The best tide pool days this winter
Go on a winter afternoon with a minus tide: the best 2026–27 dates at Cabrillo National Monument are Dec 22–24, Jan 20–22 and Feb 18–19, when the tide drops below −1.4 feet between about 2 and 4 p.m. — just before the tidepool area closes at 4:30.

The short version
- San Diego's lowest daylight tides happen in late fall and winter afternoons — the National Park Service's own advice for Cabrillo.
- The lowest of the season: about −1.97 ft at 2:51 p.m. on Thursday, January 21, 2027 (NOAA station 9410170).
- Cabrillo's tidepool area closes at 4:30 p.m., so a 3:50 p.m. low is workable but a 4:49 p.m. low is not.
- Entrance is $20 per vehicle (valid 7 days); kids under 16 are free; the park is closed Thanksgiving and Christmas Day.
- Everything in the tidepools is protected — no collecting shells, rocks or animals, and no turning over rocks.
Most visitors show up at the tide pools at noon in July and see mostly water. The trick is the calendar. In San Diego the really low tides happen in the morning in summer and in the afternoon in winter — and winter afternoons are when you can actually walk out to where the octopus and sea hares live.
When daylight minus tides happen
NPS: the best tidepooling is late fall and winter, when extreme low tides fall during daylight. Marked dates are the lowest afternoon tides of 2026–27 from NOAA.

How to time it
The Park Service suggests arriving about two hours before low tide and staying through it. Any tide at 0.7 feet or lower is good; a minus tide is when the low zone — octopus, sea stars, nudibranchs, sea hares, spiny lobsters — is uncovered. Because the tidepool area closes at 4:30 p.m. and the whole park empties at 5, early-afternoon lows are the sweet spot.
What you'll see, zone by zone
Cabrillo's three tidepool zones
| High zone | Middle zone | Low zone | |
|---|---|---|---|
| Underwater | Only at high tide | About half the time | Almost always — exposed on minus tides |
| Look for | Barnacles, limpets, chitons, crabs, mussels | Anemones, snails, whelks, sandcastle worms, surfgrass | Octopus, sea stars, nudibranchs, sea hares, lobsters, urchins |
| Verdict | — | — | This is why the date matters |
The rules (they're enforced)
- No collecting anything — living or dead animals, shells or rocks.
- Don't pry off attached animals, and don't turn over rocks.
- No containers, nets, scrapers or prying tools.
- Touch gently with one finger if at all; never pick up moving animals.
- Wear closed-toe shoes with grippy soles. Flip-flops on wet algae are how people get hurt.
- There's no cell service at the tidepools — agree on a meeting spot.
