CatchWindow fishing intelligence

New Bedford Harbor, MA Daily Water Report — October 4, 2026

New Bedford Harbor gets a clear green light for small-craft time today, with boating and kayaking both rated 8.3/10 and diving leading the board at 8.8/10. The water is unusually cooperative: waves hold around 0.2–0.3 m, with a representative 0.26 m at a short 3.9 seconds, and the light northeast wind averages 4 knots. That is a fine setup for a quiet harbor transit, a paddle, or a dive plan built around the slackest-looking surface conditions—though “quiet” is not the same as consequence-free. The best all-around daylight window begins after dawn at 6:15 AM and runs through the morning low tide at 8:02 AM, overlapping the 6:34–8:34 AM solunar major period. Expect the day’s sharpest wind wrinkle around 8 AM, when gusts may reach 17.3 knots, so early crews should keep an eye on exposed water and avoid treating the representative wind as a guarantee. Another useful fishing and shoreline-exploring stretch arrives around the 3:12 PM high tide, with the 1:04–2:04 PM minor solunar period providing a decent lead-in. The evening major period, 6:34–8:34 PM, follows sunset, so it is more a plan for properly equipped after-dark anglers than a casual last-minute outing. Fishing rates 7.7/10, helped by tide, solunar timing, light prevailing wind, and a falling 1020 hPa pressure trend. The water is 18.1°C, about 0.2°C below average. Chlorophyll is high at 2.53 mg/m³, but that is a water-color measure, not a promise of fish activity or underwater visibility. Atmospheric visibility is forecast near 13 km under nearly complete cloud cover; divers should not confuse that with subsurface clarity. Compared with the reconstructed CatchWindow history, today’s boating and kayaking scores remain strong, while sailing slips to 5.4/10: there is simply not much steady breeze to work with, despite the occasional gust. Diving is marginally better than yesterday’s 8.7. The next few days stay mostly dry, but seas become less settled at times, especially Thursday with 0.4–0.7 m waves and stronger wind. Best bet: launch early, use the morning tide-and-solunar overlap, and be back in before the 8 AM gusts decide to audition for a bigger forecast.
