Foz do Lizandro - surf spot statistics

Best Surf Season (October - March)

The North Atlantic fires on all cylinders from October through March, delivering a non-stop conveyor belt of powerful, long-period groundswell. Foz do Lizandro's west-northwest orientation is perfectly positioned to capture the dominant WNW to NW swell trains that march across the Atlantic. Average wave heights range from 2.0m to 2.6m, with periods consistently in the 11-13 second range – right in the powerful, long period sweet spot. Ideal offshore winds from the western quadrant (WNW through SW) are most frequent during these months, with ideal wind percentages climbing to 20-25%. This is prime time for quality surf at Lizandro, with plenty of punchy, hollow waves on offer.

Fair Surf Season (April & September)

April and September represent transitional months. Swell activity remains respectable with averages around 2.0m and periods around 11 seconds. However, the consistency drops and the percentage of ideal offshore wind decreases to 13% in April and 12% in September. Longer breaks between swell events, combined with a more fickle wind regime, make these months less reliable than the peak season. Still, with a keen eye on the charts, you can score clean, fun-sized waves under favourable conditions.

Low Surf Season (May - August)

From May through August, the North Atlantic storm track retreats northward, causing a significant drop in swell energy. Average wave heights fall to between 1.4m and 1.7m, and periods shorten to the 8-10 second range. The dominant swell direction shifts to NNW and NW, which are still okay, but the wind becomes the main challenge. The prevailing northerly Nortada wind regime dominates, with north winds blowing at moderate to fresh speeds 30-40% of the time. These winds are cross-shore to slightly onshore at Lizandro, leading to bumpy, choppy surface conditions. Ideal offshore wind percentages plummet to 3-9% in these months. Combined with smaller swell and weaker periods, the overall surf quality is subpar. However, occasional early-morning offshore easterlies or a fleeting summer groundswell can still produce the odd session.

September: The Turn of the Tide

September marks the beginning of the transition back to autumn. Average swell height rises to 1.6m and period improves to 10.5 seconds. Swell direction is still largely north, with NW at 36.0% and NNW at 34.4%, but there is a notable increase in WNW (15.4%) and W (4.4%) as the first autumn storms begin to develop. Ideal wind percentage improves to 12% – the best since April. North winds are still common (N 34.3%, NNW 17.4%), but their intensity tends to be lighter than in summer. The return of long-period groundswell becomes more frequent as the Atlantic storm track starts to creep south. September offers some of the best transitional conditions: smaller crowds, cooler water, and the chance for clean, fun-sized waves under offshore winds. It's a month to watch the forecasts closely.
