When is the heatwave in the eastern US going to end?

Hello, non-American here. I heard the east was having a brutal heatwave for the past few weeks and I'm wondering if there's any indication when it will end?

I checked one of the cities affected (Washington DC) and going forwards for the rest of July and most of August the temperature never goes below 90F/32C. Is this normal for summer or is this lack of dipping temperatures due to the heatwave?
