January: Dry-Season Consistency and Southern Groundswell
January is prime dry-season surf at Roca Loca. The average swell height is a modest 3ft (0.9m), but the 12.6-second period keeps the waves organized and punchy. Swell direction is overwhelmingly SSW, making up 86.0 percent of the total energy, with another 12.8 percent arriving from the SW. Although SSW sits a few degrees south of the ideal SW-WNW window, Roca Loca's west-southwest-facing exposure still lines up the swell and offers rideable, wrapping peaks. Winds are light and mostly below 10kph; offshore flow from the NE through ESE quadrant blows clean about 30 percent of the time. With only 1.34mm/day of rainfall, stable high pressure and air temperatures around 26.1°C, the surface is often clean and glassy. Water temperature is a warm 28.4°C. Expect fun-sized, waist-to-shoulder-high waves, with the occasional chest-high set when the SW component kicks in.
