These are the hottest days ever on record for North Jersey

If any North Jersey residents needed a reminder that summer is here, a brief trip outside for much of June certainly would have done the trick.

But while the temperatures may feel hotter than ever, historical data shows the region is still well shy of setting any records in the near future.

Hottest days ever in NJ

The all-time high temperature in New Jersey is 110 degrees, recorded on July 10, 1936 at a weather station near Old Bridge, according to Bob Ziff of the North Jersey Weather Observers. Bergenfield hit its record of 105 degrees on July 6, 2010, the same day as Cedar Grove's high benchmark of 104.

Temperatures in the triple digits are rare in North Jersey but not completely unheard of. Bergenfield, for example, has recorded 20 days with a high of at least 100 degrees over the past four decades since the data became available, Ziff said.

Below is a list of every 100-degree day on record at North Jersey weather stations, according to Ziff.

Bergenfield (since 1983)

105 degrees (one day): July 6, 2010

104 degrees (two days): July 22, 2011; Aug. 9, 2001

103 degrees (two days): July 18, 2012; July 7, 2010

102 degrees (three days): Aug. 13, 2005; July 17, 1999; July 5, 1999

101 degrees (four days): July 21, 2011; June 10, 2008; Aug. 12, 2006; July 15, 1995

100 degrees (eight days): Sept. 1, 2010; July 4, 2010; June 9, 2008; July 10, 2007; Aug. 1, 2006; Aug. 3, 2005; July 26, 2005; Aug. 8, 2001.

Cedar Grove

104 degrees (one day): July 6, 2010

Paterson

106 degrees (one day): Sept. 3, 1953

105 degrees (one day): July 5, 1949

104 degrees (one day): Aug. 7, 1918

103 degrees (one day): June 22, 1953

101 degrees (one day): May 31, 1895

Bergenfield recorded a high of 93 degrees Wednesday, three below the June 26 record of 96 set in 2003, Ziff said. That mark is also the high for June 27 and 28, set in 2007 and 2021, respectively.

The benchmarks for Sussex are slightly higher: 98 degrees for June 26, set in 1952; 97 for the 27th, set in 1921; and back to 98 for the 28th, set in 1966.

Rounding out the month, the June 29 record is 98 degrees in both locations, Ziff said. Bergenfield reached 99 degrees on June 30, 2021, while Sussex set the record of 97 for that date in 1931.

Start of summer

Summer officially began last Thursday, although the warm weather had already arrived in the area a couple days earlier. The heat wave continued into that weekend, when the National Weather Service issued a heat advisory Sunday for parts of North Jersey as temperatures climbed into the 90s and the heat index broke 100 in some places.

But Ziff said he was "not expecting any broken records" in North Jersey by the end of June. In fact, he noted, the data shows Bergenfield is close to its average rate of high temperatures for spring into summer.

The borough normally has two days with a high of at least 90 degrees in May and five in June, Ziff said. This year saw no such days in May before picking up the pace to eight so far this month.

"I'm not really sure why people are so excited about this," Ziff said of the recent heat wave. He suggested it may be because of the conditions last June, when the temperature in Bergenfield was 1.7 degrees under the average on the way to its first summer below normal in many years.
