Port Orford Tide Pools 2026: Battle Rock Beach & Oregon's Deepest Winter Low Tides

Port Orford is the Oregon station where winter wins. The August 11–14 dawn run — the year's last morning minus tides, bottoming at −1.74 ft MLLW on Wednesday, August 12 at 6:19 AM (NOAA station 9431647) — is the summer headline. But the deepest daylight water of 2026 arrives Christmas Eve: −2.21 ft at 6:14 PM, nearly half a foot below anything summer managed, the deepest daylight low on the Oregon coast this king season.

Every other station guide in this series builds to a summer morning. This one can't, honestly. At Port Orford — the southernmost Oregon station we compute, on the far south coast where US 101 bends around a natural deepwater port — the four deepest daylight lows left in 2026 all land in November and December, at dusk. The Oregon hub calls the king-season depth chart a staircase that deepens as you go south; Port Orford is the bottom step.

When is the lowest tide at Port Orford in 2026?

The eight deepest daylight lows remaining in 2026, ranked by depth, with the score that folds tide depth and daylight together:

Read the score column against the depth column and the station's whole character is there. The four deepest rows — all winter, all dusk — score in the 60s because so much of their water arrives after sunset. The August rows give up half a foot of depth and score 7 to 17 points higher, because a 6 AM low in August has a full morning of light behind it. At Newport, 130-odd miles up the coast, this argument ends in a photo finish (summer beats winter by 0.003 ft). At Port Orford it isn't close: December 24 beats August 12 by 0.47 ft — the biggest winter margin at any Oregon station we compute — and still loses the usability contest.

The near-term windows: a July warm-up, then the last dawn run

The eight best windows of the next 60 days, computed 2026-07-21 from NOAA station 9431647. Scores (0–100) weigh tide depth and daylight together.

The late-July set is the gentle one: four consecutive mornings under −0.5 ft at civilized hours, including Saturday, August 1 — the only weekend day in the table — with an 8:19 AM low that asks nothing heroic of anyone.

The August 11–14 run is the serious one, and as everywhere on this coast, it rewards the alarm unevenly. Tuesday the 11th is nearly as deep as the peak (−1.72 ft) but its 5:34 AM low comes about 46 minutes before first light — around 6:20 AM, derived from the window's daylight minutes — so you'd arrive in the dark and meet the low at half-light. Wednesday the 12th is the pick: deepest water of the run, with the low landing almost exactly at sunrise. Thursday the 13th matches Wednesday's score of 80 by the opposite trade — a shallower low, 37 minutes after sunrise, at a kinder 7:00 AM. Port Orford's low comes earliest of the four Oregon stations on August 12 (6:19 AM here, 7:04 AM at Garibaldi — the tide sweeps the coast south to north in 45 minutes), which is why the southernmost station gets the fewest daylight minutes from the same event. The mechanics behind every deep dawn low on this coast are in the dawn-lows guide; this run's day-by-day windows are on the August calendar.

After Friday the 14th, that's it: no Oregon station we compute sees another morning minus tide below −1 ft in 2026. August has 12 daylight minus tides at Port Orford; September manages 3.

The shores: Battle Rock, Rocky Point, Agate Beach

Battle Rock Beach is the one you can't miss — the wayside park sits right on US 101 in the middle of town. "Battle Rock Park is named for the historic battle that took place at Battle Rock where the Qua-to-mah Native Americans fought Captain William Tichenor's men in 1851," per Travel Oregon; today, per the local chamber, "there is a city-maintained Visitor Center and restroom there for information about the park and the area." "The beach is just a short walk away from the parking lot," notes Oregon Discovery's park guide, and "day-use fees: none" — no gate, no pass, town amenities a block away. The same guide points low-tide visitors toward the port side of the cove, noting that north of the dock "there is an intertidal area with many colorful marine creatures" — sea stars, anemones, and urchins among them — in tide pools.

