Right and also that horrendous power outage in 1977, which was timed right around that big heatwave.
2002 was wall to wall hot, beginning in April and lasting through September. Droughty too, I remember yellow grass here.
Those were the el nino exceptions. I think 1994 was too, but early on. It started out as hot as 1993 was but then it cooled off later on, except Philly had a historically hot summer like the previous year.
I believe 1993 was the hottest summer out of the 90s, three straight days above 100 and a 10 day super heatwave.
