Atka, AK Daily Water Report — October 7, 2026

Atka’s water verdict is guarded at best: this is a weather-first day, with sailing the relative standout at 6.8/10, while boating, kayaking and shoreline plans need a hard look at the wind and building chop before leaving shelter. The narrowest workable window is early, around the day’s calmest seas near 2 AM, when wave height is forecast near 0.62 m. That is well before daylight, however, and conditions deteriorate markedly through the day. By the representative period, southerly wind is 21 knots with gusts to 42, wind waves are 1.68 m at a short 4.75 seconds, and total waves sit near 1.8 m. Gusts could reach 46.8 knots around 10 PM. This is not a day for treating a decent average as a gentle ride. For anglers, the 5.4/10 score reflects mixed timing rather than an easy water day. The late-morning solunar major period, 11:18 AM to 1:18 PM, overlaps rain, falling pressure and increasingly rough conditions. The evening minor period from 5:48 to 6:48 PM lands near the 4:20 PM high tide, but wind remains the limiting factor. The low tide at 8:54 AM offers the clearest shoreline-timing opportunity, though exposed ground and slick, rainy conditions deserve respect. Divers get a middling 6/10 despite 8.7 C marine water and a modest 0.44 m swell; surface wind waves, rain and only 3.26 km atmospheric visibility make this a poor day to confuse a score with a green light. Kayaking is 4.4/10 and boating 4.7/10, both down sharply from yesterday’s calmer reconstructed conditions, when wind was 5.3 knots and their scores reached 7.3 and 7.7. Today’s pressure is falling from a much less settled setup, and the air will feel closer to 2.2 C than its 8.5 C reading. Rain is forecast from 6 AM through 11 PM under solid cloud, with very low UV. The water is about 0.9 C warmer than average, but that does nothing to soften the short-period chop. The next few days remain wet and breezy, with waves still 1.5–2.4 m through Saturday. A more meaningful easing is forecast Sunday into Monday, especially Monday’s 0.8–1.0 m waves and lighter 11.7-knot peak wind. Best bet: if you must make a water plan, make it a short, sheltered early-morning one—and let the rising wind have the rest of the day.