Rocky Point, at the south end of that stretch, is where the rules change. The Redfish Rocks Marine Reserve is "located off the south Oregon coast between Rocky Point and Coal Point, just south of the town of Port Orford," per Oregon's marine reserves program — 2.7 square miles of reserve with harvest restrictions in place since January 1, 2012, and a rule as short as Otter Rock's: "No take of animals or seaweeds. No ocean development." Rocky Point is the reserve's northern boundary, so if you work the rocks down that way, treat the shore as look-only and leave everything where it lives. The program's own suggestion for seeing the reserve is from above: "Visitors can find views overlooking the reserve from nearby parks at Port Orford Heads, Battle Rock, and Humbug Mountain."

Agate Beach is the north-of-town counterpart, reached through Tseriadun State Recreation Site at Garrison Lake — "open for day use year round," per Oregon State Parks, which counts "agate collectors" among the regulars and notes "there's a reason the community calls it Agate Beach." It's gravel-and-sand beachcombing ground rather than pool country; a few minutes further north, Paradise Point State Recreation Site earns the same billing — "The beach is great for beachcombing; it's not unusual to find floats and agates here." If the gravel is what you're after, the agate-hunting guide pairs these beaches with the winter windows that expose them.

What you'll find in the pools

Here the honest answer is: the record is nearly blank, and that's the interesting part. Recent research-grade iNaturalist reports within a few kilometers of the station over the last 60 days total exactly two — a Black Leather Chiton (Katharina tunicata) and a Gumboot Chiton (Cryptochiton stelleri), one observation each. Compare La Jolla's 699 reports over the same period, or Newport's 212. That's not because the shore is empty; it's because almost nobody is looking. Port Orford's intertidal sits beside a marine reserve that has been closed to harvest for over a decade, at the least-visited end of the Oregon coast. If you carry a camera down at low tide, you will likely be the only person recording what's there.

Winter: the deepest daylight water in Oregon

From late October the deep water moves to dusk, and Port Orford's dusk runs deeper than anywhere else on the Oregon coast. The five lowest daylight lows of the October 2026–March 2027 king season:

Computed 2026-07-21 from NOAA station 9431647. In the December run, the low itself arrives after dark — you work the falling tide in the last of the light.

The Christmas Eve row is the deepest daylight low at any Oregon station this king season, but read its daylight column: 69 minutes, all at the front of a window that opens at 3:40 PM, with light gone around 4:49 PM and the −2.21 ft low not arriving until 6:14 — an hour and a half after dark. December 23 is the more usable sibling: light to about 4:48 PM against a 5:26 PM low.

The row worth circling is the last one. January 21, 2027 — a −1.89 ft low at 5:12 PM, with daylight running to about 5:17 — is the only window among the five season-lowest daylight lows at any of the four Oregon stations that reaches the Great band. The low arrives five minutes before the light runs out: you get real depth and you get to see it, a combination the rest of the coast's king season never quite delivers. These dusk tides ride the same alignments as king tide season, when winter's highest highs drain to the year's lowest lows a few hours later.

How to work the window

In summer, use the arrive-by column: be on the rocks about an hour before the low and follow the water out, keeping your exit line in mind as it turns. In winter, invert the advice — show up when the window opens and work the falling tide while you can still see it, because the low itself may arrive after dark. These are predictions, not observations; check conditions before you commit to a scramble, especially on a south-coast shore known for winter swell.

One honesty note: station 9431647 sits at the port itself, in the cove sheltered by the Heads, and its predictions are the standard reference for this stretch of coast. Battle Rock Beach is essentially next door, but Agate Beach and Paradise Point are open shore a couple of miles north, so the exact minute of low water there can differ a little from the table — margin the arrive-by column already builds in.

The station page carries every computed window, the trip picker finds multi-day runs like August 11–14 automatically, and the Oregon minus-tide calendar puts Port Orford beside Garibaldi, Newport, and Charleston month by month. One town, one rock with a war named after it, a reserve nobody may harvest, and a shore almost nobody has recorded — bring the camera, and maybe be the first.
