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.

Lambs and Lions: March 2019 Summary

April 5, 2019 - 5:07pm -- Dave Robinson

Snow photo

Much like last month, March 2019 had a wide variety of weather conditions across the Garden State. The month came in like a lion, with a week of wintry weather, which was particularly snowy in northern and central regions. More snow fell than in any other month this season and the temperature fell below zero in one location and down to single digits at a number of others. The remainder of the month was often lamb-like, including four days with high temperatures exceeding 70° at many locations and six in the 60°s. Several inch-plus rain events occurred, along with the first lightning-filled squall line of the year, which, in some locations, included hail and strong winds.

The statewide monthly temperature averaged 39.7°. This is 1.1° below the 1981–2010 average and is the 58th mildest (66th coolest) since 1895. The statewide average rain and melted snow totaled 3.91”. This is 0.20” below the 1981–2010 average. It was the 61st wettest (65th driest) March since 1895.

Statewide snowfall averaged 6.3”. This was 1.9” above average. Northern counties averaged 13.0” (6.7” above average), the central region 8.6” (+3.5”), and south 1.6” (-1.5”). As a preview of the seasonal snow summary in next month’s report, statewide snowfall through March is 20.5”, 5.0” below average. Barring the unlikely case of April snowfall exceeding any other month of the season, this will mark the first time since records began in 1895 that March was NJ’s snowiest month of the season for three consecutive snow seasons (October–April).

A Little Bit of This and a Little Bit of That: February and Winter 2019 Recaps

March 5, 2019 - 8:23pm -- Dave Robinson

Tree felled by wind

The second month of 2019 across New Jersey was not one that will leave an indelible mark in the memory bank. Unlike some of the wild conditions that afflicted many other parts of the nation, NJ precipitation events were only minor to moderate, and there was nothing in the way of stream and river flooding. On several occasions, cold and warmth came and went rather quickly. There were no coastal storms, thus no significant tidal flooding or beach erosion. While there was one notable wind event, overall, rather calm conditions prevailed.

The statewide average precipitation (rain and melted snow) was 3.27”. This is 0.47” above the 1981–2010 average and ranks as the 47th wettest February since 1895. The statewide average temperature of 34.8° was 1.3° above average, and ranks as the 26th mildest February of the past 125 years.

Ambivalence: January 2019 Summary

February 7, 2019 - 5:19pm -- Dave Robinson

Marcal paper plan fire aftermath

If there was one thing the weather of January did not possess, it was a consistent identity. Though one might say that conditions during the first month of 2019 were consistently inconsistent, oftentimes with rapid transitions. Yet when all was said and done, conditions did not average too much from the long term norm. Statewide, the average temperature of 31.9° was just 1.2° above the 1981–2010 mean and ranks as the 35th mildest since 1895. This included two days where the thermometer topped 60° in a few locations and four days with some places falling below zero. Rain and melted snow totaled 4.39” on average, which was 0.99” above average. This ranks as the 28th wettest January on record. Four events brought more than an inch of liquid to some locations, yet there was a two-week stretch without such an abundant total.

Snowfall averaged 3.8”, which is 3.4” below normal and ranked as the 44th least snowy January dating back to 1895. There was one somewhat notable snow event in the south and two in the northwest, though there were no “blockbuster” winter storms. Central and northeastern areas were almost shut out for the month in the snow department, and for that matter, mostly devoid of snow since the unseasonable event of November 15. For instance, Newark (Essex County) received just 0.9” and New Brunswick (Middlesex) 0.8”, the least in January for each station since 2008. For the month, snowfall over the north division averaged 5.8” (-3.5”), central 1.8” (-6.1”), and south 3.8” (-2.0”). For the season thus far, NJ has averaged 8.9” (-3.9”), the north division 13.7” (-3.5”), central 6.6” (-7.7”), and south 7.5” (-2.5”).

A Fitting Finale: December 2018 Recap and Annual Summary, including the Top 10 Events of 2018

January 7, 2019 - 1:58pm -- Dave Robinson

Rainy street

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.

