Crash Boat - surf spot statistics

Best Surf Season (December - March)

The North Atlantic winter pattern drives the most consistent swell energy toward Puerto Rico, and Crash Boat sees its highest average wave heights (1.5–1.6m) and longest periods (9.8–10s) during these months. However, the dominant swell direction is from the NE to ENE quadrant — almost directly opposite the beach's WSW exposure. This means the vast majority of waves are not well-aligned, resulting in short-period, often messy windswell that struggles to wrap in with any quality. The trade winds blow offshore from the E-ENE over 40% of the time, providing clean faces, but the wave shape remains poor due to the misaligned swell. The rare intrusion of a more westerly component can produce a decent day, but statistically those are very slim. Think of it as a lot of energy with little reward.

Fair Surf Season (April, October, November)

As the seasons transition, average swell heights drop to between 1.1 and 1.5m, and periods hover around 9–10s. The NE-ENE swell direction still dominates, but there's a slight uptick in variability, with occasional pulses from the N and NNE that can wrap into the cove. Wind conditions remain favourable, with offshore winds from the ENE-E quadrant occurring 53–66% of the time. April and October in particular see ideal wind percentages, but the waves still lack the size and alignment for truly great surf. It's a shoulder season where you can find clean, rideable waves if you're patient, but don't expect power.

Low Surf Season (May - September)

Summer brings a dramatic drop in swell energy. Average wave heights fall to 1.0–1.1m, and periods shorten to a dismal 6.7–8.7s, indicative of purely local windswell. The swell direction remains locked in from the ENE and E, producing weak, short-period waves that barely break with any form. While the trade winds still blow offshore 51–67% of the time, the lack of consistent swell makes for mostly groveling conditions. Occasional afternoon sea breezes from the SW can further degrade quality. This is the true low season for surf at Crash Boat, best reserved for longboard or SUP sessions when the ocean is otherwise flat.

November: Building Swell, Persistent Trade Winds

November delivers a bump in average swell height to 1.5m with period holding at 10.0s. The NE quadrant dominates at 42.4%, with NNE (27.8%) and ENE (16.3%) still prevalent. The trade winds remain strong: ENE (41.9%) and E (20.3%) account for the majority, but ideal wind percentage drops to 48% as stronger winds and more variable directions appear. The swell energy is building, but the direction problem persists. However, the 1.5–2.5m range grows (13% of waves), and the longer period means more power. When the wind aligns, these waves can be heavy and pumping, even if not perfectly lined up. November is a month of raw power with a chance of quality.
