New Bedford Harbor, MA Daily Water Report — August 27, 2026

Diving is your clear winner in New Bedford Harbor today, with the best conditions you'll see all week. A south-southeast breeze has kicked up compared to the glassy mornings earlier this week, but for anyone heading underwater, that 23.2°C surface temperature and manageable chop still earn an 8.8 out of 10. The harbor is running 1.2°C warmer than average for late August, with a short-period wind wave of 0.3 meters on top of a 0.28-meter swell from the southwest. That combination keeps the surface active but won't punish a diver with surge. Boating and sailing both look solid, though not the standout windows we saw in the past few days. The 8-knot breeze with gusts into the mid-teens will fill sails nicely and keep a powerboat on plane without much fuss. Waves top out around 0.6 meters this afternoon, but the morning offers your calmest ride shortly after dawn when seas drop to 0.26 meters. That's a meaningful window for anyone wanting a smooth run before the sea breeze builds. Fishing scores 6.9, which is actually a slight improvement over yesterday's 7.2—the waxing gibbous moon and solunar push around mid-morning and late evening help offset the moderate wind. Chlorophyll readings are elevated, but that's a water-color note, not a fish guarantee. Kayaking and surfing are more marginal today. The 5.4 for paddling reflects that building afternoon wind and short, bumpy chop—fine for a quick morning lap, but not the flat-water conditions we had last week when scores routinely hit the high 7s. Surfers will find the swell direction acceptable from 200 degrees, but the wave period barely stretches past three seconds, delivering weak, crumbly energy at best. Looking ahead, Friday brings lighter wind and smaller seas, with peak gusts under 10 knots and wave heights dropping into the 0.3 to 0.4-meter range—that will restore the butter-smooth conditions for boaters and paddlers. Saturday sees a bump in wind again, but Sunday calms back down before a more unsettled pattern arrives early next week. Best bet: get on the water before 10 a.m. while the harbor is still flat and the solunar bite window is open.
