CatchWindow fishing intelligence

Boston, MA Daily Water Report — August 26, 2026

Today in Boston, the waters are calling all boaters and kayakers, with excellent conditions on offer. Boating scores a stellar 9.1/10, rivaling yesterday's near-perfect conditions, while kayaking isn't far behind at 8.5/10. The sea is calm, with waves gently rolling at around 0.26 meters and a mild swell from the east. The wind is a gentle whisper, peaking at just 9.5 knots later in the afternoon, so you'll enjoy smooth sailing and paddling for most of the day. Diving enthusiasts will find conditions favorable as well, with a solid 7.6/10 score. The water temperature is a pleasant 20.2°C, slightly warmer than usual, making for comfortable dives. However, be mindful of the very high chlorophyll levels, signaling a significant bloom that could impact visibility underwater. Fishing is slightly above average today, scoring 6.9/10. The best catch times align with the solunar major periods from 9:16 to 11:16 AM and again in the evening from 9:16 to 11:16 PM. The waxing gibbous moon promises some action, but the high chlorophyll could be a mixed blessing for clarity. Surfers, while the waves are small, today's conditions are a marked improvement from the past few days, climbing to a 6.4/10. The steady period and mild swell provide some fun, manageable rides for longboarders looking to enjoy the sunny weather. Looking ahead, tomorrow brings slightly higher winds, but the conditions remain favorable for most activities. Expect a gradual increase in wave height over the next few days, peaking at 0.5 meters. Your best bet today? Set sail or grab a paddle and enjoy the calm, inviting waters while they last.
