Are Your Trees Dropping Green Acorns Like Crazy?
Green acorns? What does it mean, and what does it mean for the upcoming winter?
Do falling acorns have anything to do with predicting the weather? If you have oak trees in your yard, you are probably familiar with the task of raking up tons of acorns in the fall. However, sometimes many small green acorns fall from oak trees like crazy, even in the middle of summer. What does this mean and does the amount of green acorns mean anything about winter weather?
Typically, acorns fall during the autumn season, serving the purpose of planting new trees and providing food for critters. However, if green acorns are dropping prematurely, it indicates that the tree is stressed due to adverse weather conditions.
Normally, acorns ready to drop are brown or tan. Premature shedding suggests that the trees are prioritizing other tasks over seed production.
Summer Tree Stressors
A tree’s stress can be from too much rain, too little rain, a too-hot summer, or other factors. But it’s usually dependent on local conditions. In fact, just like “mast years” can happen in Virginia but not in neighboring North Carolina, the same is true for stressed-out trees dropping green acorns. It’s not happening everywhere.
Acorns and Winter Weather Folklore
In our article, 20 Signs of a Bad Winter Coming, we delve into the folklore surrounding nature’s indicators of harsh winter weather. One such sign is the profuse dropping of acorns, which typically refers to brown acorns falling during autumn months. According to tradition and lore, seeing an abundance of brown acorns falling means a severe winter is predicted.

Stood under an oak today whilst it dropped lots of green acorns, in Aberdeenshire Scotland. I was looking last year but there was none. Now I find they are no use for planting. Sigh.
Tons of green acorns have been falling at my house for about 2 weeks and it is Aug.14,2025. We have 6 acres of all kinds of oak trees, so there are small, skinny and large acorns. Also, a lot of sap/pitch is dropping. I live in N. Calif. Not sure why the sap this year.
We live on 45 acres and have the same thing going on. We too live in Northern California
Acorns in Brimfield Massachusetts are now falling. Green in color,some Brown?
Loads of green acorns and some brown ones dropping in my garden from neighbouring oak trees from late July and throughout August. I live near Twickenham in London, England.
I live in Northern California. I have tons of acorns. The wild animals can’t keep up with what is on the ground. I can’t let my horse out of the barn due to all of the acorns on the ground. I pick them up regularly, but when you have 6 acres and work full time Ican’t get to all of them.
Tampa Bay Florida area. My giant Oak has been continually dropping of acorns for several months- hundreds and hundreds-they are everyplace. Even now at the end of December!
In Northern California about 45 minutes south from Lake Tahoe copious amounts…EVERYWHERE
Here in the Sierra Foothills the acorns have been huge and falling like rain. There are so many on my steep driveway that my car does a little fishtaling coming up the driveway.
Tons of acorns on my walks in northeast Ohio also. Much more than other resent years. Covers some driveways.
I have lived on an acre and half of a wooded lot for 21 yrs. I have never never seen so many healthy acorns on the ground. I thought someone was breaking in the other night cause of the noise. No wind to disturb them, they just keep falling off the trees. Its the strangest thing I have seen in Northeast Ohio.
