Monte Clerigo seasonal overview
Best Surf Season (October - March)
The North Atlantic roars to life during the autumn and winter months, and Monte Clerigo sits directly in the path of the most consistent swell window in Europe. From October through March, average swell heights range from 6-8ft (1.8-2.5m), with periods climbing into the 11-13s range as extratropical cyclones deepen along the Atlantic storm track. The wave rose is dominated by W, WNW, NW and NNW energy, which lines up perfectly with Monte Clerigo's north-west facing beach. Ideal offshore winds from the SSW, SW, WSW and W blow 25-33% of the time, giving plenty of opportunities for clean, powerful surf. Water temperatures hover between 15°C and 18°C, while rain and storm fronts keep the atmosphere dynamic. This is the season for overhead-to-double-overhead barrels and serious beach break sessions.
Fair Surf Season (April - May & September)
As the polar front migrates north, Monte Clerigo loses some of its winter punch but the ocean remains very surfable. April and May still see average heights of 5-6ft (1.5-1.8m) and periods of 10-11s, with NW/NNW swell still present 70-90% of the time. The main issue is the increasing northerly wind regime, which drops the ideal offshore wind window to 16-19% and can put cross-shore texture on the waves. September is the hinge month where the first Atlantic lows start to brush Portugal again: average wave height sits around 5ft (1.5m), period bumps to 10.6s, and offshore wind days become more frequent than in summer. These shoulder months reward flexibility and dawn patrol sessions.
Low Surf Season (June - August)
Summer is the quiet, fickle season at Monte Clerigo. Average swell heights fall to 4-5ft (1.2-1.5m), periods drop to 8-9s, and the ideal offshore wind window shrinks to just 7-11% of the time. The wave rose is still dominated by NW and NNW swell, but it is mostly short-period, locally generated windswell from the persistent northerly flow that sets up over Iberia. Onshore and cross-shore NW/NNW winds dominate most days, leaving the beach break lumpy and less appealing. The rare clean summer day, usually at dawn with a light southerly breeze, can still deliver fun, rippable walls, but surfers are better off saving their energy for the coming autumn.
