About
Boca de Santo Tomas is a rugged, exposed surfing destination in Santo Tomás Bay (Baja Norte) with a mix of beach, reef, and rivermouth breaks. The spot is known for having consistent surf, but typical wave quality is often reported as poor—performance depends heavily on perfect timing and alignment of swell, wind, and tide. Wind is a major factor. East winds are generally offshore and can help groom conditions, while onshore winds (especially Northwest) tend to degrade the lineup by adding chop. The best month noted for the spot is January, where the wind tends to be more often blown/unclean (only a portion of sessions are described as clean). Hazards are a central part of the risk picture. Expect scattered rocks, submerged/debris risk during high river flow, sharks, and strong rip currents near the rivermouth and reef sections. Shore break can also be heavy, and the overall environment is remote—plan as if you will not have assistance. For approach and timing, early sessions are emphasized before prevailing Northwest conditions build. Bigger swells can hold size well, but paddling out can become very difficult. When the rivermouth sandbar is properly formed after winter rains, surfers can sometimes get longer, more rideable sections.
