Acorn production is cyclical, with some years being quite heavy, some
moderate, and some scant. Stress can also affect production as well, so if
you had a period of drought one or two years ago, the effects could be
showing now through the heavy acorn set.
I have three oak trees about the same size, and I guess age.
Last year one tree produced a very large quantity of acorns. The other two
trees produced next to nothing.
The winter was about average here in north central Texas.
This year, all three trees are loaded down with acorns. I sure hope the
quantity of acorns has nothing to do with the severity of the winter. If it
does, this winter should be terrible.
Funny you should post about that. A tree on a back neighbors yard was
shedding acorns onto the roof of his garage. All day long these pops
and scraps would sound off as they bounced and ran down the roof
shingles. I have never noticed that before. It didn't occur to me that
there might be light and heavy years. I just assumed I wasn't around
when this tree dropped them. Interestingly, the flush of falling
acrons all seemed to happen within a day or two.

Also, remember that trees of the Black Oak group (Black Oak, Red Oaks, Pin
Oak, Scarlet Oak) take two years to ripen their acorns, so if you have a few
of those in an acorn year there will be a lot more action than when several
of them have an off-year. The Bur Oak mentioned by RJ, however, is in the
White Oak group, which ripens and drops acorns every year, although the
production of an individual tree may vary.
Here on the Blue Ridge (Zone 6B) with Black, Red, White and Chestnut Oaks,
it's sounded like popcorn is being made all the time, as they land on the
roof and the rocks, and bounce off branches, since week before last.
