January: The Annual Peak in Size

January is the statistical peak of the surf year at Cabo de San Antonio. The average swell height sits at 3.9ft (1.2m) with an average period of 6.7s, placing most waves in the punchy, rideable range. The wave rose is dominated by NNW (14.8%), NNE (11.7%), E (12.0%), and ESE (12.6%) energy, but the south-facing beach is best served by the SSE-SW window, and that sector only accounts for about 7.4% of the total. That means a lot of the winter energy is either wrapped, shadowed, or simply arriving from the wrong side of the compass. Wind is ideal just 16% of the time; the main flow comes from ENE/E/ESE at 10-30kph, adding cross-shore to onshore texture. Still, when a cold front clears the Gulf and a N-NNW offshore lines up with one of those occasional S/SSW pulses, the cape can turn on. Air temperatures average 24.7°C (min 18.0°C, max 28.1°C), water temperature is 26.0°C, and rainfall is moderate at 1.85 mm/day.
