The last of this winter’s King Tides are this weekend.
The King Tides are caused a few specific times during the year when the moon is closest to the earth. King Tides – when normal high tides are higher than usual – occur once a month during the winter and summer. The first of the winter King Tides occurred in late November, December and early January, when it coincided with a big winter storm.
Highest tides this weekend are 8.6 feet at 11:36 a.m. Friday; 8.7 feet at 12:30 p.m. Saturday, and 8.7 feet at 1:20 p.m. Sunday.
The low tides this weekend are small minus tides occurring after dark: –0.5 feet at 6:44 p.m. Friday; -0.8 feet at 7:27 p.m. Saturday; 0.7 feet at 8:09 p.m. Sunday.
There is a group called the Oregon King Tides Photo Project that enlists volunteers to photograph specific areas of the coast over time to help document sea level rise and erosion.
