K-40 (Puerto Nuevo)

K-40 is a reef break consisting of multiple peaks that deliver both left and right-hand opportunities over submerged rocky formations. Waves can peel for extended distances and the break handles chest-high to well-overhead swells, with best shape appearing on west swells combined with easterly offshore winds during mid to high tide. The spot suits intermediate and advanced surfers willing to navigate technical conditions and hazards.

The area has been surfed since at least the 1940s when San Diego-based surfers began making excursions south of the border, with documented sessions dating to the early 1960s when the broader Ensenada region started attracting visiting surfers. The stretch of coastline surrounding K-40 became established in surf culture during the 1960s as part of the broader Baja exploration wave, though K-40 itself operates as a secondary reef among several clustered breaks in the region.

K-40 sits in Northern Baja near Puerto Nuevo, positioned among neighboring reefs including Raul's and Las Gaviotas, with the break name derived from its proximity to the K-40 highway marker. Access typically involves navigating through Puerto Nuevo, though specific parking facilities require local knowledge. The rocky, urchin-covered bottom requires water booties and demands respect for the shallow reef, particularly during low tide periods.
