Spring Arrives and Remains: April 2015 Recap

Dr. David A. Robinson
New Jersey State Climatologist
May 4, 2015

Complaints are often brought to the Office of the State Climatologist that in recent years the weather in New Jersey has quickly transitioned from winter to summer, thus leaving little time for spring weather. Of course perceptions can be deceiving, as transitional months such as April typically have widely varying weather. At least for April 2015 no protests of a missing spring are warranted, as temperatures reached into the 60°s and 70°s for several days in each week of the month, yet minimums were at times in the 20°s and 30°s throughout April. There was only one major rainfall event, but there were occasional showers. A summer-like squall roared through the state late afternoon on the 22nd, followed the next day by daytime snow flurries. Now that is spring weather!

April was a rather dry month, with statewide precipitation averaging 2.74". This is 1.32" below the 1981-2010 average and ranks as the 32nd driest April since 1895 (121 years). The average temperature of 51.5° was 0.3° above average and is tied with 1958 and 1973 as the 36th mildest. An almost statewide freeze on the 25th did not appear to do much, if any, damage to emerging vegetation. Overall, the slow emergence of vegetation following the cold March jumped ahead to near-normal timing during a warm mid-month week, only to slow again during the cool last week of April.
