Herradurra - surf spot statistics

Best Surf Season (December - May)

The heart of the Peruvian summer delivers a dream scenario for Herradurra. A semi-permanent subtropical high settles over the Southeast Pacific, locking in a regime of steady, light to moderate southerly winds. This is your offshore flow, grooming the long-period south swells that march relentlessly up the coast. Average wave heights hover between 1.2 and 1.5 meters with periods consistently above 12.8 seconds, wrapping nicely around the point to produce clean, rippable walls. The combination of reliable morning glass-offs and powerful, organized groundswell makes this the go-to window for consistent quality. Whether you are chasing a fun groveler on a smaller day or a solid shoulder-high set, December through May offers the highest percentage of pristine conditions.

Fair Surf Season (June - September)

Winter grips the Southern Ocean, and Herradurra feels the punch. Swell heights peak in this period, averaging 1.5 meters with a higher frequency of 1.5-2.0 meter sets – some days even flirting with the 2.0-2.5 meter range. The periods remain long (13.0-13.7 seconds), ensuring the energy wraps effectively into the northwest-facing bay. However, the wind regime becomes more volatile. The subtropical high weakens, allowing stronger southerly winds (20-30 km/h) to dominate more often. While still offshore, these stronger gusts can introduce surface chop, making the wave face less pristine than summer. Expect rougher ocean textures and an earlier onshore pick-up as ocean ridges push through. The reward is size and power; the trade-off is a drop in wind clarity. Surfers willing to weather the stronger breeze will find the biggest, most powerful waves of the year.

Low Surf Season (October - November)

Springtime in Peru is a transitional act. The Southern Ocean storm tracks begin to migrate poleward, and swell generation tapers off. Average wave heights settle back to 1.3-1.4 meters, and the period drops slightly to around 13 seconds. The wind also enters a flux, with the percentage of ideal offshore conditions dipping to 75-82% in October before improving again in November. This means more mixed-up conditions: occasional short-period windswell from the north or northwest can spoil the lineup, and the south swell windows become less consistent. It is not a dead zone – there are still good days with long-period groundswell and light offshore winds – but the reliability fades. This is the time to watch the charts closely for those fleeting windows when the Pacific lines up perfectly.

February: Consistent Summer Humidity and Long Lines

February mirrors January with remarkable consistency. Average swell height holds at 1.2 meters and the period ticks up to 13.1 seconds, signaling a slightly more organized groundswell. The swell direction tightens: 73.6% from the south-southwest and 25.7% from the southwest, ensuring a steady diet of wrapping lines. The wind is ideal 95% of the time, with a slight increase in south-southwest breezes (20.2%) that can add a touch of texture but remain offshore. The standout feature is the long period – those 13-second intervals deliver a smooth, powerful ride that is hard to beat. February offers a prolonged stretch of sunny, offshore mornings and consistently fun waves. It is a classic summer month for those who want to lock into a rhythm.
