One thing that stands to me this summer is the lack of understory growth (is that the right word? I mean the stuff beneath the trees). I have almost a mile of little trails on my property and usually need to trim them back once or twice each summer. Haven't trimmed anything at all this year, except a random piece of greenbriar in a couple spots. I also use a string trimmer on the grassy parts of the trails where chiggers like to hide. Didn't do that at all this year, the grass never grew.
Same goes for the yard. Mowed once at the beginning of summer just to mulch up the leaves, there was no high grass. Mowed a second time in August, still pretty much the same, left-over dead leaves but very little high grass or weeds. An increasing amount of my yard has become moss - which is great. But the moss doesn't seem to be doing very well this summer either.
Everything seemed fine in the spring/early summer, the laurel had nice blossoms, the oaks and maples have dense leaves, acorns are coming down now. But stuff closer to the ground just hasn't grown much - from the lack of rain (I guess). It's not drying out or withering, what's there looks fine. It just hasn't grown as much as usual.
