What happened

The episode as NWS MTR wrote it up.

A rip current at Martin's Beach in Half Moon Bay swept four people out to sea on Saturday November 25. The four had gotten too close to the water, lost their footing, and went into the water. Two of the people self-rescued, the other two, a 5-year-old girl and her grandfather (a 54-year-old man), were swept out to sea. The timing of the event is unclear, but the Coast Guard search started at 1:20 PM. The girl was recovered and taken to the hospital, where she was pronounced dead. The man remains missing, and the search was called off the next day. At the time of the incident, the SF Bar buoy (46237) reported wave heights of 7 to 8 feet at 18 to 20 seconds. Winds were offshore (out of the E/NE) generally around 10 mph near the Half Moon Bay coastline.

(Today through Thursday)
Issued at 925 AM PST Sat Nov 25 2023

Hazardous seas continuing for small craft vessels between 10-14

relatively light over the waters through most of the first half of
the work week.

&&

.BEACHES...
Issued at 4:00 AM PST Sat Nov 25 2023

Long period waves will be energetic in the surf zone leading to
an increased risk of sneaker waves especially for northwest-facing
beaches. The Beach Hazards Statement remains in effect for the
coastline from Sonoma County down to Monterey County through 8 AM
Sunday. Sneaker wave risk diminishes by Sunday afternoon as swell
period decreases, but the waters may still be turbulent with larger
breaking waves, so caution is still advised. In addition to the
increased sneaker wave risk, high astronomical tides are expected
this weekend, which may bring runup farther along the beach.
Beachgoers and tide poolers should use caution and watch out for
unexpected waves that can sweep you off your feet.
