CatchWindow fishing intelligence

Portland, ME Daily Water Report — August 29, 2026

Today in Portland, ME, boating takes the top spot with an impressive suitability score of 8.4 out of 10. The calm seas and a gentle northwesterly breeze make this a prime day for getting out on the water. Winds are mild, peaking at just under 10 knots, and the waves are comfortably low, hovering around 0.5 meters, which should make for a smooth ride. The early morning calm around 8:00 AM offers the best window for those seeking the quietest conditions. For anglers, a solid 7/10 score suggests a decent day of fishing, particularly during the solunar major period from 12:26 to 14:26. The full moon overhead might stir up some activity, although the very high chlorophyll levels indicate a significant bloom, which could complicate visibility and affect fish behavior. Surfers might find the day less thrilling, scoring a 5.6/10 due to the modest wave height and short period swell. It's a step down from yesterday's 6.2/10, so perhaps it's best to enjoy the surf as a mellow paddle rather than expecting epic rides. Diving conditions are quite favorable with a 7.6/10 score. The water's a bit cooler at 17.4°C, but clarity is likely good given the low wind and wave conditions. Just watch out for the ocean current moving at 0.6 m/s towards the northwest. Looking ahead, the next few days promise mild weather with a slight uptick in wave activity expected by September 2nd. If you’re planning a seaside adventure, today’s tranquil conditions might just be the best bet for a relaxing outing on the water.
