CatchWindow fishing intelligence

Conimicut Light, RI Daily Water Report — October 4, 2026

Conimicut Light gets a firm green light for low-profile water time today: boating, kayaking, and diving all rate 8.3–8.4/10, with only sailing held back by a shortage of useful breeze rather than any rough-water problem. The sea is almost comically tame, holding near 0.1 m all day, with a small 0.1 m southeast swell at 4.3 seconds and negligible wind chop. That is excellent news for small craft handling and surface comfort, but sailors should not expect much drive from an ENE wind generally ranging 2.4–8.1 knots. The most productive all-around stretch is dawn through midmorning. First light begins at 6:17 AM, the low tide arrives at 7:39 AM, and the morning solunar major period runs 6:36–8:36 AM. Fishing earns a solid 7.6/10 on the combined timing, tide, light wind, and pressure picture. The pressure is high at 1020 hPa but falling, so it is worth treating the early window as the cleaner play rather than waiting for the day to sort itself out. The afternoon high at 3:12 PM offers another useful water-level change, while the evening major period, 6:36–8:36 PM, overlaps the final light before sunset at 6:25 PM. Cloud cover is complete, temperatures run from a cool 8.9 C to 19.0 C, and a brief rain window is forecast around 9–10 PM. Atmospheric visibility is forecast near 16.5 km, but that should not be mistaken for underwater visibility. Marine SST is 18.4 C, slightly above average by 0.2 C; divers still need to dress for a cool October session, even with the calm surface. Compared with the recent CatchWindow run, diving remains consistently strong, while boating eases slightly from yesterday’s 8.9/10. Fishing improves notably from yesterday’s 6.2/10, and sailing slips from 7.4/10 as the breeze softens. The next few days stay generally small-water friendly, though Monday’s peak wind may reach 16.4 knots before easing through the week; waves are forecast to remain only 0.0–0.4 m. Best bet: launch near dawn, work the low-tide turn through the morning solunar window, and enjoy a sea that has apparently misplaced its attitude.
