Costa Azul - surf spot statistics

Best Surf Season (April - July)

As the Northern Hemisphere spring sets in, Costa Azul hits its prime. The Pacific high tightens its grip, ushering in consistent offshore breezes from the west to northwest—perfect for grooming the predominant south swell that travels thousands of miles from the Southern Ocean. Average wave heights climb to a fun 1.0-1.2m, while periods hover in the powerful 13-14 second range, yielding punchy, well-shaped waves that reel down the beach. This is the sweet spot where swell size, wind quality, and water temps align for peak surfability.

Fair Surf Season (March, August - October)

The shoulder months still offer plenty of waves, but conditions become more variable. March sees a rise in long-period swell as the South Pacific gears up, but winds can be a tick more inconsistent. Late summer into early fall (Aug-Oct) holds onto solid south swell energy (1.1-1.2m averages) but the trade wind influence begins to creep in, decreasing the percentage of offshore wind days. You'll still score clean sessions, especially in August, but expect more mixed conditions with occasional onshore slop.

Low Surf Season (November - February)

Winter brings a shift in the swell window. While the Southern Hemisphere is still active, the dominant storm tracks weaken, and the average swell height drops to 0.8m. More importantly, the region becomes susceptible to northerly swell from mid-latitude fronts, which doesn't wrap as efficiently into the east-southeast facing beach. Wind patterns are less reliable, with the percentage of ideal offshore wind falling to 69-73%. The result: smaller, less consistent surf with a higher chance of onshore wind ruining the session. However, when a solid south swell sneaks in under a high-pressure ridge, the few days of fun-sized, groomed waves make it worthwhile.

January: South Swell Steady, Winds Play Nice

January marks the heart of the winter season at Costa Azul, but it's far from flat. The average swell height sits at 0.8m with a period of 11.9 seconds – solidly in the 'fun-sized' and 'punchy' categories. Swell direction is heavily dominated by the south, with 33% from S and 34% from SSW, mostly in the 0.5-1m range. A notable secondary component comes from the north and north-northeast (11% combined), which can bring some inconsistent smaller waves. The wind is favorable 70% of the time, with the strongest signals coming from the northwest (11%), west-northwest (10%), and north (12%) – all of which are either offshore or side-offshore for this east-southeast facing beach. The best windows will arrive when a strong Southern Ocean low pushes long-period energy northward, wedged between a retreating low and a building high offshore. Score a session under clear skies with a light WNW breeze, and you'll find waist-to-chest high waves with clean faces.
