CatchWindow fishing intelligence

Fall River, MA Daily Water Report — August 27, 2026

Today is a solid all-around day for getting on the water, with diving leading the pack at an 8.8 out of 10, followed closely by boating at 7.9 and kayaking at 7.4. The south-southeast breeze around 6 knots, gusting to 14, keeps things lively but manageable, and the seas are running a modest 0.3 meters on a short 3.45-second period. That’s a step back from yesterday’s glassy 1.4-knot wind and 9.6 boating score, but it’s still a far better bet than the blustery 9.8-knot conditions we saw on the 24th. The water temperature is a comfortable 21.1°C, a full 1.6 degrees above the long-term average, which is helping drive that diving score. Visibility at the surface is 14.8 kilometers, and while that doesn’t translate directly to underwater clarity, the combination of light wind, small waves, and warm water makes for appealing conditions below the surface. The best window for most activities is the morning, before the wind picks up toward its midday peak near 13 knots. The calmest wave heights, around 0.14 meters, occur near 3:00 AM, but the more realistic daytime window runs from first light through late morning. The minor solunar period from 4:33 to 5:33 AM aligns with dawn, and the major period from 10:03 to 12:03 AM sits in that sweet spot before the wind really builds. Fishing scores a respectable 6.9, helped by those solunar windows and the falling barometric pressure, though the overcast sky and steady breeze aren’t ideal for pinpoint casting. Wildlife watchers should do well with an 8.0 score, especially during the morning minor period when the waxing gibbous moon is still high. Surfers will find the 0.3-meter waves from the south short-period swell uninspiring at 4.5 out of 10, and the 2.85-second period won’t build any real push. Hold off on that. Sailing at 6.3 is passable for a casual afternoon reach, but the gusty midday wind and 100% cloud cover make it more of a workout than a cruise. Kayakers should aim for the early calm and stick to protected waters as the breeze builds. The chlorophyll reading is elevated at 2.28 milligrams per cubic meter, which often coincides with richer water, but the score methodology accounts for that only in the fishing model. Looking ahead, Thursday brings a similar setup with a slight bump in air temperature and a 17% chance of rain, while Friday looks like the pick of the week with lighter wind, flat seas, and zero precipitation chance. Saturday warms up but the breeze returns. If you’re after a single, can’t-miss moment: set the anchor just after dawn, let the falling pressure and the moon’s pull do their work, and watch the water come alive before the breeze fills in.
