Valdez, AK Daily Water Report — August 27, 2026

Today is a prime late-summer day for getting on the water in Valdez, though exactly which activity you choose matters. The big takeaway: kayakers and boaters have an exceptional window, while the rest of us get decent but not spectacular conditions. Winds are negligible—representative southwest breeze at just 2 knots, gusting to 7, with a day range of barely half a knot to 4 knots. That calmness is the star of the show. The strongest gust clocks in at nearly 16 knots during the early morning hour of 6 AM, but that’s a brief spike, not the story of the day. Waves are flatlining at zero meters from any direction, with no swell or wind waves to speak of. For paddlers, that’s about as good as it gets around here—the kayaking score hits 9.4 out of 10, and boating follows close behind at 8.8. If you own a skiff or a kayak, this is your morning. Divers get a solid 7.5, buoyed by the flat seas and light wind, though the water temperature data is missing from the marine observations, so we’re working with a reconstructed anomaly showing it’s 0.6 degrees Celsius warmer than average. Without a direct reading, treat that as a nudge toward favorable, not a guarantee. Surfers and sailors see scores in the mid-4s, and that’s honest—no waves means no surf, and while the wind is light enough for a drift sail, it’s not enough for real performance. Fishing sits at 6.6, and the solunar setup suggests the major periods around midday and just after midnight offer the best biological timing, but there’s no tide data to sharpen the picture. The waxing gibbous moon at 98% illumination will cast plenty of light through the long evening—sunset isn’t until 21:13, with dusk stretching past 10 PM. One hazard worth noting: visibility is listed at 62 kilometers in the air, but that’s atmospheric clarity, not what you’ll see underwater. Don’t confuse the two when planning a dive. Pressure is stable at 1015 hPa, and cloud cover sits at 82%, so expect a mostly overcast but dry day—the representative precipitation is zero, and no rain windows appear. Looking ahead, the pattern holds through the weekend. Friday and Saturday bring identical flat seas and even lighter peak winds, but precipitation chances climb to 100% both days. Sunday looks drier with a 18% chance of rain and slightly warmer air topping 17 degrees Celsius. Monday cools off again with another wet chance. Bottom line: if you want glassy, dry conditions with long daylight, Wednesday is your best bet for weeks.
