Ibiraquera - surf spot statistics

The best months for surfing at Ibiraquera, Brazil, are generally from May to September, when the swell conditions are most favorable. During this period, the ground swell percentage increases significantly, peaking in May and June at around 42%, providing more consistent and higher-quality waves. The mean swell size also remains solid, averaging between 1.6m and 1.9m, with September offering the largest waves at 1.9m. These months also see a higher proportion of good wind conditions, particularly from May to July, when around 22-25% of days have favorable offshore or light winds, reducing the impact of choppy surf. However, wind conditions deteriorate from August onward, with September and October having the highest percentage of bad winds (87%), which can affect wave quality. Outside this peak season, the swell is predominantly wind-driven, with smaller average sizes and fewer clean days. December through March sees lower ground swell influence (16-28%) and frequent onshore winds (77-85% bad conditions), making these months less reliable for optimal surfing. For the best balance of consistent swell and manageable winds, surfers should target May through July, with the understanding that wind conditions become increasingly challenging as the season progresses. Late-season swells in September can still produce excellent waves, but the likelihood of strong onshore winds rises significantly.
