CatchWindow fishing intelligence

Sitka, AK Daily Water Report — October 4, 2026

Sitka gets a qualified go today: workable for fishing, boating and sailing if crews are prepared for a wet, gusty, lumpy October day, but it is not the easy-water option. Kayaking and diving are more marginal, with 1.5–1.8 m seas, rain through the day and limited atmospheric visibility around 2.4 km demanding conservative decisions. The most useful overlap arrives around the morning major solunar period, 7:01–9:01 AM, nearly matching the 8:49 AM high tide. Fishing rates 6.2/10 under the model, helped by that timing, though falling pressure near 1003 hPa and a southeast wind that can vary well above its representative 8 knots keep the day from being a clean standout. The evening major period, 7:01–9:01 PM, brackets the 7:50 PM high tide, but it also runs into dusk and then darkness; daylight ends at 6:32 PM, with dusk fading by 7:10 PM. For boaters, the 5.9/10 score reflects a manageable but unsettled mix: 1.54 m representative waves at 7.25 seconds, a 1.1 m southwest swell, and short 0.44 m wind waves. The calmest wave height is only about 1.46 m near 3 PM, so “calmer” is relative, not glassy. Sailing earns 5.8/10, with enough breeze to work with but a broad gust spread and full cloud cover making sail handling less forgiving. The strongest modeled gust, 40.6 knots, occurs at midnight; it is a reminder to check current conditions rather than treating the representative wind as the whole story. Diving is a middling 5.5/10 and kayaking 5.2/10, both held back by sea state, rain and wind. The 10.9 C marine SST is mild for the season, about 0.9 C above average, but it does not erase exposure concerns. Atmospheric visibility is poor; it says nothing about underwater visibility. Wildlife scores best at 7.4/10, particularly around the morning and evening tide-and-solunar windows. Compared with yesterday, wind is lighter and boating, fishing, diving, kayaking and wildlife scores improve, though sailing drops sharply from 8.2/10. Looking ahead, rain remains likely through Wednesday and seas build to 1.7–1.9 m Tuesday before a notably quieter marine stretch develops Thursday onward. Best bet: fish the 7–9 AM high-tide window, then let the weather—not optimism—decide how long you stay out.
