Oceanside Pier - surf spot statistics

Oceanside Pier offers consistent swell throughout the year, with the highest frequency of ground swell occurring from June to October, peaking in September at 94%. During these months, wind swell is minimal (6–10%), and chances of flat conditions are virtually zero. However, wind quality is a limiting factor, as offshore winds (good conditions) are relatively rare, ranging from 21% to 43% annually—August stands out with the best wind conditions at 43%. The mean swell size remains modest, averaging 0.8–1.0m, with slightly larger waves in May (1.0m). Winter months (November–February) see more variable swell, including a higher likelihood of wind swell and occasional flat spells, along with worse wind conditions (only 21–32% favorable winds). Overall, late summer (August–September) provides the most reliable combination of consistent ground swell and relatively better wind conditions, though surfers should expect smaller waves. Early winter (December–January) can still deliver surfable conditions but with higher wind interference and less predictability. For surfers prioritizing wave consistency over size, Oceanside Pier remains a year-round destination, with optimal conditions clustering around August and September when swell reliability and wind chances align best.

February at Oceanside Pier offers surfable conditions, though not consistently ideal. The average swell height is 0.9m with a strong 13.7s period, providing decent energy for rides. Most waves are in the 0.5-1.5m range, primarily from the WSW, W, and SW directions, ensuring a favorable swell angle for the break. However, larger waves (1.5m+) are less frequent, with only 5-6% of waves reaching 2m+. Wind conditions are a mixed bag—only 32% of the time are they truly surf-friendly, often coming from the NW, NNW, or S/SSE, which can create onshore chop. When winds are lighter (0-20kph) from the NNE or ENE, conditions improve. Overall, expect smaller but clean waves on good days, with occasional larger sets when the W swell picks up. Patience and timing are key this month.