December precipitation totaled 5.38”. This is 1.53” above the 1981–2010 average and ranks as the 20th wettest (tied with 2007). Snowfall averaged 1.0”, which is 3.9” below average and the 31st least snowy December since 1895. The only notable snowfall was across a swath of south Jersey on the 5th, leading to a south Jersey monthly average of 1.7”. This is 1.9” below average and ranks as the 55th least snowy December. Northern counties averaged 0.6” for the month, some 6.0” below average and ranking 19th least snowy. Central counties came in without any measurable snowfall. This is 5.5” below average and joins ten other Decembers of the past 124 years without measurable snow, four of which have been this century (2001, 2006, 2011, and 2015).

The average statewide temperature was 37.5°. This is 2.3° above the 1981–2010 average and ranks as the 18th mildest December of the past 124 years (tied with 1972 and 1991).

Winter Arrives Early, Record Wet Fall: November 2018 and Fall 2018 Recaps

December 5, 2018 - 5:11pm -- Dave Robinson

Snow-covered highway

November weather packed quite a punch, putting an exclamation point on what will go into the book as the wettest Fall (September–November) on record (since 1895). With seven storms that each deposited an inch or more of rain (or melted snow) at numerous locations, this was the second wettest November. The statewide average of 8.77” was 5.16” above the 1981–2010 average. The record will remain 9.01” in 1972.

One of the largest early-season snowstorms on record delivered significant impacts to all but southeastern NJ on the 15th. This event alone resulted one of the snowiest Novembers on record. Statewide, the monthly snowfall was 4.1”, which is 3.3” above average and ranks as the 6th snowiest since 1895 and the snowiest since 1989. With 7.4” in the north (Sussex, Passaic, Bergen, Warren, Morris, Essex, and Hudson counties), it was the snowiest November since 1938 and 3rd most on record. Central NJ (Hunterdon, Somerset, Union, Middlesex, Mercer, and Monmouth counties) received 4.8” (+3.9”), the 5th snowiest on record and most since 2012. The south (Burlington, Ocean, Camden, Gloucester, Atlantic, Salem, Cumberland, and Cape May counties) averaged 2.0” (+1.4”), the 10th snowiest and most since 2012.

Growing Season Is Over for the Entire State

November 12, 2018 - 12:40pm -- Dave Robinson

With today’s (11/12) minimum temperature at West Cape May (Cape May County) and Lower Alloways Creek Township (Salem) falling to 30° and 32°, respectively, the growing season has ended across the Garden State. The growing season is considered to be the count of days between the last freeze of the spring and the first freeze of the fall (counting neither of those freezing days). This made for a 214 day growing season at West Cape May, while the Lower Alloways Creek Township weather station was just installed in July, thus a seasonal number is unavailable. These first freezes were preceded by a day at the Atlantic City Mariana (Atlantic) and Harvey Cedars (Ocean), which fell to 32° and 31°, respectively, on the 11th. Based on observations from these Rutgers NJ Weather Network stations (the 62 stations upon which the growing season is determined), these two locations had NJ’s longest growing seasons. The Marina saw its last spring freeze on March 22nd, giving it a 233 day season. Harvey Cedars last froze on April 2nd, thus ended with a 222 day season.

Rapid Transition: October 2018 Recap

November 5, 2018 - 7:37pm -- Dave Robinson

Coastal flood photo

October was a tale of two half-months. Summer-like weather prevailed through the 11th, quickly transitioning to fall-like conditions on the 12th. Passage of the first strong cold front of the season was responsible for the change. Moderate to heavy rain accompanied the front in northwest NJ during the daytime hours of the 11th. That evening, and into the morning of the 12th, moisture from the remnants of once major Hurricane Michael ran up against the front and brought heavy rain to south Jersey. This one-two punch was followed on the 17th by the first freezing temperatures of the season at a few locations and a more widespread freeze on the 19th. Generally cool conditions prevailed the remainder of the month. The remnants of yet another major hurricane, Willa, provided energy and moisture to a quick-hitting nor’easter on the morning of the 27th that brought some of the worst coastal flooding since Sandy in 2012. Michael was an Atlantic storm that made landfall in the Florida panhandle, while Willa was an eastern Pacific storm that came ashore on the west coast of Mexico.

