CatchWindow fishing intelligence

Ketchikan, AK Daily Water Report — August 31, 2026

Today in Ketchikan, the water is calling, but with a few caveats. Boaters and kayakers will find decent conditions with scores of 6.4 and 6 out of 10, respectively. The winds are manageable, ranging from 0.4 to 7.1 knots, though gusts could hit 20.4 knots by mid-afternoon. The calmest waters will occur around 3:00 AM, with wave heights as low as 0.1 meters, but expect a slight uptick later in the day. Divers have the best prospects with a solid 7/10 score, thanks to steady conditions and a sea surface temperature of 14.6°C, slightly above average. However, visibility is a concern, with atmospheric clarity at a mere 2.32 km, so plan dives accordingly. The chlorophyll levels are high, indicating a significant bloom, which might affect underwater clarity but also suggests rich marine life. Fishing is a bit of a mixed bag today with a score of 5.2/10. The solunar periods suggest prime times between 2:11-4:11 AM and 2:11-4:11 PM, but the low atmospheric pressure and incoming rain from 1:00 PM could dampen spirits. Compared to yesterday's fishing score of 6.5, today’s conditions are less favorable. Rain is expected to start around 1:00 PM and continue through the night, so morning activities are your best bet to avoid a soaking. With the pressure falling from 1007 hPa, expect a change in conditions as the day progresses. Looking ahead, September 1st brings stronger winds and a 100% chance of rain, making today the better option for water activities. By September 4th and 5th, conditions improve significantly, with temperatures rising and minimal wind, promising excellent days for water enthusiasts. Best bet: Dive in early to catch the calm waters and explore the rich underwater life before the rain sets in.
