Nantucket Island, MA Daily Water Report — September 3, 2026

Today on Nantucket Island, diving is the star of the show with a stellar score of 8.6/10. If you're ready to explore the underwater world, the conditions are prime. With waves peaking at a manageable 1.0 meter and the water temperature hovering around 20.1°C, visibility should be decent, although the 100% cloud cover might make it a little gloomy topside. For those on the surface, the day presents a mixed bag. Surfing gets a respectable 6.6/10, with swells coming in at 0.46 meters from the southeast. Surfers can expect a decent session, especially later in the day as the wind eases. Boaters and kayakers face a bit more challenge with scores of 6.1 and 5.5 respectively, thanks to gusty southeast winds reaching up to 18.5 knots by mid-morning. The ocean current is also brisk, moving at 2.7 meters per second, which may require some extra muscle power. Fishing enthusiasts should target the solunar major periods around dawn and dusk for the best catch, though the score holds steady at 6.1/10. The high chlorophyll levels could hint at productive waters, but remember, that's no guarantee of fish on the line. The wildlife score is a solid 7.8/10, so keep an eye out for marine life, especially during the low tide just before midnight. Looking ahead, the weather takes a turn with increasing winds peaking at 24.3 knots by the 6th. If you're planning any water activities, it might be wise to get them in before then. For now, if diving's your thing, suit up and dive in—it's the best bet for a memorable day on the water.
