Tiny sample size, but I wonder how the summers in those years turned out.  I know '77 was the year with the brutal heatwave and legendary blackout.

Temperatures approached and reached record levels across parts of the region yet again today. Central Park registered a high of 89°. Newark reached 90°. Daily records were set at Atlantic City (91°), Baltimore (91°), Norfolk (92°), and Philadelphia (91°).

Readings will return to the upper 70s to around 80° tomorrow, upper 60s on Saturday and upper 50s to lower 60s on Sunday. A sharp cold shot is possible early next week.

Generally dry conditions will also persist through at least Saturday. Some showers or thundershowers are possible Sunday afternoon into Sunday night.

The ENSO Region 1+2 anomaly was +1.5°C and the Region 3.4 anomaly was +0.2°C for the week centered around April 8. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.30°C and the ENSO Region 3.4 anomaly has averaged +0.07°C. Neutral ENSO conditions will continue through at least mid-spring.

The SOI was +1.51 yesterday. 

The preliminary Arctic Oscillation (AO) was -0.115 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 85% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 56.1° (2.4° above normal). 

Supplemental Information: The projected mean would be 3.1° above the 1981-2010 normal monthly value.
