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.

July 2018 had a classic variety of summer weather. There was: 1) an ongoing heatwave to begin the month; 2) dry conditions for the most part in the first half of the month; 3) some warm, exceedingly humid conditions with widespread, at times heavy, showers the second half of the month (courtesy of the subtropics); and 4) some “top 10” sunny dry days following several cold front passages (thank you Canada). The average statewide July temperature was 76.4°. This is 1.8° above the 1981–2010 average and ranks as the 13th warmest July in 124 years of records (2.6° above the full period of...

After an ample share of ups and downs throughout the past spring, the weather in June became rather typical for the start of summer. It was drier than average in the north and wetter than usual in the south, with the temperature close to the long-term mean. Fortunately, New Jersey entered the heart of summer with reservoirs full. However, with the onset of an apparent extended period of heat late in the month, it is certainly prudent to conserve water wisely. The June average statewide temperature of 69.8° equaled the 1981–2010 mean, but is 1.0° above the 1895–present average. This tied...

After April timidly transitioned into milder weather, May was plenty bold in the thermal department, on multiple occasions behaving more like summer than late spring. Most NJ residents did not seem to mind the warmth; rather, from the second week onward, it was the frequent episodes of rain, often targeting weekends, which raised the level of crankiness among many! Statewide, this was the 5th warmest May since records commenced in 1895. The 65.0° average was 4.5° above the 1981–2010 mean. Five of the ten warmest Mays have occurred since 2004. In most locations, rain fell on at least half of...

Here we are again in a weak La Niña situation as the heart of the 2017/18 winter approaches. Thus far...

Plenty Dry with Backwards Warmth: September 2017 Summary

October 5, 2017 - 4:40pm -- Dave Robinson

Waves photo

While remarkable deadly and destructive hurricanes pummeled portions of the Caribbean and southern states, September weather conditions in the Garden State were generally quiet. The most notable exceptions were the dangerous rip currents at the Jersey shore associated with the latter stages of Hurricanes Irma and Jose, which resulted in several drowning deaths and numerous water rescues. Minor to some moderate back-bay flooding and beach erosion accompanied the tumultuous surf, particularly between the 18th–21st. Otherwise, little more than some clouds and light rain reached NJ from these storms, while earlier some remnant energy and moisture from Hurricane Harvey brought one of the month’s few notable rain episodes. Dry conditions prevailed through much of the September, especially the second half. As a result, statewide precipitation averaged just 2.23”. This is 1.82” below the 1981–2010 average and was the 28th driest September since 1895.

While the first half of the month had an average temperature of about a degree below normal, September finished on a warm note. Some locations experienced three consecutive days with maximums of 90° or higher from the 23rd–25th. This backwards turn to warmth while the calendar suggested there should be a decline in temperature resulted in the month averaging 2.6° above the long-term mark. The 68.4° average made this the 10th warmest September on record. The last three Septembers and six since 2005 all fall into the top 10.

It’s Not Easy Staying Green: August and Summer 2017 Summaries

September 7, 2017 - 4:49pm -- Dave Robinson

Tomatoes

Despite July and August typically being the wettest months of the year in New Jersey, their warmth usually results in evaporation rates exceeding rainfall. Thus, when heat ensues and rain is light for a few weeks—not uncommon in a Jersey summer—lawns, gardens, and fields require considerable irrigation to avoid wilting or browning. Such was not the case this past August and earlier in the summer, as rain was ample and quite timely in most areas and hot temperatures did not prevail for extended periods. More will be reported for the summer as a whole later in this report. For August in particular, the average of 5.06” of rain that fell across NJ was 0.96” above the 1981–2010 average. It ranked as the 41st wettest August since 1895 and the wettest since record wet conditions in 2011.

The average statewide August temperature of 71.7° was 1.3° cooler than the 1981–2010 average (tied with 1926, 1952, and 1985). It was 5.1° cooler than last year’s record warm August. Since 1895, there have been 57 cooler Augusts and 62 that were warmer, which reflects the fact that this year was only 0.2° cooler than the 1895–2017 average. Yes, Augusts have generally warmed in recent decades.

