San Francisco, CA Daily Water Report — August 24, 2026

Today's coastal conditions in San Francisco are shaping up nicely for a variety of water activities, with a definitive nod towards boating and diving. Boaters will enjoy a 7.3/10 suitability score, thanks to manageable wave heights of 0.78 meters and a gentle wind predominantly from the WSW at 8 knots. Diving enthusiasts can also expect favorable conditions, with a 7.2/10 score, supported by decent water clarity and an inviting sea surface temperature of 16.9°C. Surfing and kayaking are on the middling side today, each scoring a 6.6/10. Waves are steady at 0.78 meters with a short period swell from 283 degrees, making for consistent if not particularly thrilling conditions. Surfing might be best around 20:00 when the waves calm slightly to 0.72 meters. Kayakers should be mindful of the wind picking up to a gusty 20.6 knots by 18:00, which could make for a more challenging paddle. Fishing scores a 6.4/10, with solunar activity peaking during the major period from 09:11 to 11:11. The high chlorophyll concentration indicates a bloom, which can be a double-edged sword—potentially attracting fish but also affecting water clarity. Recent days have seen a slight improvement in conditions, particularly for boating and kayaking, which have climbed from a low of 4.2/10 to today's more favorable ratings. The rising barometric pressure, now at 1015 hPa, suggests stable weather, with no rain expected. Looking ahead, the next few days promise a gradual increase in wave activity, peaking on the 29th with swells reaching up to 1.2 meters. For those planning a trip, the best bet is to seize the calm before the stormier conditions roll in. In summary, today is a solid day for getting out on the water, especially for boaters and divers, with conditions expected to remain generally stable through the week.
