Ilha dos Lobos - surf spot statistics

Ilha dos Lobos in Brazil offers varying surf conditions throughout the year, with the best months typically aligning with the Southern Hemisphere’s winter and early spring. The spot is predominantly wind swell-driven, with ground swells peaking between May and August, reaching up to 38% occurrence. During these months, the mean swell size hovers around 1.5–1.7m, providing more consistent and higher-quality waves, particularly from May to July. Wind conditions, however, are less favorable, with good winds only present around 26–28% of the time in mid-year months, though still better than the later part of the year. September onward sees a sharp decline in favorable winds, dropping to just 14%, making late-season sessions more challenging despite the decent swell persistence. Early in the year, from January to April, wind swells dominate (85–70%), but the smaller average size (1.3–1.5m) and poorer wind conditions (79–77% bad winds) limit optimal surfing windows. The best balance between swell quality and tolerable winds occurs from May to July, when ground swells are more frequent, wave height is reliable, and the chance of rideable conditions peaks despite the still-suboptimal wind stats. Surfers should target this period for the most consistent sessions, though shoulder months like April and August can also deliver decent waves, especially when wind luck aligns.

June at Ilha dos Lobos offers decent surf conditions, though not ideal. The average swell height is 1.5m with a solid 9.8s period, providing fairly well-spaced and rideable waves. The most dominant swell directions are from the south and southeast, with a significant portion of waves in the 1–2.5m range, peaking in the 1–1.5m and 1.5–2m brackets. SSE, S, and SE swells contribute the most to rideable conditions, with a good balance of power and shape. However, wind is where things get tricky—only 28% of the time is it favorable for surfing. The predominant winds come from the north and northeast, often blowing in the 10–30kph range, which can create chop or cross-shore conditions. SSW and SW winds, though less frequent, also bring mid-range speeds that may disrupt wave quality. Overall, June sees surfable waves, but wind interference limits optimal sessions to less than a third of the month. Advanced surfers can still score clean rides when winds align, but expect mixed conditions with occasional onshore disruptions.
