Port Moller, AK Daily Water Report — August 27, 2026

Today’s the pick of the stretch for getting out on Port Moller’s waters, especially if you’re after a sail or a dive. The southeast breeze has some legs, running in the mid-teens with gusts that’ll rattle the rigging, but it’s consistent enough to keep a boat moving and a kite full. The diving window is the real sleeper: water’s sitting at 14.3°C, a hair above the seasonal average, and the wave height stays under half a meter through the afternoon, with the calmest patch near three in the morning at just 0.18 meters. That’s flat enough for a comfortable entry and exit, even if the wind picks up a notch later. Fishing scores a 6.4, nudged up by the solunar major around 13:13 and falling barometric pressure that tends to trigger a late bite. The chlorophyll reading of 3.65 milligrams per cubic meter is high, and while that’s a signal of plankton richness, it doesn’t tell you what fish are doing with it—don’t bank on a slam-dunk from that number alone. The tradeoff today is the low-cloud ceiling at 98% cover, with visibility at 12.5 kilometers and a UV index all but zero, so don’t expect a postcard. The wind-wave interval of 2.8 seconds is short and choppy, which means the 8.2 sailing score reflects favorable wind for a reach, not a clean swell for surfing—that 4.7 score is deserved. Boating and kayaking sit mid-pack because the gusts spike hard around 17:00, nearly 34 knots, and a falling glass from 1025 to 1014 hPa warns of a deepening system moving in. No historical reports exist for this date yet, so we’re flying blind on comparisons, but conditions feel typical for late August in this corner of Alaska: a brisk southerly push with a warmish marine layer. Tomorrow brings near-certain rain and waves building to 0.7 meters, which will muddy both visibility and the fishing window. The rest of the week trends cooler with persistent precipitation chances, though a drier slot on September 1 shows lighter winds and smaller swells worth watching. Best bet for the coming days: catch the window before the rain seals shut, because the sea gives you a few hours of teeth and that’s all you’ll need.
