Westport and Ilwaco are two of the most important launch points for SatFish anglers chasing albacore, so we built a dedicated chart centered on these ports to make planning simple and efficient. This map provides full coverage of the offshore grounds both north and south of Grays Harbor and the Columbia River, giving you a clean view of the water you can realistically reach on a day run, or a longer push when the weather window opens.
Instead of zooming around multiple regions, you can focus on what matters: where the water changes today and how it’s setting up relative to your run. Use SST and chlorophyll layers to locate temperature breaks and color seams that can stack bait, then pair that with bathymetry to see how structure and contours might be shaping the edge. When it’s cloudy, cloud-free composites help point you toward the right zone so you’re not waiting for a perfect satellite shot to make a decision.
Because albacore water can slide 10–30 miles overnight, this chart is built to support quick “go/no-go” planning, pick your likely lanes, build a Plan B, and adjust fast once you’re on the grounds. The end result: fewer blind searches, cleaner trolling passes, and better odds of finding life early in the day.
Frequently Asked Questions
What area does the Westport / Ilwaco map cover?
It’s centered on Westport and Ilwaco, with offshore coverage both north and south of Grays Harbor and the Columbia River. That way, you can track conditions across the full range of likely run directions.
Is this chart mainly for albacore?
It’s built with albacore runs in mind, but the same edges and seams can help for other offshore targets when conditions line up. If you fish by water changes, you’ll get value from it.
How do I decide whether to run north or south?
Compare where the best temp and color edges are setting up relative to your fuel range and forecast. The most efficient plan usually intersects an edge early, then follows it as conditions improve.
What should I prioritize: SST, chlorophyll, or bathymetry?
Start with SST to find the break, use chlorophyll to confirm the seam or bait-friendly zone, then check bathymetry for structure influence. When all three agree, it’s often a high-percentage lane.
What if it’s cloudy and the SST looks “messy”?
Use cloud-free composites or compare filtered vs. raw/less-filtered views when available to avoid missing usable data. You can still identify the general zone and refine once you get a clearer shot.
