January: Summer Lull, Warm Water, Punchy Grovels

January is all about small summer surf at Itacoatiara. The average swell height sits at 3.5ft (1.1m) with a period of 9.5s - enough to keep the cove alive but short on real power. The dominant swell lines are SSE at 24.5%, S at 22.8%, SE at 20.3%, and ESE at 21.1%. The good south/south-southwest window is limited: SSW only reaches 3.0% and true SW is absent, so most waves arrive from the south-east rather than the south, making the spot less organized. The winds keep things surfable, though: ENE flows are the most frequent at 25.0%, with E at 16.2% and NE at 10.4%, so a large part of the month falls into the clean offshore/cross-offshore category, reflected in the 62% ideal wind score. Expect mostly 2-3ft (0.5-1m) peaks with a solid portion in the 3-5ft (1-1.5m) range. Water temps are a pleasant 22.3°C, air temps reach 25.6°C, and the 6.75 mm/day of summer rainfall keeps the winds variable.
