Spot Kontiki - surf spot statistics

Spot Kontiki in Peru offers consistent year-round surf conditions, primarily fueled by ground swells, which dominate 90% or more of the time across all months. The swell is exceptionally reliable, with virtually no days of flat conditions. The mean swell size ranges from 1.4m in January and December to 2.0m from June to August, peaking in the southern winter months with bigger, more powerful waves. However, wind conditions are often unfavorable, with onshore winds prevailing for 70% or more of the year, particularly from April to October, when bad wind days exceed 90%. The best balance of swell size and favorable winds occurs from January to March, when ground swells remain strong (1.4m-1.6m) and the likelihood of good winds rises slightly to around 20-24%. February stands out as the most promising month, offering the highest chance of clean conditions (24% good winds) alongside solid 1.5m swells. Late in the year, December also improves slightly with 9% good winds and 1.4m swells, though wave power decreases. For advanced surfers seeking bigger waves, June-August delivers consistent 2.0m swells, but the strong onshore winds make it a less ideal time unless you’re prioritizing size over shape. Overall, the early-year window provides the best compromise between swell consistency and manageable winds.

In September, Spot Kontiki in Peru offers consistent surf with an average swell height of 1.9m and a solid 14.0s period, providing powerful, well-formed waves. The swell direction is primarily SSW (53.6% occurrence for waves 1.5-2.5m) and SW (35.5% for 1.5-2.5m), delivering clean, rideable conditions with decent energy. However, wind conditions are less favorable—only 4% of the time is ideal for surfing, as prevailing winds are mostly S to SSE (often 10-30kph), which can create onshore or cross-shore chop. Expect overhead to double-overhead waves (1.5-2.5m) around 73% of the time, making it best for experienced surfers. Smaller days (1-1.5m) occur roughly 16% of the time. While the swell quality is reliable, wind interference limits pristine sessions, so dawn patrol or late afternoon sessions may offer cleaner conditions.
