About Ubatuba
Ubatuba is a sprawling coastal municipality in the state of S-o Paulo, Brazil, containing numerous high-quality beach breaks, with Praia Grande being a central hub. The bathymetric profile relies on shifting silica sandbanks that are heavily influenced by the steep, jungle-covered mountains plunging directly into the ocean. Because the coastline is highly exposed, it acts as a primary receptor for powerful south-easterly Atlantic groundswells. A north-westerly wind blowing off the Serra do Mar provides optimal offshore conditions, grooming the massive faces and holding open the barrel sections. The wave breaks with significant hydraulic force, delivering steep, critical take-offs that transition immediately into high-speed, plunging lips. Because the energy is concentrated heavily onto the shallow sand, it creates aggressive rip currents. The sheer power and consistency of the waves make it a premier destination. Due to the fast-paced nature of the breaks, Ubatuba is best suited for intermediate to advanced surfers possessing solid physical endurance.

How often is this page updated?
Current conditions refresh every 6 hours when the cron runs. Hourly data updates every 30 minutes. The 7-day forecast, luck factor, and packing notes are all pre-computed at the same time.
What is the luck factor?
We compare the 7-day forecast to the last 5 years of marine data for the same week at Ubatuba. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical late April.
How is 'best session' picked?
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.
Where does the data come from?
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).
Does the score capture local knowledge?
Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
