Oregon Tide Charts

Q: Where do the Oregon tide predictions come from?

Every value comes from NOAA's Center for Operational Oceanographic Products and Services (CO-OPS). Oregon has 6 harmonic prediction stations in this directory, and each page requests the predictions from api.tidesandcurrents.noaa.gov in your browser when it loads, so the numbers are NOAA's own rather than a copy we maintain.

Q: Which Oregon station has the biggest tides?

Among the stations listed here, Astoria has the largest published mean range at 6.77 feet, while Florence has the smallest at 5.53 feet. Mean range is NOAA's long-term average difference between mean high water and mean low water; spring tides swing wider than it and neap tides narrower.

Q: Why is high tide at different times along the Oregon coast?

The tide is a long wave moving along the coast and into every bay and river, and it takes real time to travel. Two towns on the same shoreline can see high water an hour or more apart, and the delay grows up estuaries and behind inlets. That is why this page links a separate chart per NOAA station instead of pretending one table covers the whole state.

Q: Can I use these pages for boating in Oregon?

No. These are planning pages for beach walks, fishing and tidepooling. Mariners should use official NOAA charts and products at tidesandcurrents.noaa.gov. Whether any specific flat, bar or crossing is safe on foot is a local conditions question for the authority that manages that shoreline, not something a tide table can answer.

NOAA station classification

Oregon’s tides are mixed and substantial, and every bay on the coast fills and drains through a bar entrance where the tide sets the current. The lower low each day uncovers rocky reef and clam flats that the higher low never reaches.

Oregon tide chart pages

Each page below reads NOAA’s harmonic predictions live for one station: today’s curve, a 7 day high/low table with sun and moon times, and the week’s best low tide windows. Mean range and tide type come from NOAA’s published station datums, and they are worth a glance before you pick: two towns an hour apart can live on very different tides.

Mean range is NOAA’s published difference between mean high water and mean low water at each station, in feet.

Local knowledge

How tides behave on the Oregon coast

Bay clamming and rocky-shore tidepooling are the reasons Oregonians carry tide tables. State agencies publish digging and harvesting rules; these pages supply the timing, including the negative lows that make the famous digs possible.

The spread inside the state is real: NOAA’s mean range runs from 5.53 feet at Florence to 6.77 feet at Astoria. Use the station nearest the shoreline you actually plan to stand on, and expect timing to drift further up rivers, estuaries and back bays.