Rainfall Corridors: July 2017 Summary

August 4, 2017 - 4:20pm -- Dave Robinson

Valley fog photo

July 2017 proved to be an active month of weather throughout the Garden State. Time and time again, storms traversed the state, often depositing the heaviest rainfall in 30–40 mile west-to-east “corridors,” while elsewhere totals were much lighter. Such is the nature of showery summer rainfall, although in one case, the swath of heavy rainfall was associated with an out-of-season coastal storm. When all was said and done, rainfall occurred frequently enough to leave most locations with average to well above average monthly totals. The statewide average July rainfall was 6.33”. This is 1.76” above the 1981–2010 average and ranks as the 19th wettest July of the past 123 years. Last year with 6.97” (ranking 13th) and 2004 with 7.51” (ranking 8th) were the most recent Julys to be wetter than this year. The statewide average temperature of 75.5° was 0.9° above average. This ranks as the 22nd warmest July on record. There have been nine warmer Julys since 2002, including last year at 77.1° (ranking 7th).

A Potpourri of Weather: June 2017 Summary and Mid-Year Recap

July 5, 2017 - 5:19pm -- Dave Robinson

Occasionally there are months that defy a “directional” theme when it comes to the weather and climate conditions experienced across the Garden State. In other words, conditions didn’t lean markedly toward, for example, wet or dry, cold or warm, or calm or stormy. June 2017 was one of those “potpourri” months. There were thunderstorms with drenching rain and even two tornadoes occurred, yet there were stretches of comfortable, dry weather. There was a three-day heat wave, with the temperature going as high as 97°, and some cool nights, with 35° being the coldest observed temperature in the state. When the precipitation was added up, the statewide average came out to 3.34”, which was 0.67” below the 1981–2010 mean of 4.01” and ranks as the 54th driest June of the past 123 years. The statewide average temperature of 70.5° was 0.7° above average. This ranks as the 27th mildest June on record.

Talk of Drought Evaporates: May and Spring 2017 Recaps

June 5, 2017 - 4:19pm -- Dave Robinson

Bayonne street flooding

It is always comforting to enter the water demand season, namely summer, with a bit of a hydrological cushion. Such is the case this year across NJ, thanks to ample rain and some late-season snow in recent months. This timely precipitation has eliminated drought concerns that stemmed from drier-than-normal intervals during 2016. As a result of the precipitation deficits, ground water, streamflow, and reservoirs all dropped to precarious levels, thus the issuance last fall of a drought warning by the NJ Department of Environmental Protection over northern NJ and a drought watch in some southern counties. Aside from two reservoirs in west central NJ remaining below average, at the moment all other hydrological signs are positive. However, no one should let their guard down and fail to appreciate the finite nature of our fresh water resources, and how quickly a period of abundance can lapse again into drought.

More will be noted regarding spring (March–May) conditions later in this report. First taking a look at May, New Jersey experienced its 9th wettest on record, with observations extending back to 1895. The statewide average rainfall of 6.62” was 2.63” above the 1981–2010 average and the wettest May since 1990. Frequent clouds and rain resulted in many chilly days, however, a mid-month heat wave was impactful enough such that the average statewide temperature of 59.8° was only 0.7° below the 1981–2010 average. It was the 61st coolest May of the past 123 years, with none cooler since 2008.

Record Warmth Returns: April 2017 Recap

May 5, 2017 - 2:19pm -- Dave Robinson

Following a March with the first substantially below-average monthly temperature anomaly in NJ in over a year, April brought a return to record warmth last seen in February. With a statewide average of 56.0°, the month was 5.1° above the 1981–2010 mean. This ranked as the warmest April since statewide records commenced in 1895. Five of the top 10 and nine of the top 20 mildest Aprils of the past 123 years have occurred since 2002. With the warmth of January, February, and April hardly balanced by the colder March, this year is off to the 4th warmest start on record. Only January–April averages in 2012, 1998, and 2002 were higher, and five of the eight mildest such intervals in the past 123 years have been since 2002. The 12-month period from May 2016 through April 2017 was the third warmest on record at 55.5°. It was only surpassed by May 2011–April 2012 (56.5°) and 2015–2016 (56.2°). Twelve of the 15 warmest such intervals of the past 123 years have occurred since 1999, the others being in 1931–1932 (#10), 1990–1991 (#11), and 1991–1992 (#14).

