April was 0.9 degrees chillier than average and somewhat rainier (despite there being practically no rainfall in the month's last 11 days). The chilliest reading was 38° (on 4/2), the mildest was 79° (4/14). The last time the chilliest reading was this mild was in 2012. Only two other Aprils have had a milder reading for their coldest reading: in 1878 (42°) and 2010 (40°). The month's temperature range was 41 degrees, well below the usual range of 50 degrees (since 1980, 32° to 82°). On the day the high reached 79° in Central Park, the high at Newark Airport soared to 88° (and it was in the low 70s at LaGuardia and Kennedy airports).
The month's rainfall of 4.53" was similar to that of April 2020 (4.49") and April 2019 (4.55"). Much of the rain fell from two storm systems that brought 1.15" on 4/7-8, and 2.09" on 4/18-19. Just 0.02" of rain fell between 4/20-30, which was the least to fall in the last third of April since 1942, when no measurable rain fell after 4/11 (that April is the second driest on record).
Six days had highs in the 70s, an average number, with five of them on consecutive days (4/12-4/16). The average high of 73° during the streak was twelve degrees above average. This was the lengthiest such streak in April in 11 years. The streak ended the day before Easter Sunday, which, with a high/low of 51°/41°, was the chilliest since 2009.
Finally, the last three days of the month had afternoon humidity levels that bottomed out at 11%, 9%, and 14%. The 9% reading on 4/29 tied for the third lowest in the years since 2000. This was the most arid three-day streak since March 28-30, 2007. Very low humidity was also reported on the 15th and 22nd (13% and 15%, respectively).
