Port of West Sacramento, Washington Lake, CA Daily Water Report — August 27, 2026

Boating and kayaking owners should clear their schedules today. With a flat-calm surface reading zero meters across the board and a representative wind of just 6 knots from the southwest, the water is offering a rare sheet of glass on Washington Lake. This is the kind of August day that makes you question why you ever complained about summer heat—air temperatures will climb from a cool 17°C at dawn to a toasty 35°C by afternoon, so the morning window from first light at 06:04 through the minor solunar period at 07:00 is prime for getting out before the sun works you over. The boating score of 8.2 and kayaking score of 8 reflect what you can see with your own eyes: no chop, no current to fight, just you and the horizon. Diving also lands a solid 7.6, and while we lack water temperature data today, the calm conditions mean easier entry and better bottom time. Anglers get a 6.2, a slight dip from yesterday’s 6.9, likely because there’s no tide-driven movement and the stable high pressure at 1012 hPa isn’t stirring things up. The waxing gibbous moon, 98% full, will pull a major solunar window from 11:30 to 13:30, which could still produce if you’re patient. Surfing remains a 4.5, and there’s no point pretending otherwise—zero swell and zero wave height mean a flat lake. That’s the tradeoff: perfect for a paddleboard or a pontoon boat, useless for a shortboard. Compared to the last several days, today’s calm is consistent with what we’ve seen since August 22, though the wind is a notch higher than the 4-knot day on the 23rd that pushed boating to a 9.3. The coming days look equally tranquil, with wave heights staying at zero through at least September 2 and winds peaking around 10-12 knots late in the week. One memorable best-bet sentence: If you’ve been waiting for a day to launch that kayak you bought in March and haven’t touched since, this is it—the lake is handing you a welcome mat.
