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.

May: Winter Swell Begins

May sees the average swell height push to 2.2m, driven by strengthening winter storm activity in the Southern Ocean. The dominant swell directions are SSE, S, and SSW, delivering long-period groundswells that shoal dramatically over Teahupoo's reef. Unfortunately, the trade winds also intensify, reducing the ideal offshore wind window to just 30%. Many days will see clean, peeling waves in the morning before the easterly trades kick in and chop up the faces. Patience is key—wait for the brief windows of northerly flow that often precede approaching fronts. When it all comes together, May can deliver some of the heaviest, most perfect barrels of the year.
