Del Mar Rivermouth

Del Mar Rivermouth is an exposed beach/river-mouth surfing area between Del Mar and Solana Beach. The spot is characterized by shifting sandbar formations driven by the San Dieguito River mouth, so wave shapes and peak locations can change noticeably with river flow and post-storm seabed rearrangement. Surf consistency is generally described as inconsistent, with one guide emphasizing winter as the best overall season and highlighting January in particular. East winds are repeatedly identified as the best direction for surfing here, helping produce cleaner/offshore conditions; sources also note that when conditions shift away from east flow, chop and less favorable wave character become more likely. Safety is a major focus at this location: the river mouth is associated with strong rip currents and a heightened risk of water pollution and bacteria after rainfall. Local guidance advises avoiding water contact for 72 hours after heavy rain because of significant runoff into the lineup. Submerged cobblestones/rocks and shifting sandbars add additional hazard, and crowds can build due to the easy access and dog-friendly beach areas. At the session level, sources describe typically short, punchy rides (about tens of meters) and mixed wave shapes. The working swell window is often described in the 2–4 ft range, and an optimal tide is referenced as mid tide; on very large swells, conditions can become heavy and disorganized, and sandbars may close out.
