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.

December at Spot Kontiki, Peru delivers consistent surf with an average swell height of 1.4m and a strong 13.4s period, indicating powerful, well-spaced waves. The swell direction is predominantly from the SSW (30.25% of waves in the 1-1.5m range) and SW (26.84% in 1-1.5m), providing clean, rideable walls with good shape. Roughly 30% of days see waves over 1.5m, offering occasional larger sets for advanced surfers. Wind conditions are less ideal, with only 9% of days having favorable offshore winds. The prevailing winds are S to SSE (34.16% at 10-20kph, 12.56% SSE at 10-20kph), often creating onshore chop, though lighter morning winds may provide cleaner sessions. Expect a mix of mid-sized, high-quality SSW/SW swells paired with moderate onshore winds—best suited for intermediate to advanced surfers who can time sessions around wind shifts or dawn patrols. While not a wind-sensitive spot due to its exposure, the strong swell energy ensures rideable waves most days, albeit with occasional texture.
