Ibiraquera seasonal overview
Best Surf Season (May - August)
As winter settles over the South Atlantic, the Southern Ocean stirs to life, sending a consistent stream of mid-period swell towards the coast of Santa Catarina. May through August marks the sweet spot for Ibiraquera, with average wave periods pushing into the 9-10 second range and wave heights holding steady around 1.3-1.4m. More importantly, the percentage of offshore wind days peaks during these months, with June seeing a remarkable 61% of the time with ideal westerly breezes. While the dominant swell direction remains from the east and southeast, it's the combination of longer period groundswell and clean offshore winds that transforms this southeast-facing beach into a rippable playground. Expect punchy, lined-up waves in the fun to solid range, with occasional bigger days when a deep low pressure system tracks far south.
Fair Surf Season (April & September)
The transitional months of April and September offer a mixed bag of conditions at Ibiraquera. April sees a nice uptick in wave period (9.0s on average) and a 49% chance of offshore wind, making it a solid shoulder month with plenty of rideable days. Swell from the SSE and S becomes more prominent, adding some variety. September, on the other hand, brings the largest average swell heights of the year (1.5m) and a healthy period (9.2s), but the offshore wind percentage drops to 36%. This means you'll have to pick your windows carefully, as the increased swell energy often comes with onshore winds that chop up the surface. When the stars align with a westerly breeze, however, September can deliver powerful, long period waves that are well worth the wait.
Low Surf Season (October - March)
From spring through summer and into early autumn, Ibiraquera experiences its low season for surf. The predominant easterly and northeasterly winds become more persistent, blowing directly onshore and degrading wave quality. Average wave periods drop to 8.0-8.5s, resulting in more windswell and shorter period chop. Offshore wind percentages are at their lowest (October 32%, November 31%, December 33%), and the swell tends to come from the east and northeast, wrapping in with less power. While occasional pulses of longer period swell can arrive from distant storms in the southern ocean, they are often accompanied by unfavorable wind directions. Summer heat and lighter winds mean small, groveling conditions are the norm, best suited for longboards or funboards. Early morning sessions before the thermal breeze picks up can offer short windows of clean, small waves.

Conditions at Ibiraquera in September
September: Spring Surge – Big Swells, Trickier Wind
September is a month of contrasts. Average swell height peaks at 1.5m – the highest of the year – and average period is 9.2s, indicating plenty of power. However, offshore wind conditions drop to 36%, making quality sessions harder to come by. Swell is dominated by ENE (18.4%) and E (20.8%) directions, with strong contributions from ESE (19.1%) and SE (15.4%). The S and SSE swells are present but less dominant. The wind patterns become more unstable as spring transitions: strong NE trades (NNE+NE = 40% of total) often blow at 10-30 kph, creating messy, wind-affected seas. The best surf comes when a cold front passes, swinging winds to the W or SW for a day or two. These windows bring clean, powerful waves that can be overhead. If you're willing to chase the forecasts, September offers some of the biggest and most exciting waves of the year, but you'll need patience and luck.
