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.

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...

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...

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...

A Dreary Month, and Shades of Years Past: December and 2014 Annual Summary

January 5, 2015 - 9:58pm -- Dave Robinson

Coastal Flooding from Dec 9 Nor'easter

Clouds prevailed in this darkest month of the year, making for some rather persistent dreary conditions. Until the last week of the month there were only two days (the 4th and 7th) where the sun outperformed the clouds across NJ. At least the year ended on a bright note, with lots of sun during five of the last six days. With the clouds came a fair amount of precipitation, and given milder-than-normal conditions, the vast majority was in the form of rain. Statewide precipitation averaged 4.79". This is 0.88" above the 1981–2010 mean and ranks as the 27th wettest December since 1895. The mean temperature of 38.9° was 3.3° above average and ranked as the 15th warmest on record. Snowfall averaged 0.6", some 3.5" below average and ranked as the 19th least snowy December. A strong nor'easter brought strong winds, multiple inches of rain, minor to moderate coastal flooding, and beach erosion on the 9th.

ONJSC's Top 10 NJ Weather and Climate Events of 2014

Listed below is the Office of the NJ State Climatologist's ranking of the top 10 weather and climate events of 2014. More about each event can be found in the monthly narratives posted on njclimate.org. You might be tempted to rearrange the rankings, particularly as some of the events may have affected you more than others higher on the list. That's the enjoyment (and frustration!) of lists. This was the second consecutive year that was not too eventful for NJ weather and climate (goodness, we remain stunned by 2011 and 2012). Of course there is still plenty to talk about.

Winter Weather Trends: El Niño in New Jersey

December 19, 2014 - 4:41pm -- Jack McCarty

Global Sea Surface Temperature Anomalies

As we have mentioned in our past evaluations of the El Niño’s significance in the summer and fall, we are back again to analyze the wintertime impacts of a developing El Niño on New Jersey weather. An El Niño occurs when warmer-than-average waters exist in the central and eastern Pacific Ocean, specifically near the equatorial latitudes. This warming is due to a weakening of winds moving to the west, which typically transport warmer waters to the western Pacific, permitting cooler water to upwell to the surface in the east. When these winds are weaker or if they reverse direction, warm water stays in the east. The warmer sea surface temperatures in the east and the altered atmospheric flow pattern create a new dynamic between the ocean and atmosphere. The newly formed interaction sets up distinct and repetitive weather patterns across the world. No two El Niño events are alike; they vary depending on the magnitude and location of where the largest temperature anomalies are found. However, each one tends to alter weather patterns outside the overall norm.

A Cool Damp Month, and All Things Considered, a Rather Average Season: November and Fall 2014 Recap

December 7, 2014 - 7:32pm -- Dave Robinson

Wantage snow Nov 27

While cooler conditions took some time to arrive in New Jersey this fall, once here they locked in for the most part, as the November average temperature of 41.9° was 3.7° below the 1981-2010 average. This ranks as the 24th coolest November of the past 120 years. November precipitation (rain and melted snow) averaged 4.58" across the state. This is 0.94" above average and ranks as 31st wettest. On two occasions measurable snow was reported in northern and central areas, with these regions, respectively, picking up 4.6" and 1.9" on average for the month, with over a foot accumulating at higher elevations. Despite no snow accumulating in the south, the statewide average was 1.7", which is 1.3" above average. It is only the second November to average above an inch since 1995, the other in 2012. A Thanksgiving eve storm delivered a white Thanksgiving to central and northern counties.

Mild With Some Beneficial Rain: October 2014 Recap

November 3, 2014 - 4:57pm -- Dave Robinson

Waterspout photo

The tenth month of 2014 bucked the recent tendency toward dry conditions in northern New Jersey and proved to be the warmest month compared to normal since October 2013. Statewide, the October average temperature of 57.0° was 2.2° above the 1981-2010 average. This ranks as the 23rd warmest (tied with 1955) in 120 years (since records began in 1895). The average precipitation across NJ was 3.78". This is 0.15" below the mean and ranks as the 51st wettest October. Rainfall was above average in what have been some of the driest northern counties since mid summer. Still, from Mercer and Middlesex counties northward, precipitation has only been 50-75% of normal the past three months. Thus this area is still considered "abnormally dry" on the US Drought Monitor map.

