Spot Kontiki - surf spot statistics

Best Surf Season (February - April)

As the austral summer transitions into autumn, the South Pacific high-pressure system begins to weaken, allowing for more frequent bursts of offshore winds from the NW quadrant. March stands out as the most promising month, with ideal wind conditions occurring 18% of the time – the highest of the year. During this window, long-period SSW to SW swell dominates, with wave heights averaging 1.6-1.7m and periods around 13-14s, delivering powerful, punchy waves that break cleanly along the beach. The combination of consistent swell and occasional offshore gaps makes this the premium period for scoring clean, rippable waves at Spot Kontiki.

Fair Surf Season (January, May)

January and May offer a mixed bag. January sees a slightly lower ideal wind percentage (6%) but still benefits from a solid swell regime – average height 1.4m and period 13s – with a high proportion of SSW swell. May brings a larger average swell (1.8m) and still decent period, but onshore winds from the S and SSW pick up, limiting quality sessions to those brief moments when the wind shifts to the NW. These months are worth watching: when the stars align, you can find some fun, shoulder-high waves with enough push to get into the wave early.

Low Surf Season (June - December)

The second half of the year is a challenging stretch for Spot Kontiki. From June through December, the South Pacific Anticyclone strengthens, locking in persistent onshore flow from the S through SW quarter. Ideal wind occurrence plummets to 3-5%, and even though swell remains plentiful – heights often in the 1.6-1.9m range with long periods – the constant onshore wind texture chops up the faces and robs the waves of their form. The best chances within this low season come in late September and early October, when the first spring transitions can briefly unsettle the trade winds, offering short-lived windows of cleaner conditions. But for the most part, expect bumpy, wind-affected surf that requires a determined approach and low expectations.

February: Stepping Up, More Windows

February shows improvement. Average swell height ticks up to 1.5m and the period remains a healthy 13.1s. Swell continues to arrive predominantly from the SSW (77.3%) and SW (21.6%). The big news is that ideal offshore wind jumps to 12% of the time – the second-best month of the year. While the dominant wind directions are still SSW (28.9%) and SW (25.2%), the frequency of lighter, more variable breezes increases. Notably, wind from the SSE and SE picks up, offering more cross-shore options. When the wind does clock to the NW quadrant, the waves – already packing a punch from their long journey across the South Pacific – transform into clean, lined-up walls perfect for carving. It's a month that rewards patience and careful forecast reading.
