Playa Boca Chica - surf spot statistics

Best Surf Season (October – March)

The heart of the winter season delivers the most consistent combination of quality swell and favourable offshore winds. As the North Pacific storm track intensifies, long-period groundswells from the SSW and SW window pour into the south-facing beach, averaging 1.0–1.3m with periods often exceeding 13 seconds. The dominant high-pressure systems over the continental US and northern Mexico drive a steady stream of light to moderate offshore airflow from the N, NNE, NE, and NNW, grooming the waves to perfection. This is when Playa Boca Chica truly shines – smooth, peeling rights and lefts, with plenty of punch and clean faces for carving.

Fair Surf Season (July – September)

During the heart of summer, the swell source shifts. The northern hemisphere storm track weakens, but distant Southern Ocean storms and early-season tropical activity in the Eastern Pacific send pulses of SSW and SW swell at 1.4–1.6m with excellent 13–14 second periods. The catch? The wind regime becomes more fickle. Light onshore breezes from the SW and WSW creep in about half the time, introducing a crumbly texture to the surface. Still, when a high-pressure ridge builds in from the north and delivers those crucial offshore flows, the waves turn clean and powerful. It’s a window of opportunity for the patient surfer.

Low Surf Season (April – June)

Autumn and early winter – April through June – represent the slump in both swell size and wind consistency. The average swell height still reaches 1.4–1.6m due to lingering Southern Ocean swells, but the wind becomes the limiting factor. Offshore wind frequencies drop to just 41–46%, meaning most days feature onshore or cross-shore flow from the S through WSW quadrants. The waves, while not small, are often chopped up and lack the clean, lined-up quality that makes this beach break. It’s the trade-off season: you may score a fun session if a cold front pushes through, but expect plenty of marginal conditions.

December: Prelude to the Peak

December sets the stage for the winter peak. Offshore wind frequencies reach 60%, with N winds at 17.8%, NNE at 14.3%, and NNW at 12.0%. The average swell height is 1.1m and period 13.3s. Swell directions are dominated by SSW (47.8%) and SW (38.1%), with a smaller contribution from WSW (10.1%). The wave height spectrum shows a majority in the 1–1.5m range (28.4%) and 0.5–1m range (17.8% from SSW, 15.2% from SW). Despite the slightly smaller average size, the combination of long periods and frequent offshore winds creates excellent surfing conditions. The waves are often clean, with a powerful, punchy shape. December is a favourite for local surfers who know that the window of high‑quality, low‑wind swell is wide open.
