Southern California coastal residents are being urged to give extra space near cliffs and rocks due to some larger-than-normal tides.

"This week's Full Moon is creating larger-than-normal tidal swings, also known as King Tides," Los Angeles County Fire Department, Lifeguard Division posted on Instagram Wednesday.

According to the post, King Tides occur when the Earth, Moon and Sun align during a new or full moon, and the Moon is at its closest point to Earth -- a position known as perigee.

What to expect:

* High tides around 6-6.5 ft mid-morning

* Low tides near or below -0.5 ft late afternoon

* Stronger currents and rip activity, especially near jetties and piers

The fast-changing tides can cover walkways, expose rocks and increase rip current strength with little warning.

"Stay aware of the tide schedule, give extra space near cliffs and rocks during high tide, and always check in with a @lacolifeguard before entering the water," the lifeguard's post reads.
