Conditions are good today. Seaweed levels are low and the water is clear. No significant concerns.
San Diego sits at the southern end of California's coast, bordered by Mexico to the south. Pacific swells arrive from the northwest and west, with the Channel Islands blocking some swell energy. Water temperature is cooler than tropical destinations: typically 60–70°F.
San Diego has no Atlantic sargassum. California beaches have native kelp forests which are natural and healthy: you may see kelp washed up on shore, which is normal. The main beach considerations are wave height, rip currents, and morning marine layer (fog).
San Diego Bay was first mapped by Spanish explorer Juan Rodríguez Cabrillo in 1542, making it the site of the first European contact with the Pacific Coast of what is now the United States: the Cabrillo National Monument on Point Loma marks the spot where he landed. The Spanish established their first California mission: Mission San Diego de Alcalá: here in 1769, beginning the chain of 21 coastal missions that stretched 600 miles up California's coast, each a day's walk apart along El Camino Real. During World War II, San Diego became the largest naval base complex in the world, and the battleship USS Midway: now a museum in the harbor: is a reminder that these Pacific waters were a staging ground for some of the war's most critical campaigns.
