CatchWindow fishing intelligence

Bar Harbor, ME Daily Water Report — September 5, 2026

Sailing and diving own Saturday at Bar Harbor, with boating close behind and the surf too small to chase. A dry, partly cloudy day under a last-quarter moon, 42 percent illuminated, brings a representative north wind near 10 knots, gusting toward 20, over seas that barely move: 0.4 to 0.5 meters, with the calmest reading 0.36 meters near 04:00. That mix is why sailing scores 8.4 and diving 8.3—enough breeze and cloud for a sail without a lumpy ride, and enough quiet water and temperature signal for a dive—while surfing sits at 5.2 on short 4.3-second waves and a 0.22-meter swell from the southeast. The morning is the tradeoff. The day’s strongest gust, 22 knots, is forecast around 08:00, overlapping the first solunar major period from 06:31 to 08:31 and the hours after the 05:31 high of 2.96 meters. Fishing reaches only 6.9 from solunar timing, tide state, a rising 1010 hPa pressure, and that wind: a usable window, not a standout. Kayaking at 6.6 feels the same early gusts. Later, as wind eases toward the lighter end of the 5.7–11.6-knot range, small-craft comfort improves. The 11:34 low of 0.43 meters, with wildlife at 7.2 from solunar timing, low-tide proximity, and wind, is the shoreline look. Evening high water at 17:52 and the second major period, 18:31–20:31, run into sunset at 19:06. Against recent reconstructed scores, sailing is the clearest step up from the 5.6-to-7.2 stretch earlier in the week, while boating at 7.8 eases off yesterday’s 8.5. Diving has held in the mid-8s for days. Marine SST is 16.2 C, 1.6 C above average. Atmospheric visibility is 25.6 km; that is not underwater clarity. No rain is indicated. Sunday through Tuesday look quieter still, peak winds under 10 knots, waves mostly 0.1–0.4 meters, and little rain chance. Wednesday and Thursday bring 65 percent precipitation chances and seas building toward 0.6–1.1 meters by the 10th. Best bet: raise sail on the afternoon northerly while the water is still this small, then treat the next three days as the calmer encore before the midweek blow.
