Guajataca - surf spot statistics

Best Surf Season (December - March)

The North Atlantic winter pattern brings the highest likelihood of northern swell to Guajataca, but don't expect any fireworks. Average wave heights hover around 0.7-0.8m with periods of 6.8-7.0s, offering small, rideable waves when the rare N or NNW pulse arrives. The trade-off is persistent ENE winds that blow over 30% of the time, often exceeding 20kph, creating side-onshore chop that messes up the surface. Offshore southerly winds (S, SSW, SW) occur only 11-18% of the time, so scoring clean conditions requires a perfect window between fronts. When it all comes together—a light SSW breeze and a short fetch from the north—Guajataca delivers fun, groveling waves on a longboard. This is as good as it gets here.

Fair Surf Season (April - May & October - November)

As the hurricane season approaches and departs, the trade winds ease slightly and the percentage of ideal southerly wind increases to 14-23%. However, swell energy drops as northern hemisphere storms become scarce. Wave heights settle at 0.6-0.7m with periods of 6.1-6.5s. The dominant swell shifts almost entirely to ESE and SE (80-90% of total), which wrap around the island but struggle to produce any power at this north-facing beach. Occasional E or ESE pulses can offer weak, rippable waves if the wind lays down, but it's mostly flat or gutless. Transitional months are best for low expectations and a log.

Low Surf Season (June - September)

Summer is the doldrums for Guajataca. The trade winds hammer the coast from the ENE and E, blowing over 40% of the time at moderate to strong speeds. Offshore wind drops to 8-17% frequency, and swell height bottoms out at 0.6-0.7m with periods of 6.0-6.3s. Almost 100% of the swell comes from the ESE and SE, directions that are completely blocked by the island's landmass. The rare exception is a tropical storm or hurricane tracking south of the island, which can send long-period south swell that wraps around but is often accompanied by dangerous winds and currents. For most intents and purposes, June through September is flat, choppy, and best spent on the south shore.

November: Building North, but Windy

November sees a notable increase in northern swell as winter patterns begin. NNW accounts for 2.3%, N 0.8%, and NNE 1.6%—still a small fraction. Average wave height is 0.7m with a period of 6.5s. Dominant swell remains from ESE (56.8%) and SE (13.4%). Wind picks up again: ENE (37.3%) and E (30.2%) blow hard, with ideal wind dropping to 14%. Offshore southerly totals are 3.4%. The increased north swell is tantalizing, but the persistent trade wind chop ruins most sessions. When a cold front pushes the wind to the south for a day, November can deliver the best waves of the season: clean, 1m NNW swell with punchy sections. These windows are short and sweet.
