For 2017 U.S. Fish & Wildlife Service offers regularly scheduled Low Tide Interpretive Walks during the months of May, June,July and August. You can walk among the rocks on Bandon Beach at Coquille Point or in Charleston at Simpson Reef near Sunset Bay. Click on the following link to see the scheduled tidepool walks for this summer.
Best viewing times strongly depend on the tides. This determination is generally based on the tides being near -1.0 foot or lower after about 7 AM. Some organisms that are seen only a few hours per year are seen at these times.
Tide forecasts may be obtained for numerous Oregon locations at Salt Water Tides and entering your desired location, month and date. You may also access tide forecasts posted on the website of the Hatfield Marine Science Center of Oregon State University at Yaquina Bay in Newport, Oregon: 2017.
Tide corrections to the Hatfield Marine Science Center information for other locations are also listed at their website. For example, the correction for Bandon Beach at the Coquille River mouth in Bandon means that the low tide occurs 6 minutes earlier and has a height of 84% of the height shown for Yaquina Bay.
