K-38 is a classic Baja beach break named for its kilometer marker on the toll road south of Tijuana. The spot delivers consistent peaks and occasional barrels when winter NW swells push through, making it a reliable option for surfers heading south of the border.

Frequently Asked Questions

What tide is best at K-38?

What wind direction is offshore at K-38?
