There are cyclical behavior in droughts, but the processes responsible for these cycles aren't well known. A common pattern is that El Niño years are more likely to be wet, while La Niña years are more likely to be dry, but there are dry El Niño years and wet or at least average La Niña years. Generally speaking, predicting and explaining year to year climate variability is a field in its infancy.

In this article figure 3 has 2 images that cover northwest Mexico and most of Baja CA - one from long ago, reconstructed, and one with recent data.
The paper thinks there will be a "need for regional sustainability planning for the future." [last sentence of the abstract]
