The really high ones, i mean. We just had one at the end of September and in my records (which come from NOAA) and by observations by long time fishermen, it was the highest, non-storm perigee tide we have seen. The NOAA tide records seem to say the same with another one coming at the end of October.
Why the big deal?
We finished our final, close out beach sampling during the peak of one of those tides and the numbers were astronomical (bacteria wise). This is something that is in my sights as far as predictive modeling - washing out storm drains by high tides.
This was the highest we have seen and the only one which indicates it might b real.
We will be vigilant for future perigee tides.
