The one problem with SSTs is that the granularity often isn't good enough on the big picture view, which would allow you to see trends. In addition, clouds can get in the way. Storms (or the lack, thereof) can also affect the temperatures and mixing. That said, when you start to see those little cyan-colored blobs start to swirl in, it's time to head to the piers and bridges. Based on my observations, the full moon also plays a big factor. They seem to head in a week or so after the full moon to feed and then, I imagine, breed at the next full moon.
