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 early July.
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.

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.
The best week for surf at Ubatuba is the week of 16 November (score 3/5) with low crowds.
Small waves but still worth a paddle for keen surfers. Short-period wind swell: expect weak, crumbly faces. Light offshore holding the lip up. Clean rides on offer. Not enough swell to get this spot firing properly.
Heads up: jellyfish: high.

The air here is 36% cleaner than the average comparison city right now.
Somewhat cleaner than a typical city. Air quality is unlikely to affect most people.
Not a pollutant. Ozone is naturally higher at altitude and near the coast, and lower in cities where traffic exhaust breaks it down. High readings here typically indicate clean air. Can cause short-term airway irritation during intense exercise but is not linked to the long-term health risks of particulate pollution.
Additive health score: each pollutant contributes points relative to its WHO 2021 guideline and long-term health impact (PM2.5 9, NO₂ 5, O₃ 3, PM10 2, SO₂ 1 at WHO limits). Data via Open-Meteo. City markers show live readings. Red line marks the WHO guideline. Updated 03:00

Ubatuba is a sprawling coastal municipality in Sao Paulo state, Brazil, with over 70 beaches. The coastline faces east and south-east into the South Atlantic. Multiple beaches produce surfable waves, from sheltered bays to exposed points. Praia Grande and Itamambuca are the main surf beaches. Warm water, consistent swell, and tropical forest setting.

Itamambuca: powerful, open beach break. Praia Grande: more accessible. Each of the 70+ beaches has different character. Choose based on swell size and wind direction.
Rip currents at the exposed beaches. Some rocky headlands. Strong shore drift on bigger swells. The variety of beaches means there is always a safe option somewhere.
Multiple access roads to different beaches. Some require dirt-road driving. The town has full facilities. Popular holiday destination for Sao Paulo residents.
Busy during Brazilian holidays and summer weekends. The 70+ beaches provide escape routes. Weekday visits and remote beaches offer uncrowded sessions. The local community is friendly.

View Best Time to Go →Combining historical conditions with school holiday crowd pressure to find the sweet spot.
The timing score combines two signals: historical conditions quality (how good the skiing or surfing typically is in a given week, based on 5 years of weather data) and crowd pressure (how many of this destination's feeder markets have school holidays that week).
Crowd pressure is weighted by each feeder country's share of visitors. If 40% of a resort's visitors come from France and France is on holiday, that contributes 0.40 to the crowd pressure score. Crowds can reduce the timing score by up to 35%, ensuring conditions still matter most.
Scores: 5 = great conditions with low crowds (the sweet spot). 4 = great conditions with moderate crowds, or good conditions with low crowds. 3 = average. 2 = below average conditions or very crowded. 1 = poor conditions or peak holiday chaos.
