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.

May: Best Wind, Worst Swell

May offers the highest percentage of ideal wind of any month at 23%, with southerly components (S+SSW+SW) totaling 3.7%. However, the swell is abysmal for this north-facing spot. Average wave height is 0.7m with a period of 6.1s. Northern swell is almost nonexistent—just 0.6% from N and NNW combined. Swell is almost exclusively from ESE (49.5%) and SE (44.8%), which are completely blocked. The trade winds are shifting: E (35.5%) and ENE (26.4%) still dominate, but lighter winds are more common. In practice, May offers the cleanest surface conditions, but there is almost no surf to ride. Only the occasional long-period south swell from a distant storm can wrap around, but it's rare.
