CatchWindow fishing intelligence

Washington, DC Daily Water Report — August 27, 2026

Today’s a strong day to be on the water, and the specifics make it an especially good one for paddlers and boaters. Kayaking and boating both land well into the excellent range, with scores of 8.5 and 8.4 out of 10, respectively, and they’re the clear headliners. Fishing sits at a solid 7.3, and wildlife viewing is right there with it at 7.7, so there’s plenty to work with across the board. The driving force is the wind. Representative SSE winds are sitting at just 5 knots with gusts to 14, but the day’s range tells a more useful story: from a near-calm 1.8 knots up to 10.1, with the strongest gust not arriving until 23:00, well after most folks have pulled their boats. That means the core daylight hours — especially the morning and early afternoon — will offer the calmest conditions. The waves are flat, zero meters across the board, so there’s no chop to fight and no swell to ride. That’s what pushes surfing to a mediocre 4.5; it’s just not a wave day. Tides are moderate, with a low of 0.13 meters just after 3 p.m. and a high of nearly a meter at 8:16 a.m. That morning flood aligns well with the solunar major period from 10:26 to 12:26, which helps explain the decent fishing score. Anglers who can get out before the midday sun really cranks — we’re looking at a high near 31°C, feeling closer to 29 — will find the best window. The barometer is falling slowly from 1014 hPa, a familiar pattern that doesn’t suggest any dramatic shift, though a brief rain window is modeled for 21:00 to 23:00, so evening plans should keep an eye on the sky. Compared to the last few days, this is a step up in fishing potential from the 6.5 and 6.4 we saw on the 25th and 23rd, though not quite matching the wildlife score of 8.0 from the 22nd. Boating and kayaking have been consistently strong all week, and today continues that run; the slight dip from yesterday’s 9.1 kayaking score is negligible. Diving data remains unavailable, so that’s a non-starter. Looking ahead, the next few days stay flat and calm through the weekend and into next week. Winds pick up slightly by September 1st, but nothing disruptive. Temperatures, however, are forecast to climb sharply, with September 1st pushing toward 39°C. That’s a heat risk that will shift the best windows earlier in the day. Best sentence: If you’ve got a kayak or a small boat, the stretch from late morning through early afternoon is your golden window — flat water, light wind, and a tide that’s working with you.
