Itacoatiara seasonal overview
Itacoatiara in Brazil offers varied surf conditions throughout the year, with the best months generally aligning with the Southern Hemisphere’s winter and spring seasons. The swell consistency and quality improve from April to September, peaking between May and July. During these months, ground swell dominates (52-58% of the time), providing cleaner, more organized waves compared to wind swell, which is less favorable. The average swell height also increases to 1.3-1.4m, offering more powerful and rideable waves. Wind conditions are most favorable from January to June, with good wind days occurring over 50% of the time, though September through November sees a drop in favorable winds (41-44% good wind days). The worst months for surfing are typically October to December due to higher wind swell influence (66-67%) and deteriorating wind conditions, despite decent swell heights. Overall, the prime window for surfers is May to July, when ground swells are predominant, wave heights are reliable, and wind conditions remain relatively favorable. Early season (April) and late season (August) can still deliver good sessions but with slightly more variability in swell and wind. If you prioritize quality over consistency, target the mid-year months for the best experience at Itacoatiara.
