Conditions at Troia in January
January: Deep-Winter Power and Peak Offshores
January is the statistical apex of the European winter surf calendar at Troia. The average swell height hits 6-7ft (2.0m), with a long, powerful 13.0 second period. Most of that energy comes from the WNW/NW quadrant - together roughly 60% of all wave directions - but the W component delivers 9.6% and the SSW/SW window adds another 1.7%, giving the southwest-facing beach plenty of direct-hit potential. The bigger story is the wind. Ideal conditions clock in at 47%, the highest of the year, with offshore NNE/NE/ENE/E flow making up about 34% of the wind rose. The persistent NNW winter breeze (15.1%) can add texture, but when high pressure over Spain meets lows off the Portuguese coast, dry easterly wind combines with powerful W/SW groundswell to produce clean, heavy, long-period surf. Air temperatures average 10.5°C with 2.14mm of rain per day, and water temperature sits around 15.0°C - so come winter, bring a 4/3 and pick your swell window.
