Fall River, MA Daily Water Report — October 4, 2026

Fall River gets a firm green light for small-boat, paddle, and dive plans today, with an important footnote: it is wonderfully flat, not wonderfully windy. Boating rates 8.7/10, kayaking 8.5, and diving 8.8, all supported by a remarkably slight 0.1 m sea state, only 0.12 m of southeast swell, light ENE winds, and no rain indicated. That is a civilized October water day—provided everyone still treats the tide and cool morning air with appropriate respect. The cleanest all-around window is early, from dawn through the 7:46 AM low tide. Winds remain light overall, though gusts are forecast to top out near 15.4 knots around 9 AM, so paddlers and operators of lighter craft should not mistake the flat water for a permanent guarantee. A second useful stretch develops around the 3:15 PM high tide, with afternoon air reaching about 18.3 C. Marine SST is 18.4 C, mild by the calendar, but the air begins near 8 C; dress for the launch, not just the water. Anglers have a notably better setup than the last few days, with fishing at 7.7/10 after 6.3 yesterday and 5.4 on Friday. The strongest timing overlaps the 6:35–8:35 AM solunar major period and the morning low, while the 1:05–2:05 PM minor period leads into the afternoon high. Pressure is falling from a relatively high 1020 hPa, another ingredient in the fishing score, but that score is a planning guide rather than a promise. Chlorophyll is elevated at 2.28 mg/m³, though it should not be read as a direct report of fish activity. Sailing is the odd one out at 5.8/10: the sea is tame, but the 1.2–7.9-knot wind range offers more drifting than driving. Surfers should look elsewhere; no surf score is supplied, and 0.1 m waves offer no meaningful case for a session. Compared with yesterday, boating eases from 9.2 while fishing improves sharply; diving and kayaking hold steady. Monday stays mostly dry but turns breezier, with waves building to 0.4 m. Tuesday looks quieter again but much colder at dawn. Best bet: launch near dawn for glassy water, finish before the midmorning gusts get ideas.
