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 October, Spot Kontiki in Peru offers consistent surf conditions with an average swell height of 1.8m and a strong mean period of 14.2s, indicating powerful, well-formed waves. The swell predominantly arrives from the SSW and SW directions, with the majority of waves falling in the 1-2.5m range (over 70% combined), making it ideal for intermediate to advanced surfers. The most common swell heights are 1.5-2m (27.65% SSW, 22.14% SW), providing long, clean lines. Wind conditions, however, are less favorable, with only 6% of the time offering ideal offshore or light cross-shore winds for surfing. The dominant wind direction is southerly (S, SSE, SSW), often blowing at 10-30kph, which can create choppy or onshore conditions. While the swell reliably delivers quality waves, wind interference may require patience to score the best sessions—early mornings or occasional wind shifts could provide cleaner conditions. Overall, October is a solid month for surf here, but wind management is key.
