Yeah, it has been extraordinarily humid, muggy, and sweaty to start the summer on the East Coast...
For y'all, Southern (and maybe West Coast) folks that's normal but on the East Coast we'll have the usual 80+ degree days, the difference is that the humidity (dew points) levels would normally be in the 50s and low 60s so for example despite it being say 85+ degrees on a Wednesday, the temp wouldn't feel so bad because of those low dew points.
The 85+ degree temps aren't the problem it's those humidity/dew point levels being very high in the 70s.
