Conditions at Shipwreck Beach in January
January: Peak Winter Groundswell
January is the apex of the surf year at Shipwreck Beach. The average swell height pushes to about 8ft (2.4m) and the average period sits at a powerful 12.4s, a reflection of strong extratropical cyclones firing across the North Pacific. NNW swell accounts for more than 20 percent of the directional spectrum, with NW and NNE/NE contributions also bringing solid, wrapping groundswell into this south-facing shore. The theoretical optimal south swell is almost absent, but the beach makes the most of wrapping NNW/NW energy, especially when a morning N/NNW offshore flow cleans it up. Ideal wind blows 26 percent of the time, mostly under N/NNW influence, while the prevailing ENE trades add cross-shore texture. With air temperatures around 22.8°C, water temperatures near 24.2°C and moderate rainfall around 2.2 mm/day, January remains one of the most consistent months for heavy, lined-up surf.
