Pico Alto - surf spot statistics

Pico Alto, Peru, is a world-class big-wave spot with consistent conditions year-round, but the best months for surfers—especially those seeking powerful, clean swells—fall between April and September. During this period, the mean swell size peaks at around 2.0m, with virtually no days lacking swell (99% ground swell dominance in most months). The trade-off is the wind conditions, which are overwhelmingly onshore or unfavorable (98-99% bad wind days), making clean surf sessions rare. However, when the winds do align, the waves are exceptional. The shoulder months (March, October) still offer solid swell size (1.6m-1.8m) with slightly better odds for good wind days (around 8% in March, 1-2% in October). The smallest swells occur in January and December (1.4m mean), but even then, the swell consistency remains high (96% ground swell). For surfers prioritizing size and consistency over wind conditions, June to August is prime time, though patience is required for those rare clean wind days. Conversely, if lighter winds are a priority, February and March offer marginally better chances (11% and 8% good wind days, respectively). Overall, Pico Alto delivers heavy, powerful waves year-round, with the biggest and most consistent swells in the austral winter—ideal for experienced surfers comfortable with challenging conditions.
