Your reference is for Napa. The reference for Paradise from the same site[1] shows rain in May and October, as I mentioned. SST anomalies, like all anomalies, cannot be interpreted without first understanding the distribution of anomalies. Examining 5 sequential years is not as helpful as you might want, especially since 2015 was an El Niño year. And as a Californian let me assure you the tails on all our weather distributions are enormous. We only get a dozen storms[2] on average. But just a few here and there can easily change that to six and a drought, or 24 and a deluge.

Consider the idea rather than the absolute value.
