° above normal, ranking 37th mildest.

Abnormal conditions were seemingly the norm cross the Garden State during the second month of 2023 and, for that matter, during much of the winter (December–February). More on winter later in this report. First, focusing on February, milder-than-normal temperatures and limited snowfall were the rule, a short-lived frigid blast was followed by 70° warmth, and the most notable February tornado of at least the past 74 years touched down.

January 2023 was unlike most any first month of the year a New Jersey resident has experienced. Temperatures were similar to those normally seen in March and accumulating snowfall was meager in the north and non-existent further south. NJ weather was more like that of the piedmont of North and South Carolina at this time of year. The statewide average temperature of 41.0° was 9.3° above the 1991–2020 normal and ties with 1932 as the mildest January since records commenced in 1895 (Table 1). The average high of 48.9° was 8.6° above normal, ranking 2nd mildest.

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!

For the 14th consecutive year, we in the state climate office have evaluated the myriad daily, monthly, and annual observations gathered across New Jersey during the course of the year to choose what we feel were the most significant and impactful 10 weather and climate events of 2022. More about each event can be found in the monthly narratives posted on our website.

Last month’s report spoke of how “classic” the weather was during October. November’s weather could be classified as being anything but such. The month began with perhaps the warmest first ten days of November on record in the Garden State, an interval that ranked up there with early November 2020. Then came winter-like temperatures for about ten days leading up to Thanksgiving before the month ended on a closer-to-normal note.

There are years when many say that New Jersey didn’t experience “classic” fall weather. This October is not one of those years, as the month included rain, wind, and coastal flooding from the persistent remnants of a hurricane, many locations received their first frost and freezing temperatures to end the growing season, and there were days with a cloud-free deep-blue sky. October certainly showed its true fall colors.
