2019’s ranking among hottest years in New Jersey since 1895

Dr. David A. Robinson and team at the Office of the New Jersey State Climatologist have been reviewing the data for 2019. One of their conclusions: 2019 was the 10th hottest in New Jersey since 1895. With a statewide average temperature of 54.3 degrees Fahrenheit, that was 1.4 degrees above the 1981-2010 average and tied with 2002 in 10th spot. Last year also gave us our fifth warmest summer. The climatologists point out that 14 of the 20 warmest years of the past 125 have occurred this century and 18 since 1990. They list 2012 as hottest year ever in the Garden State, with an annual average temperature of 55.9 degrees. After that came 1998 (55.2 degrees), 2006 and 2016 in joint third place (55 degrees), followed by 2011 (54.9 degrees), 2010 (54.7 degrees), 2017 (54.6 degrees), 1990 (54.5 degrees) and 1991 (54.4 degrees).

Observations were drawn mainly from National Weather Service Cooperative Observing Program stations, Rutgers NJ Weather Network stations, and NJ Community Collaborative Rain, Hail and Snow Network locations.
