Comments on: West Seattle scene: ‘King tide,’ tied for highest of the year https://westseattleblog.com/2014/01/west-seattle-scene-king-tide-tied-for-highest-of-the-year/ West Seattle news, 24/7 Sun, 05 Jan 2014 09:05:10 +0000 hourly 1 By: Lura Ercolano https://westseattleblog.com/2014/01/west-seattle-scene-king-tide-tied-for-highest-of-the-year/#comment-1188647 Sun, 05 Jan 2014 09:05:10 +0000 https://westseattleblog.com/?p=260985#comment-1188647 G – the NOAA site shows a change of 2mm per year. That is really tiny compared to 13 foot high tides or -3 foot low tides. I wouldn’t expect it to look different.

Count me as skeptical.

NOAA’s data makes the point that higher mean tides lead to more frequent extreme events – it’s not so much a concern that the regular water level will be higher, but that events such as last December will occur more frequently. A tide level that might have been reached every ten years could become an annual event.

Thank you! Adding that key word. And yes, that is of course what happened in December 2012, with the storm surge adding greatly to the PREDICTED tide – TR

Often when there’s a storm at sea and low barometric pressure we can have “actual” tides that can be 2′ higher than “predicted” tides.
