With temperatures climbing ahead of Labor Day weekend, forecasters are advising beachgoers to be cautious of strong rip currents and powerful surf along Los Angeles County beaches.

Some inland areas could reach up to 110 degrees over the holiday weekend, while coastal highs are expected in the upper 70s to low 80s, according to the National Weather Service.

Thousands of residents are expected to flock to the coast to escape the heat.

On Saturday, a mixed south and north swell will bring a high rip current risk and stronger surf, with wave heights building to three to six feet in the late afternoon, according to forecasters.

A high rip current risk means life-threatening currents are expected.

Low tide will be at 7:17 a.m. Saturday, and water temperatures will be slightly cooler at 66-68 degrees.

For boaters, a small craft advisory was in effect from 7:57 a.m. Friday until 3 a.m. Saturday for offshore waters between Santa Cruz and San Clemente islands.

The NWS advised inexperienced mariners, especially those in small craft, to avoid the ocean during the advisory period.
