CatchWindow fishing intelligence

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

Boating, diving, and kayaking take Fall River today, scoring 9.1, 8.8, and 8.4. Open-Meteo’s current and forecast fields show a dry, lightly breezy coastal day over water that barely wrinkles, and those scores follow. Surfing is a 4.5 and can wait. Fishing is 6.1, sailing 6.2, wildlife 6: useful if you already planned to be out, not the reason to rearrange the morning. Representative wind is 4 knots from the north, ranging 0.8 to 9.3, with the day’s strongest gust, 14.6 knots, due around 18:00. Waves stay 0.1 to 0.2 meters and are calmest near 13:00 at 0.14 meters, period about 5.5 seconds, with a short south swell of 0.14 meters at 3.75 seconds and almost no wind sea. Marine SST is 20.8 C, a tenth of a degree above average. An east-setting current of 0.2 m/s is the only real push. Air runs roughly 20 to 29 C under 36 percent cloud, humidity near 96 percent, UV a negligible 0.5, atmospheric visibility 12.2 km—which is not underwater clarity—and pressure 1009 hPa and falling after 1015.9 yesterday. NOAA tides: 1.28 m at 02:02, 0.15 m at 06:51, 1.48 m at 14:27, 0.35 m at 20:01. Sunrise 06:13, sunset 19:17. Last-quarter moon. The boat and paddle scores ride the light wind, tiny waves, slack current, and empty rain column; diving adds that quiet surface. Fishing’s middling mark tracks falling pressure and only fair solunar timing rather than any drama on the water. Best windows are the dawn major period, 05:40–07:40, as the morning low drains, the midday calm around the 14:27 high, and the evening major, 17:40–19:40, toward the second low. Tradeoff: those 18:00 gusts if you linger. Versus recent CatchWindow days, boating is up from yesterday’s 8.1 and back near the high 8s and 9s of the past week; fishing has slipped a notch from the 6.8–6.9 band; diving has held at 8.8 whenever it scored. Saturday cools with a 13-knot peak and a 13 percent rain chance, then lighter, drier air through the 8th. Waves stay tiny until the 10th, when they may reach 0.6 meters as rain chances rise. Best bet: take the boat or kayak through the afternoon high, when the surface is at its smallest and the light still has hours left.
