With it getting hot 2 things are going to happen.  Chinch bugs are about to become active and yards are about to get dry.  It’s important to know the difference between the two because the can easily be confused and look very similar.  It’s not uncommon for people to think their grass is dry and needs more water.  They turn the sprinklers up higher only to find the issue doesn’t get any better.  It’s not until the large parts of the grass die off that they realize it is actually chinch bugs and they need an insecticide, not more water!  Hope this helps!
