Puerto Sandino is a consistent surf spot with reliable ground swells throughout the year, making it a solid choice for surfers. The best months for surfing are from March to September when ground swell dominance is near or at 100%, and mean swell size ranges from 1.0 to 1.3 meters—offering ideal conditions for intermediate to advanced surfers. March through May provides slightly smaller but cleaner waves (1.0–1.2m), while June to September sees slightly larger swells (1.2–1.3m), though wind conditions are less favorable during this period, with only about 33–38% of days having good offshore winds. The most balanced conditions occur in October and November; October still offers solid swell size (1.2m) with improving wind conditions (43% good winds), and November stands out as the best month overall—good swell size (1.0m), a high 55% chance of favorable winds, and minimal wind swell interference. December through February remains surfable but with smaller waves (0.8–0.9m) and fewer clean wind days, making it less ideal for high-performance surfing. Overall, advanced surfers will appreciate the consistency of Puerto Sandino, with peak conditions centered around the mid-year months for size and late-year months for cleaner wind conditions.
