Conditions at San Blas in January
January: Small but Perfectly Formed
January lands right in the heart of the dry season, and the low-surf theme is obvious: average swell height is 3ft (1.0m), but the 12.1s average period keeps it far from flat. The swell window is dominated by SSW (53.6%) and S (26.6%) directions, with a solid 87.7% of all energy arriving from the S/SSW/SW/WSW quadrant. Most waves fall in the 2-3ft (0.5-1m) category, although there is a meaningful 18.5% of SSW swell in the 3-5ft (1-1.5m) range for the better winter windows.
Winds are the saving grace. The offshore quadrant (N/NNE/NE/ENE) supplies 48.1% of the wind, led by NNE at 10-20kph, and the clip of ideal surfing sits at 61%. Light S/SSW sea breeze only shows up 11.6% of the time, mostly at gentle speeds. With air temps averaging 26.2°C, water at 27.8°C and just 0.15mm/day of rain, you get warm, groomed, glassy conditions more often than the modest size would suggest. Grab a log or a mid-length and enjoy the clean, user-friendly lines.