Long Winded: March 2017 Recap

April 4, 2017 - 4:15pm -- Dave Robinson

Damaged Magnolia

With the Northern Hemisphere atmosphere transitioning from winter to spring, March can be a month of frequently-changing weather with pronounced pressure gradients, thus punctuated by windy conditions. This past March was no exception, and in fact, a windier month would be difficult to find. Winds gusted to 50 mph or greater at one or more NJWxNet station on 11 days and between 40–49 mph on four other days. At most locations, the warmest daily average temperature of the month was, of all things, on March 1st, while the first 80° day of the year was on the 25th. In between those warm spells was the largest snowstorm of the year in central and northern locations and two weeks of some of the coldest weather of the winter. Finally, March went out like a lion, with a statewide soaking rainstorm on the 31st.

The statewide monthly average temperature of 38.9° was 1.9° below the 1981–2010 average. This ranks as the 61st coldest of the past 123 Marches. It was the first month with a below-average temperature since last May, which was only 0.3° below average and last April with a 0.1° negative anomaly. While not exceptionally cold, due to the record warm February average of 40.1°, this was only the third time on record when March was colder than the previous February. This occurred previously in 1984 and 1960. The 1960 occurrence was mainly due to March being the second coldest on record, while in 1984, February was 9th mildest and March 10th coolest. On average, March is 7.3° warmer than February. While the cold of March damaged blossoms of some prematurely-blooming trees and flowers, vegetation was not far enough along to result in significant problems.

March in February, & Another Mild Season: February and Winter 2016-2017 Recap

March 6, 2017 - 4:26pm -- Dave Robinson

Crocuses photo

On many an afternoon this past February, one had to be reminded that, according to the calendar, we were in the midst of a winter month. While there was a modest snowstorm for central and northern areas on the 9th, there were 11 days, including the day prior to the storm, when temperatures equaled or exceeded 60° at one or more New Jersey locations. The average statewide monthly temperature of 40.1° made February 2017 NJ’s mildest since records commenced in 1895. The average was 6.6° above the 1981–2010 mean and 1.0° above the previous record in 1998. In fact, the 2017 average was only 0.7° lower than the mean for March, and would rank as the 54th mildest (69th coolest) March on record. February precipitation (rain and melted snowfall) averaged 1.70”. This was 1.10” below the 30-year mean and ranks as the 11th driest on record. Only the storm on the 9th delivered more than an inch of rain or melted snow to some observing stations around the state.

The Weather Would Not Sit Still: January 2017 Recap

February 6, 2017 - 10:51pm -- Dave Robinson

Rough surf photo

A progressive weather pattern dating back to last fall continued to hold serve across the eastern US in January. This resulted in temperatures swinging between mild and cold levels and unsettled weather systems moving through often enough to bring precipitation levels close to average but, with one notable exception, not staying around too long to wreak havoc. Overall, it was a mild month, with a statewide average temperature of 36.2°, which is 5.5° above the 1981–2010 mean. This ranks as the 12th mildest January since 1895. It is interesting to note that while 10 of New Jersey’s warmest 15 years have occurred since 2000 and 14 of 15 since 1990, Januaries have not as often kicked off these warm years as much as one might imagine. Only 5 of the 15 mildest Januaries over the 123 year record have occurred since 2000 and just 8 of the 15 mildest since 1990.

A Rather Quiet End to the Year: December 2016 Recap and Annual Summary, including the Top 10 Events of 2016

January 4, 2017 - 3:40pm -- Dave Robinson

Snow photo

The atmosphere was in a progressive mode throughout December, which explains why no particular weather feature lingered in NJ or elsewhere across North America for too long. The seemingly day-to-day changes resulted in the statewide mean temperature of 36.4° being just 1.2° above the 1981–2010 normal. This ranks as the 28th mildest December since statewide records commenced in 1895, a far cry from last year’s record mild conditions. Despite there being seven precipitation events, one of which was mainly a carry over from November 30th, the rapid movement of these systems meant that none deposited prodigious totals in NJ. Thus 3.37” fell, which is 0.48” below average. This ranks as the 55th driest December. Monthly statewide snowfall averaged 2.0”. This is 2.1” below the 1981–2010 average and ranks 45th least snowy. The northern seven counties averaged 5.5”, the central six counties averaged 1.8”, and the eight southern counties 0.2”, all below average.
