Teahupoo - surf spot statistics

Best Surf Season (October - March)

The South Pacific stirs to life during the austral spring and summer, delivering a consistent diet of long-period groundswells from the south and southwest. With the trade wind belt shifting northward, Teahupoo sees a higher frequency of offshore flows from the north through east-northeast—perfect for grooming the iconic left. Average swell heights hover around 1.8-2.1m, with periods often exceeding 12 seconds, producing powerful, barreling waves. This window, from October through March, combines the most reliable swell with the best chance of clean conditions.

Fair Surf Season (April - May & September)

As autumn sets in, the swell machine remains active but the trade winds begin to strengthen, reducing the percentage of clean, offshore days. April still offers excellent swell size and direction, with average heights near 2.1m and periods near 12.7s, but the easterly trades pick up, making for more wind-affected surf. May and September see a further drop in ideal wind frequency (30% and 24% respectively), yet the swell remains solid. These months are a gamble, but when the wind aligns, the waves can be world-class.

Low Surf Season (June - August)

Winter in the Southern Hemisphere means the South Pacific storm tracks are at their peak, generating the largest average swell heights—up to 2.3m. However, this is also when the southeast trade winds are strongest and most persistent, blowing directly onshore at Teahupoo. Ideal offshore wind frequencies plummet to just 22-24%, leaving many days with bumpy, blown-out conditions. While the swell is massive and powerful, the window for clean surf is narrow. Only the most patient surfers willing to wait for brief lulls or north wind events will find the silver lining.

July: Mid-Winter Grind

July continues the winter pattern with average swell heights holding at 2.3m and periods around 12.1 seconds. Swell direction is very similar to June, with S and SSW swells dominating. The offshore wind frequency drops to its annual low of 22%, meaning three out of four days are blown out by strong southeast trades. This is the most challenging month for finding clean surf at Teahupoo. When the wind does go offshore, typically from the north or northwest, the waves are incredibly heavy and hollow, rewarding those who wait. This is not the month for a casual surf trip; it's for the hardcore charger willing to sit through wind and wait for the magic intervals.
