Juneau, AK Daily Water Report — October 4, 2026

Juneau’s water gets a qualified green light today: boating and diving lead the board, but this is a damp, low-visibility day that rewards conservative timing rather than a long, exposed outing. The marine forecast holds wave height, swell, and wind waves at 0 m, a notably smooth surface setup, while southeast winds run roughly 6 to 12 knots. The catch is gustiness: the representative wind is 8 knots with gusts to 21, and the strongest forecast gust reached 36.7 knots around midnight. The best all-around daylight window is the morning high tide, around 8:57 AM, overlapping the 6:56–8:56 AM solunar major period. That is the cleanest combination of useful tide height and activity timing for fishing, boating, and shoreline plans, though rain is forecast throughout the day and cloud cover is complete. A second worthwhile window arrives near the 8:25 PM high tide, during the 6:56–8:56 PM solunar major period, but it runs into dusk after 7:07 PM and demands proper lighting and a tighter margin for error. Diving scores highest at 7.2/10 and boating follows at 7/10; kayaking is 6.4 and fishing 6.2. Those are suitability estimates, not safety clearances. The flat marine forecast helps, but 3.14 km atmospheric visibility, persistent rain, cool 7.7–11.0 C air, and a falling barometer near 1003 hPa make navigation, comfort, and exposure the day’s real work. Atmospheric visibility does not describe underwater visibility. Wildlife also rates 7.2/10, with the afternoon low at 2:22 PM offering the day’s closest low-tide opportunity. Compared with the reconstructed recent run, boating is a little below the stronger Oct. 1–2 ratings, fishing has softened from Oct. 2, and kayaking remains below the calmer early-week setup. Water is reported warmer than the recent daily values, with an SST anomaly of +1.4 C, though no usable water-temperature value is supplied. Rain and modest winds continue through Oct. 7; winds ease further from Oct. 8 onward, while rain chances finally drop late in the week. Best bet: make the morning high-tide window your plan, and let the rain gear—not optimism—set the pace.
