Seattle, WA Daily Water Report — August 28, 2026

Seattle's waters are rolling out the welcome mat today, with conditions ideal for boating, kayaking, and diving. Boating takes the crown with an impressive 8.8/10 suitability, closely followed by kayaking at 8.6/10 and diving at 8.4/10. The water is calm, with wave heights barely reaching 0.06 meters, and the calmest period expected around 4 a.m. This tranquility, paired with a gentle northeast breeze ranging from 0.2 to 6.7 knots, makes for a serene day on the water. The air temperature is a comfortable 15.9°C, and with no rain in sight, it's a perfect day to enjoy the outdoors. The full moon tonight will offer a spectacular view, rising at 19:45, just in time to light up the evening skies. However, the moon's gravitational pull might affect fishing, which is scoring a decent 7.6/10, helped by favorable solunar periods from 12:18 to 14:18. Surfing enthusiasts might want to sit this one out, as the surfing score remains low at 4.5/10 due to minimal wave action. Similarly, sailors might find the wind a bit too gentle, with a score of 5.7/10, though the day’s gusts might provide occasional excitement. Compared to recent days, today’s conditions are a notch above for fishing but slightly down for kayaking and boating. The water temperature anomaly of +4.2°C suggests warmer waters than usual, which could be a refreshing change for divers exploring the depths. Looking ahead, the weather remains largely calm, with a slight chance of rain on the 29th and 54% precipitation expected. The wind will pick up slightly in the coming days, reaching 11.3 knots by September 1st, which might enhance sailing conditions. For a memorable day, grab your kayak or hop on a boat and enjoy the still waters under the full moon’s spell this evening.
