Nantucket Island, MA Daily Water Report — August 26, 2026

Today, Nantucket Island is offering a mixed bag for water enthusiasts. Divers will find near-perfect conditions with an impressive 8.7/10 score, thanks to the calm wave heights and clear skies. For anglers, it's a solid day too, with a fishing score of 8/10. The solunar major period from 9:13 to 11:13 AM aligns nicely with the incoming high tide at 11:55, making this morning a prime window for casting lines. Boaters can expect a decent outing with a 7.1/10 score. The gentle WNW winds at 5 knots will keep things relatively smooth, especially around midday when wave heights dip to a calm 0.56 meters. However, keep an eye on the ocean currents, which are moving at a brisk 3.1 m/s toward the northeast. This could be a bit challenging for kayakers, who are looking at a more modest 6/10 score today. Surfers might want to temper their expectations, as the 5.8/10 rating suggests a less thrilling ride. The swell is a mild 0.32 meters from the southwest, and the short period of under 4 seconds won’t provide much push. The water temperature is a comfortable 21.4°C, slightly above the seasonal norm, so at least you’ll be warm while waiting for the next set. Looking ahead, the next few days bring increasing winds and a higher chance of precipitation, especially by the weekend. Thursday remains relatively calm, but by Friday, gusts could reach over 14 knots, with Saturday promising even more bluster. For those planning a weekend on the water, Friday might be your last chance for a gentler sail. Best bet? Grab your scuba gear and explore the underwater world today—visibility is excellent, and the conditions are just right for a memorable dive.
