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.
