Conditions at Sao Lourenco in January
January: The North Atlantic at Full Roar
Sao Lourenco is squarely in the firing line this month. The average swell height jumps to 2.6m (8.5ft) and the average period sits at a powerful 13.0s, driven by a relentless sequence of extratropical cyclones rolling across the North Atlantic. The waverose shows NW and WNW swells dominating the spectrum, with a solid chunk of 2-2.5m (6.6-8.2ft) energy and occasional XL sets over 2.5m (8.2ft).
Winds are the great variable. NNW and NNE flows combine for nearly a quarter of all observations, and the offshore east-southeast quadrant is only fully favorable 25 percent of the time. When a European high pressure ridge sets in and winds clock around to the east or southeast, those long-period WNW/NW lines groom into clean, heavy, firing waves. Air temperatures average 11.5°C with water at 14.4°C, so winter rubber is essential.
