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.

October temperatures averaged 54.1° across NJ. This is 1.3° below the 1991–2020 normal and was the coolest October since 2009. It was the 57th coolest (tied with 4 other years) of the 128 since 1895. The average high was 64.5° which is 1.3° below normal and is the 48th coolest (tied with 3 years). The average low of 43.6° is 1.3° below normal and ranks 65th coolest (tied with 4 years). Northern NJ averaged 52.1° (-1.2°, 59th coolest [tied with 2 years]), southern 55.1° (-1.4°, 56th coolest [tied with 3 years]), and coastal 56.6° (-1.0°, 70th coolest [tied with 1 year]).

Rainfall was abundant, averaging 6.45” statewide. This is 2.26” above normal and ranks 10th wettest on record. It was the wettest since the record October 2005. Ten different decades are found in the top 15 years. The north averaged 5.88” (+1.43”, 21st wettest), south 6.75” (+2.72”, 6th wettest), and coast 7.53” (+3.44”, 3rd wettest). Coastal Monmouth, Ocean, and Atlantic counties were wettest, coming in at two to three times normal totals. While coming in close to normal, the driest areas were in the north central, far southern, and southwest regions.

NJ monthly average temperature normals for the 1981–2010 and 1991–2020 periods.

Human-induced climate change is no longer an abstract concept or a threat to be faced in the future. It is currently changing the workings of Earth’s atmosphere and causing extremes in weather events (Arguez et al. 2012). It is the warming of the environment from human activity that is indicated through variables such as temperature, precipitation, and sea level. This global phenomenon influences regional climates. In particular, New Jersey has been one of the fastest warming states throughout the country (New Jersey Department of Environmental Protection 2020) and observing how is...

Following a hot and dry summer, the questions of the day in September were when the temperature would begin to cool and would more abundant rainfall arrive. Signs of a rainfall resurgence were mixed, with drought conditions diminishing in spots but worsening in others. The temperature answer came in almost a flash on the 22nd (the first day of astronomical fall!) when a powerful cold front sent the thermometer quickly downward with an early-fall-like pattern arriving and remaining through month’s end. September temperatures averaged 67.8° across NJ. This is 0.9° above the 1991–2020 normal...

Much like this past July, August was a hotter and drier month than normal. Despite a June with rather close-to-normal numbers, the two most recent months brought the summer temperature and precipitation to top-10 levels for hot and dry conditions. More on summer ’22 later in this report, but first to discuss is a record hot and quite dry August. The August average temperature of 77.4° was 3.8° above the 1991–2020 normal, ranking as the hottest on record. Eight of the ten warmest Augusts since 1895 have occurred since 2001. The average maximum of 88.5° was 4.7° above normal, the hottest on...

Record Heat: July 2020 Recap

August 8, 2020 - 7:03pm -- Dave Robinson

Upper Township hail on July 1st

July 2020 was the hottest month on record for the Garden State since records commenced in 1895. The statewide average temperature of 78.8° was 4.2° above the 1981–2010 normal. This reading surpasses by 0.4° the previous record held jointly by 1955, 1999, and 2011. The next ten warmest months have occurred in July, with the warmest August averaging 76.8° in 2016, which is tied with July 1994 as the 11th warmest month on record. The average 88.9° maximum this past July was 5th warmest, the warmest occurring in 1999. The average minimum of 68.8° ranked second, trailing just 2013. The southern and coastal climate divisions had their warmest month on record while the northern division ranked second.

The statewide average precipitation this July was 6.79”. This is 2.22” above the 1981–2010 normal and ranks as the 15th wettest July on record. Looking at the state in quarters from north to south, the northernmost was driest, particularly the northwest. Next came a wet sector, followed by a more average one, with the southernmost quarter the wettest. Few locations received less than 4 inches, while scattered totals of more than 10 inches were found in the two wettest quarters.

Summer Arrives: June Recap (with a brief look at the first half of 2020)

Tree blown over from June 3rd derecho

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.

