The oceans normally undergo a cycle of patterns in ocean currents which also manifest surface temperature warming and cooling. You've probably heard "El Niño" and "La Niña" during weather forecasts.

The cycle is very irregular and I doubt we have good prediction models for it. However, the observations of the ocean currents line up very well with ocean surface temperature readings.

On it's own, the ENSO cycle would not cause an overall trend of warming. However, it is very capable of being the cause of the "bands in the data" that you noticed.
