King Tide Morning

The Kitsap Sun said the last few days have seen the highest tides of the year, calling them “King Tides.” Further, it invited anyone so inclined to post tide photos on a flickr page to help the state Department of Ecology document them. Until this morning I wasn’t able to participate. The tides have reached maximum height well before sunrise, so it’s been too dark out to do much with my inexpensive digital camera. The photo included above was taken right at high tide (7:56 AM) and shows a 14.0-foot tide at the north end of Mud Bay. There was enough light for the Mud Cat to point out the water’s edge.

I’m a bit confused. In January 2010 I wrote a blog entry about perihelion tides, extreme high tides that occur when the earth is closest to the sun and the moon is also exerting maximum gravitational effect on the tidal range. For comparison the photo I posted last year shows water on the land side of the small bulkhead behind the Mud Cat. That high tide was listed as 13.8 feet. So are the tide charts incorrect or did something else like storm surge or heavy rain cause the higher water level?
