Tres Marias

Tres Marias, Rio Grande do Sul, Brazil is a lesser-known South Atlantic surf spot with a more local, natural feel than Brazil’s famous tropical breaks. In Rio Grande do Sul, the coastline is exposed to consistent swells from the South Atlantic, and Tres Marias typically offers a raw, wind-sensitive beachbreak/point-style setup depending on the exact sand and reef configuration at the time.

What it’s like

• Wave type: Often a beach break with shifting peaks; can produce clean lefts and rights on the right swell.
• Best conditions: Generally works best with south or southeast swell and light offshore or low wind.
• Skill level: Usually intermediate to advanced when it’s sizable, because Southern Brazil surf can be powerful and choppy.
• Crowds: Typically less crowded than more famous Brazilian surf destinations.
• Atmosphere: Quiet, local, and scenic, with a colder-water feel compared to northern Brazil.

What to expect

• Water temperature: Cooler than most of Brazil; a wetsuit is often needed, especially in winter.
• Consistency: Can be quite reliable when southern swells are active, but conditions can change quickly with wind.
• Hazards: Strong currents, shifting sandbanks, and heavy surf on bigger days.

Best season

• Autumn and winter in the Southern Hemisphere often bring the best swell windows, especially when South Atlantic storms send in groundswell.
