Matadouro - surf spot statistics

Best Surf Season (October - March)

The North Atlantic roars to life during these months as the polar jet stream strengthens, spawning powerful extratropical storms that march eastward toward the Portuguese coastline. Matadouro, with its west-facing exposure, sits right in the firing line for the dominant NW and WNW swells, which average 2.3-2.6m and carry long periods of 12-13s. This translates to pumping, heavy waves that can reach firing heights in the 1.5-2.5m range, with occasional XL pulses exceeding 2.5m. The ideal offshore wind from the east quadrant blows 20-27% of the time, creating clean, glassy faces. When the stars align, you get classic Portuguese beachbreak perfection.

Fair Surf Season (April & September)

These transition months see a slight easing in swell energy as the storm track shifts north. Average heights drop to 1.6-2.0m and periods settle into the 10.5-11.1s range, still delivering fun, solid waves in the 1-1.5m class and occasional pumping sets. NW and WNW swells still dominate, but the wind window narrows: ideal offshore conditions occur only 14-15% of the time, with increasing northerly winds creating side-shore chop. Still, there are plenty of rippable days with the right timing.

Low Surf Season (May - August)

Summer settles in with a dramatic drop in both swell size and period. Average wave heights fall to 1.4-1.7m and periods shrink to 8.5-9.9s, yielding mostly small, fun-sized waves in the 0.5-1.5m range. The dominant swell shifts to shorter-period NW and NNW swells, often choppy and messy. Compounding the issue, strong northerly winds dominate the pressure gradient, blowing side-shore or onshore over 50% of the time. Ideal offshore wind days are rare, ranging from 3-11%, making this the least consistent season. However, early mornings or late evenings can still offer groveling sessions when a background swell aligns with a light land breeze.

June: Midsummer Lull

June bottoms out: average swell height 1.5m, period 9.2s – average, punchy. Swell directions are heavily skewed toward NNW (40.5%) and NW (32.0%), with short-period energy. Most waves fall in the 1-1.5m and 0.5-1m categories. Ideal wind is a mere 6%. The N wind (35.6%) rages, with speeds 20-40 kph common, causing messy onshore surf. Rare windows for groveling exist with early easterly breezes.
