Friday Harbor, WA Daily Water Report — October 8, 2026

Friday Harbor is a strong go for boating, kayaking and diving, with a caveat: it is a grey, cool day and the water is still very much October water. Boating and kayaking both rate 8.2/10, diving 8/10, while fishing is a respectable 6.5/10. Sailing is the odd one out at 4.7/10—not because conditions are rough, but because the breeze is too light to do much useful work. The practical sweet spot is from late morning through the afternoon high tide at 4:33 PM. Winds are forecast to stay exceptionally light, generally under 5.1 knots, with waves around a modest 0.5 m and only a small 0.08 m swell. That is friendly water for powered boats, paddlers and divers, though the short 3.1-second wind waves can still make exposed stretches feel a little fussy rather than glassy. The day’s calmest modeled seas occur near midnight, but daylight users will find plenty of manageable water before sunset at 6:40 PM. For fishing, the 10:34 AM–12:34 PM solunar major period is the cleanest daytime timing cue, followed by the 5:04–6:04 PM minor period around the afternoon high. Pressure is falling from an earlier high near 1020 hPa toward roughly 1012–1013 hPa, so conditions are not as settled as the very calm wind suggests. The water temperature is 13.9 C, 3.4 C above the supplied average, but that does not make immersion casual: dress for cold-water exposure, especially if paddling or diving. Cloud cover is complete, UV is negligible, and forecast atmospheric visibility is 13.4 km. That is useful for navigation planning, not a promise of underwater visibility. No rain is indicated, but gusts could reach 12.4 knots late tonight, after most daylight outings should be wrapping up. Compared with the recent run, boating and kayaking ease back from yesterday’s stronger scores, while diving remains close to its recent 8/10 form. The next two days bring higher rain chances and waves up to 0.7 m Friday; Sunday looks drier, and Monday currently shapes up as the quiet-water standout with 0–0.2 m waves and very light wind. Best bet: launch late morning, use the afternoon high tide as your turnaround marker, and enjoy the rare luxury of light wind without mistaking it for warm water.
