Cape Cod, MA Daily Water Report — August 31, 2026

Today's marine conditions around Cape Cod are a mixed bag, but with some excellent opportunities, especially for divers. With a diving suitability score holding steady at 8.8/10, it’s a top pick for the day, thanks to calm seas, light winds, and clear conditions. The water temperature at 21.1°C is slightly above average, making it comfortable for extended underwater exploration. Boaters will find a decent window today with a score of 7/10. The wind is mild, coming from the NNW at 4 knots with gusts up to 8 knots, which keeps the waters manageable. The calmest period is around 2 PM when wave heights drop to 0.3m. However, be mindful of the ocean current moving at 2 m/s toward 243 degrees, which could affect smaller vessels. Fishing scores a 6.9/10, a slight dip from recent days, but still respectable. The solunar major period from 1:56 to 3:56 PM coincides nicely with the afternoon high tide, likely enhancing your chances. The morning's negative low tide might make for tricky conditions, so plan accordingly. Surfing, on the other hand, is not at its peak with a 5/10 score, thanks to a modest swell of 0.4m at 3.6 seconds. If you’re determined, aim for the early afternoon when conditions are at their calmest. Looking ahead, the next few days bring varied conditions, with potential rain and stronger winds on the horizon, particularly on September 1st and 3rd. The weekend promises lighter winds and minimal rain chances, making it potentially more favorable for all activities. In summary, if you’re headed out today, diving is your best bet, with conditions ripe for an underwater adventure.
