King Tides Could Cause Royal Splashing in S.F.

The tide is high — higher in San Francisco this week than at any point in the calendar year.

The gravitational phenomenon known as king tides hit San Francisco this week and will continue through Friday. This year’s king tide dates coincide with a major storm expected on Thursday, so rain boots may be advised if you’re visiting the Embarcadero.

King tides are a perfectly normal weather event, and not expected to cause any damage in San Francisco, other than some splashing and puddle accumulation along the Embarcadero. Marin County, on the other hand, is gearing up for the possibility of floods.

The king tides arrive in San Francisco twice annually, those dates on which the Earth, moon, and sun are close enough together to create the strongest gravitational pulls of the year. Tides will reach a high of about seven feet during the king tide, more than a foot and a half higher than average summer tides.

The highest tides for the remainder of the week are currently expected at 11:44 a.m. on Thursday and 12:30 p.m. on Friday. These times can vary slightly, so keep an eye on the National Oceanic and Atmospheric Administration’s San Francisco tide level prediction site for more information.
