Another Round of King Tides

Posted: December 30th, 2013

Another round of King Tides are upon us. Beginning this Thursday morning and lasting through next Tuesday, predicted high tides in Seattle will surpass 12.7 feet MLLW. The highest predicted tide (13.29 feet MLLW) is predicted to occur at 7:22 AM on Saturday.

Fortunately current weather forecasts call for relatively high pressure, which will suppress predicted water levels and likely prevent coastal flooding. With future climate change and sea-level rise, however, impacts like those that occurred during last year’s King Tides are certain without the added effects of wind and low pressure.  In fact, the best available science projects that the water levels pictured above (Nick Adams, West Seattle Blog) will be associated with an average King Tide by as soon as the year 2033. 

SPU will continue to closely monitor coastal conditions and combine the information with ongoing assessments of potential impacts to enhance our resilience to climate change. For more information, please contact SPU’s Climate Change team.
