Woods Hole, MA Daily Water Report — August 28, 2026

If you’re looking for the best use of the water today, make it a diving or boating day. Diving earns the top suitability score of 8.7 out of 10, and boating isn’t far behind at 7.2. The conditions support both nicely, though for different reasons. The water is warm, with sea surface temperature holding at 22.1°C, a degree above the long-term average for late August. Winds are light out of the southeast, representative around 4 knots with gusts only reaching 6, and the day’s peak shouldn’t exceed 9 knots until well after dark. That keeps the surface smooth. Wave heights average just 0.6 meters from a short-period south swell, and the calmest stretch arrives near 23:00, but through the afternoon and evening you’re looking at consistent, manageable water. For divers, the combination of mild wind, low wave action, and that warm surface layer is ideal. Visibility isn’t measured directly here, but the lack of wind-driven chop and recent stability in the marine conditions suggest decent clarity for a coastal site. Water temperature this warm means you can spend extended time on the bottom without heavy gear. The outgoing tide this morning and the incoming this evening offer the best exchange, though the tide range is modest—just over half a meter—so currents won’t be ripping. Fishing scores 6.7, which is solid but not exceptional, and that’s largely due to the midday solunar minor period coinciding with a low slack tide and a full moon overhead. The rising barometer at 1016 hPa and climbing is a classic signal that fish may feed conservatively as pressure builds. The chlorophyll reading is elevated, but that’s a water-quality marker, not a guarantee of baitfish activity, so resist reading too much into it. Surfing sits at 5.6, and while the waves are rideable, the short 4.5-second period means they’ll be crumbly and lack push. Kayakers get a 6.4, which is workable but not ideal—the protected inshore areas will be fine, but open crossings will feel the light SE breeze building through the afternoon. Compared with the past week, today’s diving score is essentially identical to the string of 8.8s we’ve seen since August 22, meaning the underwater conditions have been consistently excellent. Boating is a tick below last week’s 7.8 peak, but better than yesterday’s stiffer wind knocked it down to 5.8. Looking ahead, Friday keeps the light wind and adds slightly smaller waves, with swell dropping into the 0.3-0.5 meter range. Saturday through Monday sees a gradual increase in both wind and precipitation chances, with the highest rain probability hitting 41% by Tuesday. The pattern remains changeable but not threatening. Best bet: Slip in before lunch for a dive on the rising tide, and you’ll find the warmest, calmest water Woods Hole has offered in weeks.
