Conditions at Santo Amaro in January
January: The Atlantic in Full Roar
January is Santo Amaro's heaviest month in the calendar, with an average swell height of 8ft (2.5m) and a 13-second period pushing it into the very powerful long-period category. The waverose shows a massive cluster of energy from the WNW and NW directions-roughly 44 percent of all readings-with a strong NNW contribution on top. This north-westerly dominance keeps the beach alive even though the preferred ESE-to-S swell window is rare. The ideal-wind rate sits at 43 percent, meaning a little more than two days out of five will come with offshore N, NW or NNW flow; on those days the long-period lines stack up clean and heavy. Air temperatures average 12.9°C and water sits at 14.8°C, so winter rubber is essential. Periods of ENE or SE wind, often ahead of approaching fronts, can add cross-shore texture, but when the post-cold-front north wind blows, January is as good as it gets.
