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.

April: The Goldilocks Month – Consistent, Clean, and Comfy

April enters prime time with an average height of 1.0m and a peak period of 14.1 seconds – the longest of the year. The southern hemisphere is absolutely cranking; 75% of all swell comes from SSW, and another 22% from S. More importantly, the 1-1.5m range makes up a healthy 30% of the spread, meaning waist-to-shoulder high waves are common. The 1.5-2m range also appears (1% of SSW), offering the occasional pumping set. Wind conditions are near-perfect: 88% ideal. Westerly to northwesterly winds dominate (WNW 21%, NW 18%, W 13%), and they are predominantly light to moderate – ideal for keeping the surface smooth. The Pacific high has established its spring position, holding the onshore flow at bay. This is the month where every swell seems to deliver, whether you want a fun longboard session on a small day or a shortboard session on a firing head-high wave.
