Faja dos Cubres seasonal overview
Best Surf Season (October - March)
Faja dos Cubres is a north-facing fajã on the Portuguese island of Sao Jorge, and it lives and dies by the North Atlantic storm track. From October through March, the Azores High retreats south and a conveyor belt of extratropical cyclones flings long-period groundswell toward the archipelago. Average surf heights jump into the 5-6ft (1.5-1.8m) range, periods of 9.5-10.5s put real power in the water, and the south-quadrant winds that blow offshore at this spot become more common as lows stall west of Portugal. When the NAO tilts negative, successive frontal systems line up across the Atlantic and Faja dos Cubres can see days of pumping NW-NNW groundswell with SSW-SW offshore flow. That is the sweet spot of the year at this wild north coast locality.
Fair Surf Season (April - May and September)
April balances lingering winter size with a trend toward smaller, more northerly swell. May cleans up nicely as the Azores High builds, with ideal wind counts rising to 15 percent, but wave heights shrink to 3-4ft (0.9-1.2m) and the period drops into the 8-9s range. September is the mirror image: the ocean begins waking up after the summer lull, with the first solid NW groundswell pulses of autumn while the water is still 22°C. These shoulder months can deliver clean, rippable waves, but they are less dependable than winter. If the high pressure parks overhead, you might be groveling on 2-3ft (0.6-0.9m) leftovers.
Low Surf Season (June - August)
Summer is the quietest time on the north coast. The Azores High locks in, the North Atlantic storm track shifts toward Iceland, and average swell heights sink to 2.5-3ft (0.8-0.9m) with periods of 8.5s or less. That said, Faja dos Cubres still sees northeast and north-northwest windswell pulses, and the percentage of light offshore wind days is actually at its annual high, reaching 19-22 percent. For a smaller north-facing fajã, this is more of a longboard and SUP season than a board-shredding winter, though the occasional late-August hurricane swell can throw a sneaky 3-5ft (1-1.5m) set onto the cliffs.
