San Jose Rivermouth (Baja Sur)

San José Rivermouth is a sandbar-based river-mouth surfing spot where the San José Estuary meets the Sea of Cortez. Surfing quality is closely tied to how the sandbars at the mouth are configured, so the wave can range from fun and rideable to heavily current-affected—especially when swell and river flow combine. In terms of wind, NW winds are the most favorable direction and can help clean up the face. Providers note a thermal pattern where conditions often start with lighter offshore winds in the morning and shift toward afternoon sea breezes. Overall wind reliability is described as low, so it’s important to match both wind direction and local conditions before paddling out. For swell, southern angles are preferred: SE/southerly swell directions are noted as working best, with an optimal swell-height window reported around 1.0–2.5 meters. The break is described as exposed, with a typical peely, right-hand wave. With larger southern swells, currents can increase and the wave may close out or become very heavy. Safety is a major consideration. Bacteria/pollution levels can rise after heavy rain or if the estuary recently opened/broke through, and strong rip currents are possible near the rivermouth. It’s specifically recommended to avoid surfing for 48–72 hours after heavy rain, and to check the sandbar status locally after major weather events. The lineup can be crowded on good days, so arriving early and following standard etiquette helps you manage congestion and localized behavior.
