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.

October: Awakening Swell, Stubborn Winds

October brings a slight reduction in swell size – average height 1.8m, period 13.2s – but the quality of the swell remains high. SSW dominates at 86.6%, with a healthy 46.0% in the 1.5-2m range and 18.9% in the 2-2.5m range. The wind, however, is stubborn: ideal offshore conditions occur only 3% of the time. The wind rose shows S (36.6%) and SSW (38.6%) still in control, but a noticeable uptick in SW (16.7%) and even some WSW (1.6%) indicates the onshore flow is strengthening. Occasional spring storms can briefly disrupt the pattern, bringing wind from the north or east. These transient windows are the primary opportunity for clean surf. The waves possess plenty of power, so when the wind cooperates, the results are memorable.
