Kelp Greenling Fishing in Friday Harbor, WA
7 spots · peak May-Nov
Kelp greenling live here all year, holding tight to rocky bottom and kelp edges in 20 to 60 feet of water throughout the San Juans. We cover six spots that hold them: Cattle Point on San Juan Island, Iceberg Point off Lopez, Kelp Reef in San Juan Channel, Mackaye Harbor on Lopez Island South, Parker Reef, and Spieden Channel along Spieden Island South. Each one gives you the same basic setup, rock and cobble with kelp growing off it, and fish sitting close enough to the structure that you need to put your gear right on top of them.
The season runs May through November, with the strongest fishing from August into November. Late summer brings post-spawn fish onto shallow reefs and pushes juveniles into the nearshore kelp. Through October and November, adult males guard nests on shallow rock, which concentrates fish in water you can reach. Mid-winter is the slow stretch, when fish spread out again before rebuilding through spring.
Current runs the show. Fish the slack. You want dead slack up to about 0.5 knots, which means the window on either side of high or low water. By roughly 2.5 knots the spots are unfishable. Jigging does most of the work, with metal jigs, leadhead jigs and soft plastics, or shrimp dropped to structure. Bottom fishing with cut herring, shrimp, marine worms or clam covers the rest.
When to go
Kelp Greenling are year-round residents in San Juan Island kelp and rocky reef habitats, so abundance stays near baseline most of the year. A modest late-summer through early-fall peak (Aug–Oct) reflects post-spawn aggregation on shallow reefs and increased juvenile recruitment to nearshore kelp, with adult males guarding nests in fall further concentrating fish in accessible inshore zones.
Relative abundance by month: Jan 72 percent of peak, Feb 75 percent of peak, Mar 79 percent of peak, Apr 83 percent of peak, May 90 percent of peak, Jun 95 percent of peak, Jul 99 percent of peak, Aug 98 percent of peak, Sep 94 percent of peak, Oct 95 percent of peak, Nov 90 percent of peak, Dec 78 percent of peak.

Fish the slack
Best from dead slack up to about 0.5 knots of tidal current, and unfishable by roughly 2.5 knots. In practice that is the window either side of high or low water, when gear hangs where you put it.
