Central NJ, 7a. Grass was 100% green a few weeks ago, now there are brown spots all over. Tons of rain the past few weeks. They're not very brown, even hard to see in the picture. No rings to indicate fungus. Not large enough patches to be grubs. Help!

Same issue here in St. Louis – following
I would ask your neighbor across the street what he is doing. Also looks like he uses an extra wide broom.
Cutting grass too low possibly. Just happened to me
Fungus?
I recommend fertilizing once a month and making sure it’s getting enough water.
Either fungus or lack of iron. My grass was a yellowish-green in some areas; sprayed chelated iron and greened right up. I had already put down fungus/grub pellets the prior week so I knew that wasn’t the case with my lawn.
Is it a new lawn? I am landscaper in Southern California, a lot of new lawns are not rototilled properly, we have to aerate and loosen up the top soil on new lawns as they brown up often.
Red thread fungus? I’m in 7A and a wet May with such low lows and high highs has let red thread spread a bit.
Your neighbor across the street is killing it. Step your game up son!
Most likely disease but really hard to tell without a close up. Look for lesions on the individual leaves themselves.
Your lawns fine dude
fungus doesn’t have to be in rings or circles, pull the blades to examine them to have a better idea what’s going on, can’t tell much by these photos
Grubs maybe?
Your neighbors yard is amazing looking. Sorry I don’t know the answer to your question.
Chinch bugs
Almost certain its fungus. Keep cutting in the opposite directions and maybe a tiny bit low, just while the ground is moist and wet. Let that air in at those root.
You should be good as long as you don’t get a week or 2 more of rain.
I’d personally give it a light dose of fertilizer now to help it fight what’s happening.
I’m in 7b Central VA and have the same thing showing up this week and getting worse with all the rain. I wasn’t sure at first but now confident it’s some kind of fungus and going to spray first chance.
It’s not aerated well and probably compacted soil. So rain just sits on the surface more encouraging shorter roots. I would apply a wetting agent to let the water go down deeper
Uhh grass
The guy across the way has patches probably from dog walker. It all starts with the soil. Earlier I said don’t add chemicals but until you can aerate you can try Jonathan Green Mag-I-Cal or plus.

Looks like maybe you’ve just gotten some rain eh?
In the NE it’s been a very wet month so it may just be the excess rain in your area.
