Conditions at Supertubos in January
January: The Peak of the North Atlantic Engine
January is the heart of the North Atlantic storm track. A near-constant procession of deep lows spins up between Greenland and the Bay of Biscay, sending long-period ground swell toward Peniche. The average swell height sits at a solid 9.2ft (2.8m) with an average period of 13.1s - firmly in the powerful to very powerful range. The swell window is ideally skewed: NW delivers 18.4% of the energy, WNW 15.2%, and NNW 8.0%, meaning the beach's west-southwest exposure is under constant attack. Most of these waves are in the 1.5-2.5m class, with a significant share of 8ft+ sets. Wind conditions are favourable on 43% of the days, as the NE, ENE, E, and ESE offshore winds blow clean and sometimes light. The result is a sandbar that hollows out into long, cranking barrels. Air temperatures average 12.2°C, but the water sits at 14.4°C, so a steamer hood and booties are the call for marathon sessions.
