Tides Differ By Location

NOAA provides information about tides (via the internet) to the public for free. NOAA is always expanding their installation of solar powered tide monitoring stations that electronically monitor tide data all over Oregon and Washington. Years ago, these new solar powered stations were not available, so we had far fewer locations to retrieve data from.

The Columbia River tides, from its mouth at the Pacific Ocean, inland to just past Portland, Oregon, are monitored by as many as 20 different NOAA tide monitoring station locations. There are around 30 different monitoring stations within a 10-mile radius of the Columbia River’s mouth. There can be a difference in tide monitoring data within distances of less than a few miles apart. Pick the wrong tide data monitoring station information and you could show up for clamming at the wrong time.  For example, if you pick the 12th Avenue Bridge monitoring station in Seaside, Oregon, it can differ from Seaside’s beach tides significantly.

For years, I have used the NOAA Monitoring Station at the Columbia River mouths North Jetty, to get Seaside, Oregon and Long Beach Washington’s, razor clamming tides, even though this is at Washington State’s side of the Columbia. The North Jetty monitoring station has location factors that make it the closest to reality for Seaside, Oregon and Long Beach, Washington, tides. For those of you Razor Clamming in Seaside, Oregon, or Long Beach, Washington tides are listed on our website at www.razorclamming.com. Good for both locations but depending on weather conditions and other factors, this can be fifteen minutes off in one or the other location (and sometimes more than a 30 minutes’ difference from one beach to another). However, this is about as good as you can get and mirrors most tide books you can buy in Seaside, Oregon or Long Beach, Washington. This is also why I say to be two hours early for Razor Clamming. The actual low tide might vary and on a rare day that it’s 40 minutes off I still have plenty of time to follow the tide out.

If you’re going to be anywhere else in Oregon, or the Puget Sound area, and you don’t trust the information you’re getting on the internet, sometimes I will call a local sporting goods store to be sure (even hotels will carry tide books in many locations and are happy to be as helpful as possible).

Information provided from this website is a result of personal experience clamming at beach and bay locations over a period of fifty-years. Information also comes from local residences providing input and advice; as well as, ongoing information from past Oregon Department of Fish and Wildlife surveys. Information will change as incoming seas have a tendency to shift, weather changes, and sand bars move. The hope of this information is for people new to clamming to have a successful first time experience. razorclamming.com is not responsible for the accuracy of this data, and the outcome, or results of your personal efforts.
