10-day surf forecast with Strike Scores for Astillero, Carazo, Nicaragua
Astillero is Nicaragua's powerful rivermouth discovery—a hollow beachbreak in a fishing village that can hold waves up to 8 feet and beyond. The river constantly replenishes the sandbars, creating hollow peaks with rights typically outperforming lefts. The wave is known for its hollow barrels, double-overhead days, and point break sections that demand experienced surfers. What makes Astillero special is the combination of quality waves and authentic Nicaragua: no crowds, warm water, a working fishing village, and perfect conditions when the swell hits. 4WD access adds to the adventure.