Endless Spring: May and Spring 2020 Recaps

June 7, 2020 - 6:34pm -- Dave Robinson

In recent years, many a comment has been heard that New Jersey just does not have a spring season any more. We go right from winter to summer weather, people say. The same cannot be said for spring 2020. A seasonal summary follows at the end of this report and the individual March and April reports can be found on the state climate office website. To begin here, the talk will be of May, a month that produced both less rain and cooler temperatures than normal and included an unusual appearance of snow.

The statewide average temperature of 58.9° was 1.7° below the 1981–2010 normal. This ranked as the 40th coolest May since records commenced in 1895. April and May marked the first time since December 2017–January 2018 that consecutive months had below-average temperatures. Statewide, May precipitation averaged 2.50”. This was 1.49” below normal and ranked as the 29th driest on record.

Blown Away: April 2020 Recap

Gas station canopy collapse

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.

2019/20 season snowfall map

As we gradually transition into warmer spring temperatures, it’s a good time to recap what was a disappointing season for snow lovers, along with snowplow drivers, auto body repair people, and others who profit from snowy winters.

Seasonal snow totaled 4.7” averaged across the state. This is 19.2” below the 1981–2010 average and, looking back from the 1896/96 to 2018/19 snow seasons, is 21.4” below average. This ranks as the third least-snowy winter snow season, only behind the winters of 1972/73 and 1918/19.

Spring Ahead: March 2020 Recap

April 7, 2020 - 11:40am -- Dave Robinson

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.

Exploring NJWxNet Solar Radiation Observations

March 20, 2020 - 11:52am -- Rohan Jain

Serving a wealth of potential user needs, solar radiation is one of the many variables observed at stations within the Rutgers NJ Weather Network (NJWxNet). Dating back as far as 2004, the original solar network of a half dozen stations has grown to the current 46. The solar instruments record incoming radiative fluxes in the 0.36 to 1.12 micron range. A myriad of products stem from observations, initially gathered once each hour and, since mid-2012, every five minutes. These include radiation maximums, averages, minimums (W/m²), and totals (kJ/m²), at five minute, hourly, and daily time scales.

Solar data gathered at NJWxNet sites help promote an understanding of the relationship between solar radiation and terrestrial systems involving the heating of the surface and atmosphere, plant growth, human health, and energy generation. Atmospheric conditions influence the magnitude of irradiance reaching the surface, with variables such as cloud cover, humidity, and aerosols (minute natural and human-generated liquid or solid particles) influencing incoming radiation. Prior to the advent of the NJWxNet, solar radiation observations across the Garden State were few in number and most often not of a continuous long-term nature. This was the case elsewhere in the US prior to the recent establishment of mesonets, such as the NJWxNet, in many states.

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.

Where is Winter?: January 2020 Recap

February 4, 2020 - 2:01pm -- Dave Robinson

The new decade got off on a rather unwintry note, with January temperatures well above average, snow rarely falling, and just one significant storm that brought only rain. The statewide average temperature of 37.3° was 6.6° above the 1981–2010 mean. This ranks as the 8th mildest January (tied with 1933) since records commenced in 1895. Anomalies and rankings were quite similar across the state. January 2020 was milder than December 2019 by 1.0°. The last time this climatological flip occurred was in December 2005/January 2006. Most notably, January 11th and 12th saw record daily temperatures in the upper 60°s to as high as 70°.

Precipitation fell mostly in the form of rain and mainly on the 25th. The monthly average across NJ was 2.38”. This is 1.02” below the mean and ranks as the 26th driest. The north was 1.27” below average, the south -0.84”, and the coast -1.12”, with all divisional totals between 2.14”–2.55”.

Winter Arrives Up North, Not So Much in the South, and Another Mild and Wet Year: December and 2019 Annual Recaps, Including Top 10 Events

January 7, 2020 - 5:22pm -- Dave Robinson

Freezing rain photo

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”).