First Widespread Freeze of the Season

October 19, 2018 - 10:51am -- Dave Robinson

Oct 19 minimum temperature map

This morning was a frosty one, with many NJWxNet locations across the state seeing their first freezing temperatures of the season. The accompanying map shows that most every location away from coastal and urban environs dipped to the freezing point or lower. Walpack (Sussex County), the traditional cold spot in NJ on calm clear nights, was the coldest spot at 24°. Atlantic City Marina (Atlantic) and Lower Alloways Creek, along the Delaware Bay coast in Salem County, were mildest, with lows of 46°. All other NJWxNet sites were no milder than 42°. One of the more interesting cold readings was the 32° minimum at Jersey City (Hudson). This station is located in Liberty State Park, demonstrating that even parkland within urban regions can get awfully chilly on calm, clear nights. However, it is a bit surprising to see this low, given that the station is quite close to the waters of NY Harbor.

Once Again, Summer is Slow to Depart: September 2018 Recap

October 7, 2018 - 8:18pm -- Dave Robinson

Coastal flood photo

For the fourth consecutive year, summer weather stubbornly hung on well into September across the Garden State. The statewide average temperature of 70.4° was 4.6° above the 1981–2010 mean, and ranks as the third warmest since records commenced in 1895. September 2017, now ranking 11th, sat in the top 10 for just one year before being bumped out by 2018. This September was the fifth consecutive month of above-average temperatures. The past 12 months have seen the 2nd warmest October, 4th warmest May, 1st warmest August (tied with 2016 based on updated figures), and now the 3rd warmest September. The June through September period this year averaged 73.3° (+2.5°), making it the 4th warmest on record. The top 10 such intervals have all occurred since 2005. The August–September average of 73.7° (+4.3°) was the warmest on record, followed by 2005, 2016, 2015, and 2010.

Perhaps what was most interesting about temperatures this past month was the disparity between average maximum and minimum temperature anomalies. The average maximum of 77.7° was 1.4° above average and ranked 27th warmest. However, the average minimum of 63.2° was 7.9° above average and is a whopping 2.2° milder than the previous highest September average minimum. This came about due to the excessive cloud cover and humidity throughout most of the month, which kept the days from getting too warm and, come nighttime, “trapped” much of the heat gained during the day within the lower atmosphere. Thus, unlike the past three warm Septembers (as well as 2013 and 2014), each of which had below-average precipitation, this year was anything but dry. There were frequent rainy episodes, which at times produced localized deluges and resultant flash flooding. The statewide average rainfall of 7.60” is 3.55” above the 1981–2010 average, and is tied with 1960 as the sixth wettest September since 1895. The wettest September on record remains 1999, which averaged 9.50 inches, in no small part due to Tropical Storm Floyd’s rains. Aside from 1999, you have to go back to 1975 to find a September with more rain than this year.

Green Warmth: August and Summer 2018 Recaps

September 5, 2018 - 8:18pm -- Dave Robinson

Flash flood photo

The summer of 2018 concluded on a warm, wet note across the majority of what was a persistently green Garden State throughout the season. The warmth dated back to late June, with frequent humid conditions and abundant showers from mid-July onward. There will be more on the entire summer at the end of this report. First a look at August, with a statewide average temperature of 76.8° coming in 3.8° above the 1981–2010 average. This was the second warmest August since 1895, falling just behind 2016 by 0.1°. Nine of the 13 warmest Augusts during that 124-year interval have occurred since 2001.

Statewide, August precipitation averaged 5.63”. This was 1.53” above the 1981–2010 average and ranked as the 32nd wettest since 1895. It was the wettest August since the record wettest month in 2011. As is often seen in the summer, the majority of the precipitation fell in scattered showers and thunderstorms. This resulted in a wide range of monthly totals around the state, with some serious flash flooding occurring in several locations when moisture-ladened storms parked themselves over an area for multiple hours. Where storms missed time and time again, rainfall totals were below average. The northern NJ climate division (Hunterdon, Somerset, and Union counties northward) saw their 10th wettest August on record, with an average of 8.28” falling. This is 4.17” above average. Since 1990, only August 2011 was wetter in this division.
