PORTLAND, Ore. ( KOIN ) — A month after the first round of seasonal king tides walloped the Oregon Coast , a second round of exceptionally high tides is forecasted for the Pacific Northwest.
The Oregon King Tides Project forecasts the next round of king tides to last from Dec. 13 to Dec. 15. A final round of seasonal king tides will happen in January 2025.
King tides occur when the sun and moon align, adding extra gravitational pull on the Earth. That extra gravitational pull causes the Earth’s oceans to swell and increase the height of our tides.
High wind warning: 70-mph gusts possible on Oregon Coast
During a king tide, ocean tides can surpass their highest daily averages by six inches or more. These tides can cause coastal flooding and hazardous beach conditions. When combined with storms or sneaker waves , king tides can be especially deadly.
