Surfers, grab your boards.
Rare swells more than 10 feet are expected at beaches from Ventura County down to Orange County this weekend as two frontal systems are expected to merge in the Southland.
"Good size" waves are building from a northwest system moving in from the Bay Area meeting a south-southwest front, with the biggest waves arriving Sunday, according to Surfline.
Angelenos will want to check out Malibu and Zuma beaches for the best surf, while Orange County surfers will want to ride swells at Huntington and Newport Beaches.
Overhead swells are expected at most beaches.
For those non-surfers, Southland residents can expect cool temperatures and nighttime showers this weekend as the frontal system makes its way south from the Bay Area.

Rain is expected to start falling on Ventura County around 7 p.m., while most parts of Los Angeles, Orange, Riverside and San Bernardino counties should see showers a couple hours later, but the rain won't last long.
"Not a lot of rain with this forecast," said NBC4 Weathercaster Byron Miranda. "I think we'll pick up somewhere up to a tenth of an inch. … Some areas may pick up more than that."
The showers are expected to end around midnight.
