Sometimes a minus is a plus! 🦀🌊🦀🌊🦀🌊
Along the Oregon coast, the ocean occasionally reveals a hidden world that most people never get to see. During certain times of the year, tides drop far lower than usual. These events are called minus tides, when the ocean level falls below the average low water mark. They usually occur during the powerful pull of a new moon or a full moon.
When these unusually low tides arrive, large stretches of shoreline that are normally underwater become exposed. Rocky reefs and tide pools appear along the coast, revealing marine life such as sea stars, sea anemones, crabs, and other creatures that usually remain hidden beneath the waves. For beachcombers, photographers, and tide pool explorers, it is one of the best opportunities of the year to see the ocean up close.
Several of the lowest tides of the season are coming this summer. The best dates to watch for them are May 17 through May 19, June 15 through June 16, and July 14 through July 15. Some of the lowest tides will occur on May 17 at 6:35 in the evening, May 18 at 7:06 in the evening, June 16 at 6:05 in the evening, and July 15 at 5:16 in the evening.
Anyone heading out to explore should go while the tide is still dropping and always keep an eye on the ocean as the water returns. Walking carefully also helps protect the delicate marine life living in the tide pools. For a few short hours during these tides, the ocean pulls back and reveals a fascinating coastal world that is usually hidden from view.
