La Selva - surf spot statistics

Best Surf Season (October - March)

The North Pacific winter pattern fuels our most consistent swell window, with average heights hovering around 1.5m to 1.6m and periods in the 8.5 to 9.1 second range. During these months, we see the highest percentage of swell from the N, NNE, and NNW quadrants, which are the lifeblood of this north-facing beach. While ENE still dominates the swell direction at times, the winter storms also deliver a solid mix of more favorable angles. Wind is the wildcard: offshore flow from the S, SSW, and SW is still rare, but when a frontal system or a low-pressure trough sets up a southwesterly pattern, it can turn an average day into a session to remember. October and March stand out with higher percentages of ideal wind (46% and 33% respectively), making them the pick of the season.

Fair Surf Season (April - June)

As spring takes hold, the average swell height drops to 1.2m - 1.4m and the period shortens to 7-8 seconds. The dominant swell direction shifts almost entirely to ENE and E, which are less optimal for La Selva's north exposure. Wave heights are often in the fun-sized 0.5-1.5m range, decent for groveling on a log or a fish. The good news is that the percentage of ideal wind climbs significantly, peaking at 51% in May. This means cleaner conditions more often, even if the swell lacks power. This is the season for small-wave enthusiasts to take advantage of glassy mornings and light offshore breezes from the south.

Low Surf Season (July - September)

Summer brings the lowest energy of the year, with average swell heights of 1.1-1.2m and periods often below 7 seconds. Swell direction is overwhelmingly from the E and ENE, offering little to no wave of quality for a north-facing beach. The wave heights are predominantly in the waist-to-chest high range, and the short periods leave the ocean feeling weak and unorganized. Wind is mixed: July has only 25% ideal wind, while September sees a nice bump to 44%, but the swell remains too small to really excite. Occasional pulses of longer-period NW energy can sneak in from summer typhoons or distant gales, but they are few and far between. If you're not picky, a longboard can still find fun on the rare clean, small day, but overall this is the time to travel or work on your foamie collection.

August: Slight Uptick in Energy, Still Tough

August sees a marginal improvement: average swell height holds at 1.2m but the period bumps to 6.4 seconds. Swell direction is still dominated by ENE (55.5%) and E (36.2%), though a tiny increase in NE (4.5%) and NNE (0.9%) offers a glimmer of hope. Wave heights are mostly 1-1.5m, fun-sized at best. Ideal wind improves to 30%, but the prevailing winds from the E (41.9%) and ENE (29.7%) are still strong. Late summer tropical storms or southern hemisphere swells can occasionally send longer-period energy, but for the most part, August remains a month for small-wave experimentation. Dawn patrol with a south wind can yield clean, rideable waves for longboards and fishes.
