This morning’s walk evidenced a higher than usual tide—although according to Metro Parks workers, yesterday’s was worse.
Mark and I arrived for our morning walk at 9 am. The drain holes in the Point Defiance Boathouse were letting water in. And twenty minutes later the entire floor was covered in water.
The promenade to Owen Beach was experiencing the surge and retreat of waves.
We did not want to get our feet wet, so we walked as far as we could before retreating ourselves and driving to Owen Beach instead. There was no beach to access!
Between the moon’s perigee and the increased angle of the sun relative to the earth (maximal at the winter solstice), gravity can do amazing things. According to the tide chart, we can expect more of the same for the rest of the week.
