The statewide rain totals for the 2025-2026 water year so far rank 6th out of the years of the 21st century, so aren't that remarkable in context. Do you live in a place that got slapped with a peculiarly high rainfall?
Weren't there massive floods, in the Bay Area, last year?
I wonder if overall rainfall doesn't tell the whole story. From my experience in SF (and admittedly CA is big and people will have very different experiences) there has been an enormous amount of rainfall early in the season and then another enormous amount over the holidays, but the rest has been dry. The total may not be that much but the acute heavy storms have been pretty intense.
California is big! That's also why there have technically been small parts of California which have been in drought for the last few years while most of the state is in good shape.
This year, Southern California is having a wet year while most of Northern California is having a relatively dry one.
