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 May, Spot Kontiki in Peru offers consistent surf with an average swell height of 1.9m and a solid 14.5s period, indicating powerful, well-spaced waves. The swell is predominantly from the SSW and SW directions, with the majority of waves in the 1.5-2.5m range (peaking at 25.23% for SSW 1.5-2m and 16.11% for SSW 2-2.5m), providing ample energy for intermediate to advanced surfers. However, wind conditions are less favorable, with only 4% of days offering ideal offshore winds. The prevailing winds come from the S and SSE, often blowing at 10-30kph, which can create onshore choppiness. While the swell quality is high, wind interference may require patience for clean conditions. Overall, May delivers solid waves but demands selective timing for the best sessions.
