Adak Island, AK Daily Water Report — October 4, 2026

Adak’s call is selective rather than wide-open: sailing is the best-rated option at 6.8/10, while diving at 6.4/10 is workable only for properly prepared crews and sheltered plans. Boating (4.8) and kayaking (4.6) are the tougher sells in a brisk, gusty WNW setup. This is not a safety declaration; it is a day to respect the difference between “possible” and “pleasant.” The least lumpy water arrives near 6 AM, when forecast wave height bottoms near 1.58 m. Even then, the sea state is not exactly rolling out a welcome mat: representative waves are 1.76 m at 6.25 seconds, with 1.3 m wind waves at a short 4.4 seconds. That short-period chop, paired with WNW winds generally 12 to 19 knots and gusts up to 37 knots around 5 PM, makes small-craft comfort highly conditional. The 8.8 C marine water temperature and air that feels closer to 3 C add consequences to every wet mistake. For fishing, the 5.7/10 score gets its best timing from the morning solunar major period, 8:53 to 10:53 AM, and the evening major period, 8:53 to 10:53 PM. The late window overlaps the 10:37 PM high tide, though it comes after sunset at 8:21 PM. The low tide of -0.29 m occurs at 6:22 AM. Pressure is rising from a low early-day range, but wind remains the limiting ingredient rather than a magic improvement button. Diving scores better than the surface-craft options, but that reflects the supplied wind, wave, available clarity, and water-temperature inputs—not a promise of easy entries or underwater visibility. Atmospheric visibility is forecast near 14 km under nearly complete cloud cover, with no meaningful UV and precipitation possible through the day. Compared with October 3, today is a modest improvement for diving, fishing, kayaking, and wildlife, while boating is essentially flat; it remains well below the calmer, higher-scoring stretch earlier last week. Monday and especially Tuesday look more manageable on wave forecasts, with Tuesday at 0.8 to 1.1 m, before Wednesday’s wind and wave range turns more volatile. Best bet: sail early with a conservative plan, then let the afternoon gusts have the last word.
