Cerro Azul - surf spot statistics

Cerro Azul, Peru, offers consistent surf conditions year-round with a strong dominance of ground swells, which account for over 90% of the swell activity in every month. The best months for surfing are typically from December through April, when the combination of swell consistency, size, and favorable wind conditions is most reliable. During this period, the mean swell size ranges from 1.3m to 1.4m, providing manageable yet powerful waves. Additionally, the percentage of good wind conditions is highest, peaking at 74% in January and gradually decreasing to 70% by March. Wind quality remains decent in April (58%) but starts to decline notably from May onward. From May through September, the swell size increases slightly to around 1.7m, but the wind conditions deteriorate significantly, with bad winds occurring more than 50% of the time. July, August, and September see the worst wind conditions, with only about 38% of days being favorable. While the waves remain sizable and mostly ground-swell-driven during these months, onshore or unfavorable winds frequently disrupt clean surf. Conditions begin improving again in October, with good wind percentages rising to 47%, and by November, they reach 56%, making late-year surfing more appealing. December marks a return to highly favorable conditions, with 63% good winds and a slightly smaller, more manageable swell at 1.3m. Overall, the prime window for surfing Cerro Azul is the Southern Hemisphere summer (December to March), when wind and swell align best for high-quality sessions.

August at Cerro Azul offers consistent surf with an average swell height of 1.7m and a solid 13.9s period, indicating powerful, well-spaced waves—ideal for experienced surfers. The swell predominantly arrives from the SW (65.9% of waves between 1–2.5m), delivering clean, organized lines with occasional overhead sets (2.5m+). Wind conditions are a mix, with 37% of days providing favorable offshore or light cross-shore winds, primarily from the S to SSW in the 10–30kph range. However, strong onshore winds (20–40kph) from the S/SSE/SE can occasionally disrupt conditions, particularly later in the month. Expect a balance of clean morning sessions and choppier afternoons. For advanced surfers, mid-month tends to be prime with higher consistency in swell and lighter winds. Pack a step-up board for bigger days.
