The statewide average precipitation this June was 3.10”. This is 0.91” below the 1981–2010 average and ranks as the 43rd driest of the past 126 Junes. As is typical during the warm season, where the bulk of the rainfall is provided by showers and thunderstorms, totals varied widely from location to location, even at times in close proximity to one another. Monmouth and northern Ocean counties saw the most, totaling over 5.00” in spots, with a secondary maximum in Gloucester County. The Highlands, portions of central NJ, and southern Ocean and Cape May counties saw as little as 1.00–2.00”.

The statewide average temperature of 71.6° was 1.8° above the 1981–2010 normal. This ranks as the 10th warmest, joining four other years this century in the top 10, while being the warmest since 2011.

If you have a sense that April was unusually windy, you are certainly not alone. While long-term wind observations are few across the Garden State and those available suffer from inconsistencies in instrumentation and location, seat-of-the-pants judgment tells us that plenty of air raced crossed the state throughout the month. In fact, the wind gusted to 40 mph or higher at one or more NJWxNet station on 12 days. Of those, seven had gusts from 50–59 mph and an impressive four gusted over 60 mph. The highest network gust of 76 mph occurred at Sea Girt (Monmouth County) on the 21st. There were also reports from other seemingly reliable stations of gusts as high as 82 mph at Island Beach State Park (Ocean) on the 13th.

April precipitation achieved a statewide average of 3.92”. This is 0.07” below the 1981–2010 mean, but given the skewness of the distribution of April rainfall over the past 126 years, it ranks as the 45th wettest. Despite Morris County stations having the highest monthly totals, overall, the north part of the state was driest. The mean of 3.66” was 0.54” below normal and is the 59th driest (68th wettest). The south averaged 4.07”, which is 0.21” above normal and is 40th wettest. The narrow coastal region averaged 4.16”, which is 0.33” above normal and ranks 39th wettest.

March 2020 was the 6th mildest in New Jersey dating back to 1895. Combined with mild rankings of 9th in January and 4th in February, 2020 has started off as the 2nd mildest on record at 5.8° above the 1981–2010 average. The 40.8° average only falls behind 2012’s 41.4°. Six of the ten mildest January–March intervals in the past 126 years have occurred since 2002.

March averaged 46.3° across NJ, which is 5.5° above average. The average maximum of 56.2° (+5.4°) ranked 7th mildest and the minimum of 36.4° (+5.6°) 2nd mildest. Anomalies were +5.8° in both the southern (47.9°) and coastal (47.7°) divisions, ranking 6th and 4th mildest, respectively, and +5.0° in the north (43.7°), ranking 9th mildest. As a result of the premature warmth, vegetation green up across the state was at least two weeks earlier than normal.

Following on the heels of the 8th mildest January on record, February 2020 entered the books as the 3rd mildest since records began in 1895. The 39.2° average was 5.7° above the 1981–2010 mean. The northern climate division of the state averaged 36.2° (+5.2°; 6th mildest), the south was 41.0° (+6.1°; 3rd mildest), and the coastal division was 41.2° (+5.7°; 3rd mildest). Average minimum temperatures ranked 2nd mildest for the state, while average maximums ranked 8th mildest. To place February 2020 in some perspective, it was just 1.6° below the 1981–2010 March average of 40.8° and only 0.2° below the longer 1895–2019 March average. It was close to the long-term (1981–2010) average February temperatures in Washington, DC, Paducah, KY, and Bristol, TN.

February precipitation (rain and melted snow) came in very close to the 1981–2010 average at 2.82”. This is just 0.02” above average and ranks as the 62nd driest (and 65th wettest) of the past 126 years. Divisional totals ranged from 2.48” (-0.34”, 49th driest) in the north, 2.99” (+0.21”, 60th wettest) in the south, and 3.37” (+0.48”, 51st wettest) at the coast.

There were multiple faces to December weather around the Garden State. Regionally, the north received above-average snowfall, several episodes of freezing rain, and over two weeks of snow cover, particularly at higher elevations. Central and southern areas saw less snow than average and temperatures a little milder than normal compared to up north. There was also a notable difference between the first and second halves of the month, with the first being stormy and the second having just one storm.

Despite a wintry start to the month, the statewide average temperature of 36.3° was 1.1° above the 1981–2010 normal and ranks as the 29th mildest since 1895 (tied with 2016). The north portion of the state averaged 33.1° (+0.4°), the south 38.2° (+1.6°), and the coast 39.4° (+1.7°). Despite a rather dry second half, the 5.56” of rain and melted snowfall averaged across the state was 1.71” above average, ranking as the 19th wettest (tied with 2012). The coast was wettest, averaging 6.09” (+2.33”), followed by the south with 5.60” (+1.81”), and then the north with 5.44” (+1.49”). Snowfall averaged 3.2”, which was 1.6” below average. The north came in with 8.0”, or 1.4” more than average, while the central area had 3.4” (-2.0”) and the south 0.5” (-3.1”).
