Nantucket Island, MA Daily Water Report — August 25, 2026

Today on Nantucket Island, diving holds the crown with a stellar 8.7/10, offering the best conditions for underwater explorers. With calm seas peaking at 0.62 meters early this morning and a water temperature anomaly of +1.9°C, the underwater world promises to be both inviting and intriguing. If you're looking to hit the water, now is the time to dive in before the wind picks up to a gusty 20 knots around 19:00. Boaters and anglers will find their day is a bit of a mixed bag. Boating scores a respectable 7.3/10, while fishing comes in at a solid 7/10. The tides are in your favor, with a high tide at 11:13 and another at 23:14, providing ample opportunities to navigate and find your catch. However, be mindful of the 3.6 m/s ocean current, which could make anchoring a bit tricky. Surfers might want to temper their expectations, with a 5.7/10 score reflecting the moderate wave heights of 0.6 to 0.8 meters. The swell direction from 195 degrees offers some potential, but it's not the day for epic rides. For those simply looking to kayak or sail, the scores of 6.4/10 and 6/10, respectively, suggest a decent outing, though the wind gusts will require some extra vigilance. Looking back, today's conditions are a step up from yesterday’s, especially for boating and fishing. As we move through the week, expect a slight cooling trend and increasing winds, especially by the weekend. For now, take advantage of the gentle morning waves and the inviting water temperature. To sum up, if diving is your passion, today is your day. Grab your gear and explore the depths while the conditions are prime.
