Supertubos Surf Season
Peniche, Portugal · part of the Supertubos spot guide
Prime is October to March, driven by North Atlantic groundswell, with autumn — especially October — repeatedly singled out as the sweet spot when the sandbars are well-formed after summer and the groundswells are strong, long-period and crisp; February is statistically the most consistent clean month. The WSL event ran here in October through the 2010s and has since moved to March, so both autumn and early spring have delivered contest-quality surf. Summer is generally smaller and less consistent.
Where the swell comes from
North Atlantic extratropical lows tracking toward Iberia and the Bay of Biscay generate the long-period west-to-northwest groundswell; closer, deeper lows add west-southwest swell and onshore wind.
Historic swells at Supertubos
Inaugural Rip Curl Pro Portugal
After a 2009 event proved the wave, the tour made Peniche a permanent fixture; Kelly Slater won the 2010 event in the year of his tenth world title.
First winter edition
The contest shifted from its traditional October slot to March to meet the full power of the North Atlantic in cold water, and has stayed in March since.
