Zipolite - surf spot statistics

Best Surf Season (April - September)

The heart of the south swell window pulses strongest during these months as the Southern Hemisphere kicks into high gear. Powerful long-period groundswells from the deep Pacific roar toward this south-facing beach, with average wave heights consistently holding between 1.5m and 1.7m and periods often exceeding 13 seconds. The dominant swell angles from SSW and S align perfectly with Zipolite’s exposure, producing clean, peeling lines. Offshore winds from the north and northwest prevail frequently, especially from June through September when ideal wind percentages climb above 60%. This is when the spot really comes alive—expect firing, rippable surf with plenty of punch.

Fair Surf Season (October & March)

These shoulder months offer a mix of quality and quantity. October still sees robust south swell energy with average heights around 1.5m and long periods, while March begins to ramp up from the winter lull with 1.4m averages and strong SSW pulses. Wind patterns are more transitional, with ideal offshore flow around 45-60% of the time, but when conditions line up, the waves can be just as good as the peak season. Ocasionally, lingering summer or winter patterns produce windows of glassy perfection.

Low Surf Season (November - February)

During these months, the south swell machine takes a breather, and average wave heights drop to 1.2-1.3m. While still surfable, the energy is less consistent and periods shorten slightly to 11-12 seconds. The good news: offshore winds from the north and northwest are very reliable, with ideal wind percentages ranging from 53% in February to 65% in November. This means smaller but clean waves, perfect for groveling or longboarding. It’s not pumping, but it’s far from flat—when the right swell fills in, those long lines still wrap nicely into the bay.

August: Consistent Power and Clean Air

August mirrors July with a 1.6m average swell and 13.4s period, plus a 64% ideal wind score. Swell direction leans SSW (54.4%) and S (36.2%), with a notable 14.6% of SSW swells in the 1.5-2m range and 4.1% at 2-2.5m. Offshore flow remains strong from the north and east (N 8.3%, NNE 4.8%, ENE 6.2%, E 10.1%). The consistency is remarkable: day after day of shoulder-to-head-high waves with glassy faces. This is a prime month for logging or shortboarding, as the swell power is steady and the winds cooperate. The only minor drawback is the occasional tropical wave, but that typically brings added swell and manageable wind shifts.
