Un Mar de Colores · Coronado, CA
Commercial after-school programs charge fees or offer shallow enrichment. We charge nothing with depth.
Un Mar de Colores runs its flagship Ocean Stewards After-School Program for Coronado teens ages 13–17, in partnership with Coronado Unified School District. Students meet three afternoons a week for tutoring, environmental literacy, and career exploration, with a Thursday beach day at Coronado Central Beach. Our Coronado cohort draws primarily from Coronado Middle School. Transportation, meals, tutoring, and surf instruction are entirely free.
Tuesday–Thursday, year-round · Completely free
Coronado Central Beach's wide, flat sandbar and year-round lifeguard coverage make it a welcoming teaching location for our South Bay cohorts. We partner with Coronado Unified for middle school recruitment and with the Silver Strand State Beach for overflow locations. The proximity to North Island Naval Air Station also means we serve military-family youth through our Ocean Stewards program.
How much does after-school tutoring cost in California? Commercial centers often charge $40–$80 per hour. Un Mar de Colores charges $0 for tutoring, environmental science, Thursday surf, meals, and transport for Coronado teens.
Free teen programs in San Diego combining academics and ocean access are rare. Un Mar funds Ocean Stewards through San Diego Foundation grants and community donors — operating since 2018 without charging Coronado families.
Whether Coronado is on the coast or on the coast inland, we treat transportation as part of the program — not an extra parents must figure out. That's how you build real access, not marketing copy.
Cross-border watershed work matters to Coronado because Tijuana River pollution and coastal health don't stop at a border fence. Our education modules name that reality honestly.
Our primary Coronado and South Bay teaching location. Wide flat sandbar, gentle reform.
Coronado Central is consistently ranked among America's best beaches for family swimming and beginner surfing, with exceptionally clean sand that glitters from the high mica content.
In partnership with Coronado Unified School District and local community organizations, we recruit youth from 1+ Title I schools.
The Ocean Stewards After-School Program is Un Mar de Colores's flagship year-round offering for BIPOC teens ages 13–17. Three afternoons a week, students meet at partner school sites for academic tutoring, environmental literacy modules aligned with the California NGSS standards, career exploration, and college preparation. Every Thursday is a beach day — students head to The Strand, Tamarack, or Moonlight for water programming that reinforces the week's environmental science curriculum. The program runs during the full school year, connecting academic outcomes with coastal stewardship and career pathways in marine science.

“"He used to approach new activities with extreme anxiety — to the point where sometimes we couldn't even get out of the car. Now he goes much deeper into the water."”
Healthy snacks and meals are provided every session. Coronado working families don't need to pack food or pay hidden snack fees.
Round-trip shuttle transportation runs from partner Title I schools. If Coronado is inland (on the coast from the coast), weekly Thursday beach days are possible because we solve transport — not your family.
Ocean Stewards in Coronado is 100% free — tutoring, environmental science, Thursday surf sessions, healthy snacks, and transportation from partner schools. Commercial tutoring in San Diego County often costs $40–$80 per hour. We fund access through grants and donors so Coronado families never pay.
Yes. All Un Mar de Colores programs in Coronado are 100% free — including 3/2mm wetsuits, soft-top surfboards, transportation from partner schools like Coronado Middle School, and certified bilingual instruction. Funding comes from the San Diego Foundation, community grants, and individual donors. No Coronado family has ever paid for our programming.
Primary water sessions run at Coronado Central Beach. Classroom components happen at Coronado Public Library and other partner sites. All water activities happen within lifeguard-flag zones.
We serve youth ages 13–17. In Coronado specifically, our recruitment runs through Coronado Unified School District — with priority enrollment for students from Coronado Middle School. Cohorts are age-appropriate (One Ocean for 6–12, Ocean Stewards for 13–17).
No. We begin every cohort with ocean-safety fundamentals in chest-deep whitewater at Coronado Central Beach, supervised by instructors certified by the San Diego Fire-Rescue Lifeguard Division. Water comfort is built progressively. In Coronado, we also run pre-cohort pool-familiarization sessions at local community pools for students who request extra comfort-building.
Yes. All Un Mar de Colores programs are bilingual — and in Coronado, where 14% of households are Spanish-speaking, we intentionally pair at least one bilingual coach to every session. Cultural programming is delivered in both languages, and parent communications are always sent in Spanish and English.
Three ways: (1) everything is free, while most Coronado surf programs charge $50–$150 per lesson; (2) we are BIPOC-led and our coaches reflect the 32%-BIPOC Coronado community we serve; (3) our curriculum includes environmental justice, Kumeyaay coastal history, and cultural arts — not just surf skills. We exist because the ocean should belong to everyone in Coronado, not just those who can afford access.
