Cape Disappointment, WA Daily Water Report — August 30, 2026

Today at Cape Disappointment, the water activities are looking quite inviting, especially for divers, boaters, and sailors. Diving tops the chart with a stellar 8.1/10, thanks to calm seas and a mild sea surface temperature of 15.7°C, slightly warmer than usual. Boaters and sailors also have a great day ahead, with scores of 7.6 and 7.7 out of 10, respectively. The winds are steady at 7 knots from the north, gusting to 15 knots, which should offer enough breeze for sailing enthusiasts without being overly challenging. Surfers have a decent window today with a 6.9/10 score; the waves are manageable at 0.86 meters with a swell coming in from 297 degrees. However, the short period of 5.05 seconds might make it a bit choppy, so be prepared for some quick rides. Kayakers might find the conditions a bit challenging with a score of 6/10 due to the wind and current direction, but the calmest wave period near 11 PM could be an opportunity for a more serene paddle. A waning gibbous moon with 97% illumination could make for some interesting nighttime explorations, but keep in mind the solunar periods for any fishing plans. The major periods around 2 AM and 2 PM might yield the best catch, aligning with a solid fishing score of 7.1/10. As we look ahead, the weather is set to change. By September 2nd, expect a significant increase in wind and rain, with waves potentially reaching up to 2.5 meters. For today, though, take advantage of the calm before the storm. If you're looking for the best spot to dive, today is your day—clear skies, calm waters, and a touch of warmth make it ideal.
