CatchWindow fishing intelligence

Nantucket Island, MA Daily Water Report — October 6, 2026

Nantucket is a qualified go for sailing and a selective go for fishing today; for small paddle craft, it is more work than reward. The 8.7/10 sailing score leads the board, with a dry, cloud-free day, WNW wind around 11 knots and a useful breeze range through the day. But it is not a soft launch: gusts reached 24.5 knots around 6 AM, and 0.7–1.1 m seas include short-period wind waves at 3.2 seconds. That combination can make the ride brisk and lumpy even when the sky looks like it has nothing to prove. Fishing rates 7/10, helped by rising pressure near 1016 hPa, workable wind, and two strong timing overlaps. The morning major solunar period, 8:21–10:21 AM, runs across the approach to the 9:18 AM high tide; the evening major period, 8:21–10:21 PM, carries into the 9:35 PM high. The afternoon low at 2:47 PM also sits near the 2:51–3:51 PM minor period. Those are windows, not guarantees, but they are the day’s best reasons to be organized rather than merely optimistic. Boating earns 6.4/10, down from 7.5 yesterday as the wind and chop build. The ocean current is forecast near 0.89 m/s toward 87 degrees, another factor for route planning and handling around tide changes. Kayaking is only 4.1/10, a sharp decline from yesterday’s 7.2: gusty WNW wind, short waves, and current are a poor recipe for casual miles. Diving has no usable score today, so it gets no recommendation. Air temperatures only reach about 13.5 C, with a representative feels-like temperature near 6 C; marine SST is 17.2 C, so exposure management matters even under clear skies. The 26.8 km atmospheric visibility is excellent, but it says nothing about underwater visibility. Conditions ease notably Wednesday, with waves forecast at 0.3–0.7 m and peak wind near 12 knots. Thursday turns breezier again, with winds up to 22.5 knots and seas potentially reaching 1.2 m; Saturday currently looks quieter on the water. Best bet: rig for the morning tide and solunar overlap, sail with a reef-ready mindset, and leave the casual kayak plan for Wednesday.
