CatchWindow fishing intelligence

San Francisco, CA Daily Water Report — August 22, 2026

Today in San Francisco, the water activities are a mixed bag, but sailors, rejoice! With a stellar sailing score of 9.2/10, the conditions are nearly perfect for hitting the bay. The steady westerly winds at 12 knots, gusting to nearly 20, provide the ideal push for a thrilling sail. Just keep an eye on those gusts peaking around 6 PM. Surfers also have something to celebrate with a decent score of 7.1/10. The waves, reaching up to 1.1 meters with a 7-second period, should offer some fun rides, particularly in the morning when the wind is lighter. However, the very high chlorophyll levels signal bloom conditions, which might impact water clarity and your post-surf rinse-off. Fishing and boating are slightly less favorable, scoring 6/10 and 6.4/10 respectively. Anglers should target the major solunar periods in the early morning and evening for the best chance of a catch, despite the lack of tide data today. Boaters should be cautious of the ocean currents moving at 0.8 m/s toward 45 degrees, which could make navigation a bit tricky. Kayakers face a tougher day with a low score of 4.4/10. The combination of moderate winds and wave activity might make for a challenging paddle. Diving conditions are decent, scoring 6.9/10, but divers should be prepared for less than ideal underwater visibility due to the high chlorophyll levels. Looking ahead, the weather remains stable with a slight cooling trend and decreasing winds through the week. The wave heights are expected to stay manageable, making for a pleasant weekend on the water. If you're looking to make the most of today's conditions, grab your sailboat and hit the water for a breezy afternoon glide.
