King tides are hitting Southern California beaches through Saturday making for this year’s biggest surf days.

“We expect that the tides are going to be almost the highest that we are going to expect in 2013,” Robert Balfour, a senior forecaster with the National Weather Service in San Diego told the LA Times.

King tides occur when the Earth is in alignment with the sun and the moon, pulling the oceans to their gravitational limits.
