Understanding California Tides

The California coastline experiences some of the most dramatic tidal changes on the West Coast. Understanding these patterns is essential for beachgoers, surfers, and marine enthusiasts.

What Causes Tides?

Tides are primarily caused by the gravitational pull of the moon and sun on Earth's oceans.

The Moon's Influence

The moon is the primary driver of tides, creating what we call lunar tides. Because the moon is much closer to Earth than the sun, its gravitational effect on our oceans is more than twice as strong.

The Sun's Role

While the sun is much larger than the moon, its greater distance means it contributes about 46% of the tidal force. When the sun and moon align (during new and full moons), we get spring tides with higher highs and lower lows.

California's Unique Tidal Patterns

California experiences mixed semidiurnal tides, meaning we typically see two high tides and two low tides per day, but they're often of different heights.
