CatchWindow fishing intelligence

Nantucket Island, MA Daily Water Report — August 29, 2026

Today on Nantucket Island, it's a fine day for sailing and diving. With a sailing score of 8.2 and diving at 8.5, both activities are buoyed by favorable wind and wave conditions. The wind is coming from the NNW at a brisk 13 knots, with gusts reaching up to 19 knots, providing a lively sail but nothing too overwhelming for experienced hands. Meanwhile, divers will benefit from the relatively calm wave heights, peaking at just 0.82 meters, and the clear underwater visibility that often accompanies such conditions. Fishing enthusiasts should note a solid 7.3 score, though slightly down from yesterday's 7.5. The full moon, almost perfectly illuminated, is setting the stage for potentially active feeding periods, particularly during the solunar major from 12:25 to 14:25. The water temperature is a comfortable 21.2°C, marginally above average, which could keep fish a bit more active than usual. Surfers might find the conditions a bit lacking with a score of 6.6, as the wave period is short at 5.1 seconds, and the swell isn't particularly impressive. However, if you're keen on catching a wave, the late afternoon when the wind calms slightly might offer a decent window. Boaters and kayakers should be cautious, as conditions are less ideal with scores of 6.1 and 5.1, respectively. The wind and currents could make for a choppy ride, particularly in exposed areas. Wildlife watchers won't find exceptional conditions, but a score of 6.6 suggests there are still some opportunities during the solunar minor windows. Looking ahead, the weather will stay relatively stable with temperatures fluctuating between 17.6 and 25.1°C over the next few days. Winds will remain moderate, with a slight increase expected by September 3rd. For those planning a trip, Thursday is shaping up to be the best day for diving, with the calmest waves of the week forecasted.
