Playa Blanca - surf spot statistics

Best Surf Season (June - August)

The Southern Hemisphere winter unleashes its fury on the South Pacific, and Playa Blanca feels the brunt. During these three months, average swell heights peak near 1.8m with powerful periods consistently holding in the 12.8-12.9s range. The dominant swell trains roll in from the SW and WSW, wrapping perfectly into the west-southwest-facing beach. More importantly, the frequency of offshore winds from the east (NNE, NE, ENE) hits an annual high, with ideal wind percentages climbing to 12-13%. While still a minority, these windows often align with crisp high-pressure systems sliding across the continent, delivering clean, groomed lines. If you time it right, you can score long-period, hollow waves with minimal chop – the best of the year at this spot.

Fair Surf Season (March - May & September - November)

The shoulders of winter see a slight drop in swell consistency but still maintain a solid 1.7m average height and periods above 12.8s. Swell direction remains locked in the SW/WSW quadrant, so the beach continues to receive ample energy. However, the trade-off comes in the wind department. Ideal offshore flow drops to the 2-10% range, and the predominant onshore pattern – a relentless mix of SSW, SW, and WSW winds – degrades wave quality considerably. Expect punchy but frequently chopped-up faces during these months. The best sessions come during brief, synoptic-scale breaks when a transient high-pressure ridge stalls over the coast, offering a few hours of glassy conditions before the onshore flow returns.

Low Surf Season (December - February)

Austral summer brings the smallest average swell of the year (1.6m) and the lowest ideal wind percentages – a paltry 1% in each month. Swell direction is still dominated by SW and WSW, but the wave heights are concentrated in the 1-2m range rather than the 1.5-2.5m punch of winter. The real problem is the wind: a nearly constant stream of SSW, SW, and WSW winds funnels onshore, creating messy, lumpy conditions for the vast majority of the time. While the occasional long-period groundswell can still light things up, the onshore breeze typically ruins the party. For the dedicated surfer, early mornings offer the only real chance at clean conditions before the seabreeze kicks in.

December: Summer Onslaught Begins

December brings the return of summer patterns: average swell height drops to 1.6m, period holds at 13.1s. Swell direction splits between SW (59.1%) and WSW (37.6%), with a noticeable increase in the 1-1.5m category (20% from WSW). Wave heights in the 1.5-2.5m range still account for 52.1%, so there is decent size, but the wind ruins the party once again. Ideal offshore conditions sag back to 1%. Onshore flow from SSW (26.4%), SW (27.5%), and WSW (18.9%) dominates over 70% of the time. The SW wind frequently blows at 10-20 kph (12.3%) and even 20-30 kph (6.3%), creating messy, lumpy conditions for most of the month. The rare offshore easterly flow is virtually non-existent. December is a month for the die-hard surfer willing to deal with wind-affected waves for the chance at the occasional cleaner set. Dawn patrol offers the only real hope for a smoother surface before the seabreeze kicks in. It’s the start of the low season – enjoy the warm air, but bring your grovel board.