El Niño Potential: Fall Impacts

October 15, 2014 - 10:12pm -- Jack McCarty

Sea Surface Temperature Anomalies

Early this past summer, we reported on the potential impacts of a developing El Niño event in the tropical Pacific on summertime weather in New Jersey. While El Niños can impact the weather worldwide, we found that New Jersey's weather doesn't fluctuate with an El Niño event. This year's summer (June-August) proved to be rather comfortable, with the statewide average temperature 0.8° below the 1981-2010 average , and precipitation 0.26” above the 1981-2010 average. These mild conditions replicated what we expect out of an El Niño summer. Now we’re back to tell you the story for the fall.

Increasingly Dry in the North: September 2014 Recap

October 6, 2014 - 3:04pm -- Dave Robinson

Dry grass

Combined with below-average precipitation in August, the northern half of New Jersey has become quite dry. Conversely, rainfall has been more common in the south, thus despite a drier-than-average September, the two-month total is slightly above average. Looking first at September, statewide precipitation averaged 2.82". This is 1.25" below the 1981-2010 average and ranks as the 46th driest September since 1895. From Hunterdon, Somerset, and Union counties northward, only 1.49" fell, which is 3.00" below average and ranks as 7th driest. The southern counties averaged 3.47", which is 0.40" below average and ranks as 56th wettest.

The summertime in New Jersey is characterized by warm temperatures that give some relief from cold and dreary wintertime conditions. However, amongst pleasant summer days, the atmosphere can align in a way that makes the heat on other days rather unbearable — something that we commonly refer to as a heat wave. Heat waves have a large impact on public health, utilities, infrastructure and more, which is why we often hear the media discussing heat waves across the nation. While heat waves may call for a day at the beach, they're also a cause for public concern.

Comfort Reigns: August and Summer of 2014 Recaps

September 3, 2014 - 5:50pm -- Dave Robinson

Surf photo

A month ago, many NJ residents felt July was quite cool, while in fact it was just 0.4° below the 1981-2010 mean. Such was not the case in August, which truly was on the cool side. The statewide average temperature of 71.0° was 2.4° below average. It ranks as the 32nd coolest since 1895. Even when compared to the 1895-present mean, the month was 1.5° below average. Days with a maximum temperature of 90° or greater were hard to find, certainly a characteristic of the summer of 2014, which will be discussed later in this narrative.

Precipitation varied widely across the Garden State in August, rather typical of a summer month in these parts. Individual station totals ranged from 12.33” in Lacey Township (Ocean County) to 1.01” in Hillsborough (Somerset). When monthly totals from several dozen long-term stations were averaged together, the statewide precipitation was 4.39”. This is 0.18” above the 1981-2010 mean (0.26” below the 1895-present mean) and ranks as the 53rd wettest of the past 120 Augusts. It must be noted that the heavy rain that fell after 8 AM on the 31st is not accounted for in most August station totals. For the monthly state average, only several stations that observe at midnight have their full August 31st totals included, while monthly totals at most other National Weather Service Cooperative stations only run through the morning of the 31st. For more on this observing practice, see the April 2014 report.

New Jersey Hurricane Hunting: A brief recap of a small state’s big hurricane history

August 21, 2014 - 1:35pm -- Tom Karmel

Doria flooding photo

With more than a third of the 2014 Atlantic hurricane season behind us, many may assume this season has been quiet. However, the two hurricanes already named mark the first time since 1992 when the first two named storms have reached hurricane strength and the first time there have been two hurricanes by this date since 2008. With the peak of the tropical season yet to come, the question is whether the heart of the season will be active or quiet. The National Weather Service’s Climate Prediction Center recently updated their seasonal forecast, projecting only a 5% chance of an active season and 70% chance of a less than normal one. Still, it only takes one storm to seriously impact NJ, so we can never let our guard down. With this in mind, here is a brief history of memorable tropical cyclones affecting New Jersey and a summary of the frequency of storms through the hurricane season.
