The County of Los Angeles Underwater Unit maintains and provides educational services and experience programs to train and educate SCUBA divers, freedivers and dive leaders in local oceanographic patterns and processes for safe exploration of the coastal and offshore island waters of Los Angeles County. Certification programs emphasizing critical watermanship skills, repetitive acclimation and exposure to the differing seasonal turbulence patterns are also offered with no particular affiliation to any agency.
The Lifeguard Division of the Los Angeles County Parks & Recreation has responsibility for the direct oversight and management the following Los Angeles County Parks & Recreation Underwater Unit programs:
- Rocks, Rips, and Reefs (3R’s)
- Basic Scuba Course
- Advanced Diver Program (ADP)
- Underwater Instructor Certification Course (“UICC”)
3R’s (Rocks, Rips and Reefs)
Program Information
The 3R’s (Rocks, Rips and Reefs) is a public service designed to educate and update free dive & scuba divers on the seasonal environmental awareness considerations for diving in Los Angeles County to site specific shore based diving considerations, current year swell & surf patterns and safe practices for popular local dive sites in Los Angeles County. This program offers several sessions, from May through September at various county beaches
A key program goal is to assist participants in identifying and recognizing the precipitating events that cause accidents in shore based diving environments so they can be avoided or mitigated.
Each Ocean Session begins with a short land based educational seminar covering the local dive site bathymetry, shore based entries and exits, certain aspects of the local marine environment, and other valuable, site-specific information. Conditions permitting, the seminar is followed by an in-water demonstration and practice session for qualified participants that includes a skin diving tour of the actual dive site.
Local on duty Lifeguards also provide a briefing on EMS and local hazards observed and at selected sites, there is an opportunity for Baywatch boat boarding, briefing and tour at selected locations.
How to Utilize Forecasting Tools in Dive Planning
The presentation centers on current year weather, swell and surf patterns and safe practices, with examples of popular dive sites in Los Angeles County utilizing NOAA and CDIP forecasting tools and real time data feeds from NOAA & CDIP buoy arrays.
If the list is empty, our 3R’s programs have concluded for the year. New dates are posted in December.
