Southern California will get some waves and unseasonably warm weather to go with them this week.

According to the National Weather Service, a series of storms southeast of New Zealand has generated a 40-foot swell from the south-southwest that has traveled nearly 7,000 miles in the past 12 days. The swell, which extends south to French Polynesia, will bring five- to six-foot waves to south-facing beaches in Ventura and Oxnard and three- to five-foot waves in Los Angeles County. Santa Barbara, which is protected from the south by the Channel Islands, will be mostly unaffected by the swell.

Bruce Rockwell of the NWS forecast and weather office in Oxnard said the swell will also bring dangerous rip currents.

“We’re advising swimmers to avoid the water unless they are extremely skilled, but even then we don’t recommend it,” Rockwell said. “Five-foot surf can cause some problems.”

A high-surf advisory has been issued for today. The swell is expected to start subsiding on Wednesday but persist through Friday.

The NWS has also issued a special weather statement for record-high temperatures across Southern California. A ridge of high pressure across the western states has caused a heat wave expected to continue through Wednesday.

Temperatures on Monday ranged from the upper-70s to 80s near the coast and were in the 90s inland. The NWS warns that the combination of a prolonged period of high temperatures and relatively low humidity will create a heightened fire danger through Thursday.
